Answer:

3(14 + 19)

Step-by-step explanation:

From the given information:

We are being told that Nate spent 42 + 57 at a store.

To find another expression that shows how much Nate spent at the store.

Then, we need to factorize 42 + 57

i.e.

We will look for the lowest factor that is divisible by both 42 and 57.

So, the lowest factor divisible by both 42 and 57 is 3

42 + 57 = 3(14 + 19)

Thus, another expression that shows how much Nate spent at the store is  3(14 + 19)

Answer:

(4x - 3)(x + 1)

Step-by-step explanation:

=4x² + x - 3

=4x² + 4x - 3x - 3

=4x(x + 1 ) - 3( x + 1)

=(4x - 3)(x + 1)

Answer:

(5,15)

Step-by-step explanation:

Check x = 0,the P(x)=-225 : not an inequality solution

Check x = 10 to get -3*-5*5> 0 solutions in 5< x < 10

Check x = 20 to get -3*+5*+15<0 so no solutions in (15,+inf)

Ans: Profit for (5,15)

Answer:

The roots of the quadratic equation  are  , .

Step-by-step explanation:

The roots of the quadratic equation  are  , .

Step-by-step explanation:

As given the equation in the form

Simplify the above equation

(x-2)-x = 3x × (x-2)

x-2 - x = 3x² - 6x

3x² - 6x + 2 = 0          

As the equation is written in the form ax² + bx + c = 0

a = 3 , b = -6 , c = 2

Put all the values in the above equation

Thus

Therefore the roots of the quadratic equation  are  , .

Answer:

All real numbers are solutions to this problem.

Step-by-step explanation:

I) Simplify:

2(x + 4) - 1 = 2x + 7

x + 4 - 0.5 = x + 3.5 (Divide by 2)

x + 3.5 = x + 3.5 (Simplify x + 4 - 0.5)

x = x

II) Conclusion:

Any real number will work as a solution.

Answer:

[tex]a\geq 16[/tex]

Step-by-step explanation:

Let [tex]a[/tex] represents the age at which a person gets a student learner's permit to drive in New Jersey.

Also, an individual must be at least [tex]16[/tex] years old to get a student learner's permit to drive in New Jersey.

So, inequality is [tex]a\geq 16[/tex]

(Inequality explains a relationship of greater than or greater than or equal to or less than, or less than or equal to between two mathematical expressions)

Answer:

x = 5

Step-by-step explanation:

Since ∠P ≅ ∠P and  ∠PST≅ ∠PRQ (corresponding angles are congruent when the lines are parallel), ΔPST is similar to ΔPRQ by the AA postulate

Therefore, corresponding sides are in proportion.  

PS ↔ PR and ST ↔ RQ

[tex]\frac{PS}{PR} = \frac{ST}{RQ} \\\frac{x + 7}{2x + 6} = \frac{6}{8}[/tex]   Note:  PR = PS + SR = x + 7 + x - 1 = 2x + 6

8(x + 7) = 6(2x + 6)

8x+56 = 12x + 36

4x = 20

x = 5

Answer:

Step-by-step explanation:

one point is (-2,5)

5y-25=-11x-22

11x+5y=25-22

11x+5y=3

5y=3-11x

[tex]y=\frac{3-11x}{5} \\x=-2,y=5\\x=3,y=-6\\[/tex]

so points are (-2,5) and (3,-6)

draw a line through these points.

Step-by-step explanation:

Calculate the distance d using the distance formula

d = [tex]\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2 }[/tex]

with (x₁, y₁ ) = (- 4, - 6) and (x₂, y₂ ) = (- 9, 6)

d = [tex]\sqrt{(-9+4)^2+(6+6)^2}[/tex]

   = [tex]\sqrt{(-5)^2+12^2}[/tex]

Answer: -1/25 / -1/5 / 1/25

Step-by-step explanation:

Answer:

Kayla = $20.14

Michael = $19.08

The Difference = 1.06

Step-by-step explanation:

How to solve.

First, you need to add up how much Kayla is paying for the video game, plus the 6% tax.

19.00 + 6% = 20.14

Then, you need to do the same with Michael's.

18.00 + 6% = 19.00

To find the difference between how much Kayla and Michael paid for their items, you need to subtract their total.

20.14 - 19.00 = 1.06

and the nearest cent would be 1.10.

Answer:

Step-by-step explanation:

90(5/6)

450/6

75

9514 1404 393

Answer:

  75

Step-by-step explanation:

90 = 6 × 15

There are 15 6-day periods in 90 days. The gardener will have mowed ...

  15 × 5 = 75

times in those 15 periods.

He will mow 75 times in a 90-day period.

__

If you like, you can set up a proportion for the unknown number of mowings (m).

  mows/days = m/90 = 5/6

Multiply by 90 to solve for m.

  m = 90(5/6) = (90/6)(5) = 15(5) = 75 . . . . . . this should look like the above

Answer:

A (the first one)

Step-by-step explanation:

open image I

Answer:

because this is a parallelogram

=> 3t - 15 = 2t + 10

⇔ t = 10 + 15

⇔ t = 25

with t = 25 => 3t - 15 = 3.25 - 15 = 60

we also have:

4r + (3t - 15) = 180°

⇔ 4r + 60° = 180°

⇒ 4r = 120°

⇔ r = 30

we also have;

4r = 3s

=> 4.30 = 3s

⇔ s = 4.10

⇔ s = 40

Step-by-step explanation:

You can use the fact that sum of all angles of a parallelogram is 360 degrees and the sum of two adjacent angles in a parallelogram is 180 degrees.

The value of the variables used in the figure are:

r = 30

s = 40

t = 25

[tex]4r + (3t - 15) + (2t + 10) + 3s = 360^\circ\\4r + 3s + 5t = 365[/tex]

And

[tex]3t - 15 + 4r = 180 \cdots (1)\\3t - 15 + 3s = 180\cdots (2)\\3s + 2t + 10 = 180\cdots (3)\\4r + 2t + 10 = 180\cdots (4)[/tex]

We get 2 systems of linear equations.

First system consists of equation 1 and equation 4

Second system consists of equation 2 and equation 3

From equation 1 and 4, as both's left side is equal to 180, thus they are equal too, or

[tex]3t - 15 + 4r = 4r + 2t + 10\\3t - 2t = 4r - 4r + 10 + 15\\t = 25[/tex]

Putting it in equation 1, we get:

[tex]3t - 15 + 4r = 180\\3 \times 25 + 4r = 180 + 15\\75 + 4r = 195\\\\r = \dfrac{195 - 75}{4} = 30[/tex]

Putting the value t = 25 in second equation, we get:

[tex]3t - 15 + 3s + 180\\3 \times 25 - 15 + 3s = 180\\60 + 3s = 180\\\\s = \dfrac{180 - 60}{3} = 40[/tex]

Thus, the values of the specified variables in the given graph are:

r = 30

s = 40

t = 25
