This is the last one but how do you find y ? what do I subtract 5 from ?

y = 250

Step 1:

To solve, we plug in 50x for y.

Then, we subtract the 10x from the right side. Our goal is to get the x by itself first.

Then, we divide both sides by 40, since we have to get the x by itself.

x = 5

Step 2:

Now that we found x, we plug in 5 to the original equation and solve from there.

y = 250

step-by-step explanation:

d) 30 units^2

area of rectangle = l × b

we know,

length = 10 unit

breadth = 3 unit

applying the formula,

= l × b

= 10 × 3

= 30 unit^2
