PL HELP 1.) Water is being drained from a tank, containing 1000 gallons of water, at a
constant rate. After 10 minutes there are 940 gallons of water remaining in the
tank. How much water remained in the tank after 5 minutes? 20 minutes? 30
minutes? 27 minutes? X minutes? What is the rate of flow of the water from the
tank?

Step-by-step explanation:

the constant drain of water is C:

C= (1000-940)/10 = 6 gallons per minute

after x minutes : 1000- 6x ( water left in the tank after x minutes)

for 5 minutes: 1000-6(5)=970

after 20 min.: 1000-6(20)=880

after 30 min.: 1000-6(30)=820

after 27 min.: 1000-6(27)= 838

the rate of flow of water is 6 gallon per minute

5x+10 is the correct one

hope this

simplifying

5(x + -6) = 2(x + 3)

reorder the terms:

5(-6 + x) = 2(x + 3)

(-6 * 5 + x * 5) = 2(x + 3)

(-30 + 5x) = 2(x + 3)

reorder the terms:

-30 + 5x = 2(3 + x)

-30 + 5x = (3 * 2 + x * 2)

-30 + 5x = (6 + 2x)

solving

-30 + 5x = 6 + 2x

solving for variable 'x'.

move all terms containing x to the left, all other terms to the right.

add '-2x' to each side of the equation.

-30 + 5x + -2x = 6 + 2x + -2x

combine like terms: 5x + -2x = 3x

-30 + 3x = 6 + 2x + -2x

combine like terms: 2x + -2x = 0

-30 + 3x = 6 + 0

-30 + 3x = 6

add '30' to each side of the equation.

-30 + 30 + 3x = 6 + 30

combine like terms: -30 + 30 = 0

0 + 3x = 6 + 30

3x = 6 + 30

combine like terms: 6 + 30 = 36

3x = 36

divide each side by '3'.

x = 12

simplifying

x = 12

this should .
