4. x = 50

5. x = 5

Step-by-step explanation:

For question 4:

For question 5:

Answer:

4) x= -50

5) x= 5

Step-by-step explanation:

Number 5

Simplifying

-3x + -2 = -17

Reorder the terms:

-2 + -3x = -17

Solving

-2 + -3x = -17

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '2' to each side of the equation.

-2 + 2 + -3x = -17 + 2

Combine like terms: -2 + 2 = 0

0 + -3x = -17 + 2

-3x = -17 + 2

Combine like terms: -17 + 2 = -15

-3x = -15

Divide each side by '-3'.

x = 5

Simplifying

x = 5

Number 4

x/5+7 = -3 // + 3

x/5+3+7 = 0

1/5*x+10 = 0 // - 10

1/5*x = -10 // : 1/5

x = -10/1/5

x = -50

x = -50

I believe you subtract 13 1/4 by 10 3/4 = 2 1/2.

Then you divide by 5.

Answer: 3x²-3y²+8xy

Step-by-step explanation:

When you multiply two factors, you want to use the FOIL method.

First

Outer

Inner

Last

(x+3y)(3x-y)                  [distribute by FOIL]

3x²-xy+9xy-3y²            [combine like terms]

3x²+8xy-3y²                 [rewrite]

3x²-3y²+8xy

Now, we know the product is 3x²-3y²+8xy.

Answer:

The answer is

Step-by-step explanation:

The distance between two points can be found by using the formula

[tex]d = \sqrt{ ({x1 - x2})^{2} + ({y1 - y2})^{2} } \\ [/tex]

where

(x1 , y1) and (x2 , y2) are the points

From the question the points are

(-1,-7) and (8,-9)

The distance between them is

[tex]d = \sqrt{( { - 1 - 8})^{2} + ({ - 7 + 9})^{2} } \\ = \sqrt{ ({ - 9})^{2} + {2}^{2} } \\ = \sqrt{81 + 4} [/tex]

We have the final answer as

[tex] \sqrt{85} \: \: \: units[/tex]

Hope this helps you

Step-by-step explanation:

Hey there!!!

Here,

The point is, (-3,1).

Using one point formula.

(y-1)= m(x+3)....1st equation.

It has said that it is also perpendicular to the line y = 1/3x + 2 .......2nd equation.

Now, the equation with y = mx + c.

We get slope (m2) = 1/3.

Now,

As per the condition of perpendicular lines,

[tex]m1 \: \times m2 = - 1[/tex]

[tex]m1 \times \frac{1}{3} = - 1[/tex]

Simplifying them we get,

m1 = -3.

Therefore the slope is -3.

Answer:  (2x-y)^2

Step-by-step explanation:

The area of a square is given by the formula A = s^2.  

We know that the length of one side is s = 2x-y.  We can substitute this into our area equation:

A = (2x-y)^2

If you need to multiply out the answer:

A = (2x-y)(2x-y)

A = 4x^2-4xy+y^2

Answer:

360 feet.

Step-by-step explanation:

Let x = length, then the width is 4x/9 feet.

So we have the equation:

x * 4x/9 = 57600

4x^2 / 9 = 57600

4x^2 = 57600 * 9

x^2 = 57600 * 9 / 4

x = √57600 * 3 / 2

x = 240* 3/2

x = 360 feet.

Answer:

$640

Step-by-step explanation:

512/0.2 = 2560 quarters

2560 quarters = 640 US Dollars

Hope this helps !

The total amount that was stolen is 640 US dollars.

The weight of the amount is given by;

Weight = 512 ounces

The weight of each quarter will be;

Unit weight = 0.2 ounces

So, the total amount would be;

Total = 512/0.2

Evaluate;

The Total amount = 2560 quarters

1 quarter = $0.25

So, we have:

The Total amount = $0.25 * 2560

Now Evaluate the product

The Total amount = $640

Hence, the total amount that was stolen is 640 US dollars.

Answer:

the mass is 75 kg

Step-by-step explanation:

80 KG

70m/s times forty=2800 divided by 80=35 +40=75

The correct option will be the option b i.e., the maximum.

It is given that Joseph is earning an annual salary of $24,895. Later he is offered with an ad.

We have to choose the correct option i.e., the minimum or the maximum he would earn per month if he is paid.

What would be the value if x is added to 40 ?

The value will be 40 + x.

Let's assume Joseph is paid $ x for the ad.

Annual salary of Joseph $24,895.

The salary which he will get after the ad offer will be ;

= 24895 + x

So , the annual salary get's increased after the addition of salary of ad offer.

Thus , the maximum Joseph would earn per month and the correct option is option b.

Answer:

56cm²

Step-by-step explanation:

To solve this question, find the area of the triangles separately and then add all the areas to find the total area of the kite.

Attached is the image of my work    

Answer:

56 cm²

Step-by-step explanation:

The area (A) of a kite is calculated as

A = [tex]\frac{1}{2}[/tex] product of the diagonals

   = [tex]\frac{1}{2}[/tex] × d₁ × d₂

d₁ = 4 + 4 = 8 and d₂ = 10 + 4 = 14

A = [tex]\frac{1}{2}[/tex] × 8 × 14 = 4 × 14 = 56 cm²
