10x + 5= 15x - 10

5= 5x - 10

15 = 5x
divide both sides by 5

x = 3

Rubin drew this diagram of his garden.how can you dividethe shape to find the area?

Kaylis [27]

ANSWER

We can divide in to two rectangles as in the attachment.

We then find the area of each rectangle and add together.

The area of the bigger rectangle is

$A_1= 4\times 8$

$A_1= 32 m^2$

The area of the smaller rectangle i

$A_2= 4\times 6$

$A_2= 24 m^2$

Hence the area of the figure is

$Area=32+24$

$Area=56 m^2$

What is the solution to the equation 1/4x - 1/8 = 7/8 + 1/2x ?

lyudmila [28]

Hey there! I'm happy to help!

We want to get all of the variables on the left side and all of the numbers on the right side. This will allow our variable to be isolated so we can see what it is equal to.

1/4x - 1/8 = 7/8 + 1/2x

We add 1/8 to both sides.

1/4x=1+1/2x

We subtract 1/2x from both sides.

-1/4x=1

We divide both sides by -1/4 (same thing as multiplying -4).

B. x=-4
