1) To solve for x, is to let x on the left side and the other terms and variables on the right side.
bx -10=f <em>Add 10 to both sides</em>
bx = f+10 Divide by b on both sides
So that's the way we solve for x.
b) For this one we multiply the whole expression by 2 and then isolate z on the left side, and the rest on the right side.
z = 2h +2b
Answer: 3,840
8000 * 4 * 12 = 384,000
384,000 / 100 = 3.840
33,000 If you round 3,289 up then in would be 3,300. And 7 rounded up would be 10. So 3,300 x 7 = 33,000
3(9)-2
27-2
25
25 is your answer
