Answer: 2x = $90

Step-by-step explanation:

From the question, we are informed that Brady is selling candy bars for a school fundraiser to help pay for new sports uniforms and that he gets paid $2 for every candy bar he sells, and he made a total of $90 on Saturday.

The equation showing the number of candy bars Brady sold on Saturday goes thus:

Let the number of candy bars sold on Saturday be x.

Since each candy bar is sold for $2 and he made a total of $90, this means that the $90 gotten is the product of each candy bar and the amount sold which we represented by x. Therefore the equation will be:

2 × x = $90

2x = $90

We can further solve to get x.

2x = 90

x = 90/2

x = 45

That means 45 candy bars were sold.

Answer:

hi, so i belive the correct option to your question is:

2x = 90

Step-by-step explanation:

it just makes the most sense to me because 2x which could mean two times which in the equation it says he makes to dollars per candy bar sold, so it makes more sence for it to be 2x rather than 90x. and then it says he made a total of ninty dollars on saturday which is a key factor in solving this equation so think it would be 2x = 90$.

im really not sure if this logic makes sence, im not super good with algebra but i hope this helps you out.

Answer:

The answer is option B.

-3 , - 0.9 , 45

Hope this helps you

Explanation:

The negative numbers are always smaller than the positive ones. So we list those first. The number -3 is smaller than -0.9 since it is further to left on the number line. So far we have -3 followed by -0.9. The last value must be 45 as its the only thing left. The sequence from smallest to largest is therefore -3, -0.9, 45. A number line is recommended to see the values being placed from left to right.

Explanation:

SAS stands for Side Angle Side. Note how the angle is between the two sides. To prove the triangles congruent with SAS, we need to know two sides and an angle between them.

We already see that BC = CD as shown by the tickmarks. Another pair of sides is AC = AC through the reflexive theorem.

The missing info is the angle measures of ACB and ACD. If we knew those angles were the same, then we could use SAS to prove triangle ACB is congruent to triangle ACD.

It turns out that the angles are congruent only when they are 90 degrees each, leading to AC being perpendicular to BD. We write this as [tex]\overline{AC} \perp \overline {BD}[/tex]. The upside down T symbol meaning "perpendicular" or "the two segments form a right angle".

Answer:

y = − 2/5x − 11

Step-by-step explanation:

To answer this, we need to put it into y = mx + b form. First, we need to find the slope. The equation for that is:

[tex]m = \frac{-9 - (-7)}{-5 - (-10)}[/tex]

[tex]m = -\frac{2}{5}[/tex]

We now have the slope. Now, we need to figure out b, or the y-intercept. Using y = mx + b, we substitute the slope and an x value (it doesn't matter whether it's -10 or -5, but let's use -10 for now) and a y value (same thing).

[tex]-7 = (-\frac{2}{5})(-10) + b[/tex]

[tex]b = -11[/tex]

All that's left to do is plug it in! Our final answer is:

[tex]y = - \frac{2}{5}x - 11[/tex]

Answer:

[tex]y = - \frac{2}{5} x - 11 [/tex]

Step-by-step explanation:

[tex] (-10,-7) and (-5,-9) \\ x_{1} = - 10 \\ y_{1} = - 7 \\ x_{2} = - 5 \\ y_{2} = - 9[/tex]

[tex] \frac{y - y_{1}}{x -x_{1} } = \frac{y_{2} -y_{1}}{x_{2} - x_{1} } \\ \frac{y -( - 7) }{x - ( - 10)} = \frac{ - 9 - ( - 7)}{ - 5 - ( - 10)} \\ [/tex]

[tex]\frac{y + 7}{x + 10} = \frac{ - 2}{5} \\ cross \: multiply \\ 5(y + 7) = - 2(x + 10) \\ 5y + 35 = - 2x - 20[/tex]

[tex]collect \: like \: terms \: \\ 5y = - 2x - 20 - 35 \\ 5y = - 2x - 55 \\ \frac{ 5y = - 2x - 55}{ 5} \\[/tex]

[tex]y = - \frac{2}{5} x - 11[/tex]

Answer:

We have the relation:

(x + 3)^10

As the degree of the polynomial is 10, we know that we can have 10 roots.

The theorem says that this has at least one complex root.

As you know, this is actually trivial, because for example, 4 can be a complex number with an imaginary part equal to zero.

In this case, the polynomial is only zero if we have x = 3.

Then we have 10 roots that are equal to x = 3.

and those 10 roots can be real, or we can have 10 roots equal to 3 + 0*i, that is a complex number.

Answer:

£7

Step-by-step explanation:

Since the sale is 10% the original price, every item is being sold for 90% of its original price. Now the problem is: £6.30 is 90% of what number?

Let x = original price before sale

6.30 = 0.9x

0.9x = 6.3

Divide both sides by 0.9

x = 6.3/0.9

x = 7

Answer: £7

Answer:

9 cm

Step-by-step explanation:

Every centemeter represents three. 3km=1cm.

The number of kilometers/3= the number of centemeters.

the number of centemeters x 3= the number of kilometers.

We now have three equations to help us covert back and forth.

The question asks us to convert 27km in real life, to centemeters on a map. We use the first forumla to help us:)

The number of kilometers/3= the number of centemeters.

27/3=the number of centemeters.

Thus, the answer is nine.

Answer:

9cm

Step-by-step explanation:

1:3 this is the starting ratio

if we replace 3 for 27 we just divide them to get 9 so the new ratio is 9:27.

Answer:

No

Step-by-step explanation:

Does (3, 7) satisfy the first equation, y = -4x - 5?  Is 7 = -4(3) - 5 true?  NO.  Thus, (3, 7) cannot be a solution of the system

y=-4x-5

y=3x-2

The given point (3, 7) is not the solution in the given case.

A system of linear equations can be defined as a number of equations needed to solve the equations. For n number of variables n number of equations are required.

Given equations are as follows,

y = -4x - 5                                (1)

y = 3x - 2                                 (2)

In order to find whether (3,7) is the solution for them, substitute x = 3 and y = 7 in both the equations and check the LHS and RHS of both.

For equation (1),

y = -4x - 5  

LHS is y  = 7

RHS = -4x - 5

       = -4 × 3 - 5

       = -17

Since, LHS ≠ RHS, the given values of x and y are not the solution for the given equation.

Now, equation(2) need not to be checked as the result for the given values is already not valid for equation(1).

Hence, the given coordinate  (3,7) is not the solution for the given equations.

Answer:

[tex](-14,3)[/tex]  is the required point.

Step-by-step explanation:

Explanation is useless for you.

Best Regards!

Answer:

the coordinates of P are (-14,3)

Step-by-step explanation:

as we know PQ is a line segment and it has a mid-point M in order to find the coordinates of P we use mid-point formula

[tex]M(x,y)=(\frac{x1+x2}{2},\frac{y1+y2}{2} )[/tex]

[tex](-9,8.5)=(\frac{x1+(-4)}{2},\frac{y1+14}{2} )[/tex]

comparing the coordinates separately

[tex]-9=\frac{x1-4}{2}[/tex]        or      [tex]8.5=\frac{y1+14}{2}[/tex]

simplifying the both equations

-9×2=x1-4           or      8.5×2=y1+14

-18=x1-4              or       17=y1+14

-18+4=x1               or       17-14=y1

-14=x1                   or      3=y1

so the coordinates of P are (-14,3)

in order to check the values put it in mid-point formula to find the coordinates of M

Answer:

n= -1/3

Step-by-step explanation:

To find non permissible values (npv), focus on the denominator of an expression

In this case, the denominator is:  (3n+1)

The npv is basically the value that would make the expression equal to 0

So, make the expression in the denominator equal 0

     3n+1 = 0

Solve for n

    3n= -1

    n = (-1/3)

Thus, the npv for this equation is n= -1/3

Answer:

Choices B, D and E.

Step-by-step explanation:

This is simple logic.

If it was choice A, number of outfits won't be lower than number of days.

Choice B is right, because if you do this:

(3×2)(3×2)(3×2)=666 days

or

6÷3=2

(4×2)(4×2)(4×2)=888 outfits

or

8÷4=2

You would know the statement is true.

If it was choice C, it's not correct:

(3×3)(3×3)(3×3)=999 days

(4×3)(4×3)(4×3)=121212 outfits (this is the closest answer because nothing can be multiplied by 4 to get 101010)

So, statement of choice C is incorrect.

Choice D is correct, because of this:

(3×4)(3×4)(3×4)=121212 days

or

12÷3=4

(4×4)(4×4)(4×4)=161616 outfits

or

16÷4=4

E is also correct, because of this:

(3×7)(3×7)(3×7)=212121 days

or

21÷3=7

(4×7)(4×7)(4×7)=282828 outfits.

So the answer is choices B, D and E.

The perimeter of the real playground is 1000(x+y) meters where x and y are the length and breadth of the scale drawing playground.

Perimeter of a rectangle  = 2 (length and breadth)

the scale of the drawing is 1:500

let's assume that the length of the scale drawing playground is x and the breadth of the scale drawing playground is y. therefore, the length of the playground is 500x and the breadth is 500y.

Perimeter of the scale drawing playground = 2(length+breadth)

                                                                        [tex]= 2 (x+y)[/tex]

Perimeter of the real playground = 2(length+breadth)

                                                       [tex]=2 (500x+500y)\\=2 \times 500(x+y)\\= 1000 (x+y)[/tex]

Hence, the perimeter of the real playground is 1000(x+y) meters where x and y are the length and breadth of the scale drawing playground.

Answer:

x = - 7, x = 2

Step-by-step explanation:

Given

x² + 5x - 14 = 0

Consider the factors of the constant term (- 14) which sum to give the coefficient of the x- term (+ 5)

The factors are + 7 and - 2, since

7 × - 2 = - 14 and 7 - 2 = + 5 , thus

(x + 7)x - 2) = 0 ← in factored form

Equate each factor to zero and solve for x

x + 7 = 0 ⇒ x = - 7

x - 2 = 0 ⇒ x = 2
