Hi there!

I believe your answer is:

$\huge x=-6$

»»————-　★　————-««

Here’s why:

⸻⸻⸻⸻

$\boxed{\text{Solving for 'x'...}}\\\\-8x-4(x-4)=88\\-------------\\\rightarrow -8x-4x+16=88\\\\\rightarrow -12x + 16 = 88\\\\\rightarrow -12x + 16 - 16 = 88 - 16\\\\\rightarrow -12x = 72\\\\\rightarrow \frac{-12x=72}{12}\\\\\rightarrow \boxed{x=-6}$

⸻⸻⸻⸻

Hope this helps you. I apologize if it’s incorrect.

170 mph * 0.75 hr = 127.5 miles flown

127.5 - 12.5 = 115

Lunch break is 1 1/4 hours long Lunch break ends at 1:30pm At what time does it start?

sasho [114]

Lunch starts at 1:30. So 1/4 of 1 hour is 15 minutes. Subtract 1 hour or 60 minutes from 1:30, which equals 12:30. So you have 1/4 remaining, so subtract 15 minutes from 12:30, giving you a final answer of 12:15.
