Find the perimeter of the figure
77julia77 [94]

Answer:

51

Step-by-step explanation:

Hey There!

To find the perimeter of any figure all you have to do is add up all of the side lengths

5+5+7+11+7+16=53

so the perimeter is equal to 51

Note: the 18 is from the bottom length of the figure

you would have to add the 5 and 11

the extra seven is from the very right side length

Help this confusing no matter how any times I do it
3241004551 [841]

Answer:

The variable 8. Equation is 16 + 12x = 112.

Step-by-step explanation:

We know that she spent $16 dollars on magazines, so we can put it in the equation (16 + x= ?). We also know that the total is $112, so we can also add that (16+ x= 112). We don't know how many books she got, but we do know how much they cost (16 + 12x=112. So that makes  the books the variable (X).

To find the variable we need to take out the magazines from the price. 112-16=96. Now we're left with 12x=96. Now all we have to do is divide 96 by 12, which equals 8.

Sorry everything is so long, I tried to make it short as possible
