The results of her effort can be grouped
into two general categories:

X=10
First, remove the parentheses so it could turn into 150-2x-90=4x (the plus sign gets turned into a minus sign because of a certain rule.
Then do 150-90 which will result in 60-2x=4x.
Then subtract -4x on both sides. This will leave you with 60-6x=0.
Next, subtract 60 in both sides. This will leave you with -6x=-60.
Finally, divide by -6 on both sides. This will leave you with the answer x=10.
Answer:
Step-by-step explanation:
[8 * (7÷7)]² = [8 * 1]²
= 8²

The operation in the inside parenthesis should be done first.
Y/x = 7/2
Cross multiply.
2y = 7x
Solve for y.
y = 7/2x
C) The slope of the line is 7/2
D) The y intercept is 0
