I did comment asking if the two you'd already selected were definitely correct, but no answer was given, so I apologise if this is wrong. This is what I would put.
7x+1000+x=89000
7x+x+1000-1000=89000-1000
8x=88000
8x/8=88000/8
x=$11000
Answer:
First question --> C) 8.5h
Second question --> D) 2
Step-by-step explanation:
First question
Terry earns $10 per hour
Jill earns 20% less which is $2 less
Jill earns $8 per hour
Jerry earns $0.50 more per hour than Jill
Jerry earns $8.50 per hour
Second question
x = 2
y = 4
(2x + 3y) / 4 - 2 = ?
Use PEMDAS
so Parentheses first, then divide, then subtract
So.... (2x + 3y) = (2*2 + 3*4) = (4 + 12) = 16
Then divide
16/4 = 4
Then subtract
4 - 2 = 2
Hypotenuse by Pythagoras theorem = 407.83.
