2/5=m/70
Use cross multiply
70*2=5*m
140=5m
Divided 5 to each side
140/5=5m/5
m=28
Check:
2/5=m/70
Substitute m with 28
2/5=28/70
2/5=4/10
2/5=2/5. As a result, m=28. Hope it help!
You would take 175 and multiply it by 0.20 which is 35. The you would subtract 35 from 175 because it is marked down so you would get 140. Next, you would take 140 and multiply it by 0.10 and get 14. Finally subtract 14 from 140 to get your answer which would be $126.
For rational expressions, all real numbers can be used as inputs, except for those that make the denominator equal to 0 (since division by 0 is undefined).
Thus, the domain restrictions are values that turn the denominator into 0. Since you have (x + 2) (x - 1) as the denominator, then it means that:
For (x + 2), the value of x CANNOT be -2, as it will result into 0.
For (x - 1), the value of x CANNOT be 1 because their difference will have 0 as a result.
Therefore, the correct answers are:
b.) x = 1
c.) x = -2
