How do you do the bottom portion of this? it’s my younger sister’s homework . i’m a sophomore and have no idea how to do it!

Hello!

Looking at how you set up the proportion, it is correct.

Although, the multiplication is incorrect.

You are supposed to multiply 68 by 25 which comes out to 1700. Then, you should divide it by 100 to get x = 17.

(divide both sides by 100)

Therefore, you should expect Sparky to catch it 17 times.

just do 5.2 + 2 ( 7.2) and 1/3 x 3 (.9) and youv'e got your equation. 0.9( 9/10) + 7.2 ^2 = 16.4 hope i could !

step-by-step explanation:

no this is a nonlinear negative
