Answer:
x = 2
Step-by-step explanation:
Given

1 + 3x = 7 ( subtract 1 from both sides )
3x = 6 ( divide both sides by 3 )
x = 2
Cf=cold faucet rate
hf=hot faucet rate
cf*18min=1 tub
(cf+hf)*8min=1 tub
cf+hf=1tub/8min
cf=1tub/18min
hf=(1/8-1/18)tubs per minute
hf=5/72
It takes 14.4 minutes.

Answer: 10.5 is my guess
Step-by-step explanation:
1. 30% = 8.4
100 x
cross multiply
30(x) = 840

2. 37.5% = y
100 28
cross multiply
1050 = 100y
divide both sides by 100 = 10.5
