Answer:

x=21/40

Step-by-step explanation:

First get common denominators

3/8 *5 to top and bottom is now 15/40

3/20 *2 to top and bottom is now 6/40

isolate the X

x-15/40=6/40

+15/40    +15/40

x=21/40

Answer:

x = \frac{21}{40}

Step-by-step explanation:

Given

x - \frac{3}{8} = \frac{3}{20}

Multiply through by 40 ( the LCM of 8 and 20 ) to clear the fractions

40x - 15 = 6 ( add 15 to both sides )

40x = 21 ( divide both sides by 40 )

x = \frac{21}{40}

two pumps of different sizes, working together, can empty a fuel tank in 3 hours. the larger pump can empty the tank in 4 hours
bonufazy [111]
Suppose the larger pump alone can empty the tank in L hours, and the smaller pump can finish the job in S hours, then each hour the large pump empties 1/L portion of the tank, and the small pump empties 1/S per hour
Working together for three hours, they empty the whole tank, which is 100% of it, so 3/L+3/S=100%=1
Larger pump can empty the tank in 4 hours less than the smaller one, so L=S-4
replace L: 3/(S-4)+3/S=1
Make the denominator the same to solve for:
3S/[S(S-4)] +3(S-4)/[S(S-4)]=1
(3S+3S-12)/[S(S-4)]=1
(3S+3S-12)=[S(S-4)]
S^2-10s+12=0
use the quadratic formula to solve for S
S is about 8.6
The answer is not whole hour.
