I was going to try to do it some fancy equation way, but i couldn't seem to manipulate any of my equations just the right way.

But.....I did come across the answer by chance while testing something in my calculator.

so, if y is the length of the original side of the square and x is the new length:
x+2=y

4x=perimeter of original square
4x=10+y
or
4x=10+(x+2)

I plugged 4 into this by chance and look what we have from that:
4x=10+(x+2)
4•4=10+(4+2)
16=10+6
16=16
Bingo!!! it's a match!

so the new length of one side is 6 inches.

How do I answer this question

First you have to make it multiplication so you flip 5/2 around and the two “2’s” will cancel each other so it will be 17/5 or 3 2/5

A rectangular athletic field is twice as long as it is wide. if the perimeter of the athletic field is 192 yards, what are its

qaws [65]

P = 2(L + W)
P = 192
L = 2W

192 = 2(2W + W)
192 = 2(3W)
192 = 6W
192/6 = W
32 = W <=== the width is 32 yards

L = 2W
L = 2(32)
L = 64 <=== the length is 64 yards

Create an expression to represent the following<br><br> (picture is included below)

zheka24 [161]

Answer:

7) x + 0.09x, where x is the price of the car

8) x + 0.05x where x is the price of clothing

9) It will take michael about 9.14 minutes to eat 32 cookies.

Step-by-step explanation:

7) 9% of x is the same as 0.09x, so you can write this:

x + 0.09x, where x is the price of the car

8) same thing for this one

x + 0.05x where x is the price of clothing

9) michael can eat cookies at a rate of 21 cookies per 6 minutes, or $\frac{21}{6}$

Because he will be eating them at the same pace, you can write an equation and solve for the variable:

$\frac{21}{6}$ = $\frac{32}{y}$

cross multiply the proportion:

21 × y = 32 × 6

solve:

21y = 192

y ≈ 9.14

It will take michael about 9.14 minutes to eat 32 cookies.

This works because they both simplify to 3.5 cookies per minute

$\frac{21}{6}$ = 3.5

$\frac{32}{9.14}$ = 3.5
