Question

please some one help me

1.Finance After taxes, Alexandra’s take-home pay is 7/10 of her salary before taxes. Write and solve an equation to find Alexandra’s salary before taxes for the pay period that resulted in $392 of take-home pay.

2.Earth Science Your weight on the Moon is about
1/6 of your weight on Earth. Write and solve an equation to show how much a person weighs on Earth if he weighs
16 pounds on the Moon. How could you check that your answer is reasonable?

Answer 1

1. 7/10 of s = t , 7/10s = t
where s stands for salary and t stands for take home pay.
if t = 392....
(7/10)s = 392
s = 392/(7/10)
s = 392 x 10/7
s = 3920/7
s = 560

Her salary was $ 560

2. m = 1/6e
where m stands for moon weight and e stands for Earth weight
where m = 16
16 = 1/6e
16/(1/6) = e
16 x (6/1) = e
96 = e

check...16 = (1/6)96
16 = 1/6 x 96/1
16 = 96/6
16 = 16 (correct)

16 lbs. on the moon = 96 lbs. on Earth
