Answer:

x = -2

Step-by-step explanation:

The x coordinate of the midpoint is found by adding the x coordinates together and dividing by 2

( -4+0)/2 = -4/2 = -2

The y coordinate of the midpoint is found by adding the y coordinates together and dividing by 2

( 8+10)/2 = 18/2 = 9

Write and expression to find the perimeter of a rectangle with a length of 8 mm and width of x mm
Mrrafil [7]

Answer:

P=16+2x

Step-by-step explanation:

The formula for finding the perimeter of a rectangle is P=2l+2w.

Plug the length of 8 and the width of x into the formula.

You'll get P=2(8)+2(x).

Multiply. 2•8=16 and 2•x=2x.

Your expression is P=16+2x.

I hope this helps.

Solve the system of linear equations: 1/5 x + 1/8 y = 1 1/2 x − 1/3 y = 1
Alchen [17]

Answer:

x = 75 and y = -72

Step-by-step explanation:

It is given that,

1/5 x + 1/8 y = 1   ------(1)

1/2 x − 1/3 y = 1  -------(2)

<u>To find the solutions of the system of equations</u>

Step 1: eq(1) * 5 ⇒

x + 5/8y = 5  ----(3)

Step 2:  eq(2) * 2 ⇒

x - 2/3y = 2  -----(4)

Step 3: eq(3) - eq(4) ⇒

x + 5/8y = 5  ----(3)

<u>x - 2/3y = 2  -</u>----(4)

0 +(5/8 - 2/3)y = 3

 -1/24 y = 3

y = -24*3 = -72

Step 4: Substitute the value of y in eq(1)

1/5 x + 1/8 y = 1   ------(1)

1/5 x + 1/8 (-72) = 1   ------(1)

1/5 x  - 24 = 1

1/5 x = 25

x = 5*25 = 75

Therefor x = 75 and y = -72
