Answer:
I can tell you the first one and you can figure it out from there. 70 is 40% persent of what number? Well, we can chop 40% to 20% and chop 70 in half and we get 35. So 35 = 20% So we multiply 35 by five, and get 175. So 70 is 40% of 175.

Answer:
the answer is D
Step-by-step explanation:
hard to explain it with just words and not be able to show you step by step
When 1-5x>0, 1> 5x, x< 1/5, then |1-5x|=1-5x
6(1-5x)-9=57
6-6*5x-9=57
-30x-3=57
-30x=57+3
-30x=60
x=-60/30
x=-2 is a solution because -2<1/5
