Answer:

x = 11

Step-by-step explanation:

- 5(x - 10) =  - 5

- 5 \times x - 10 \times  - 5 =  - 5

- 5x + 50 =  - 5

- 5x = - 5 -  50

- 5x =  - 55

\frac{ - 5x}{ - 5}  =  \frac{ - 55}{ - 5}

x = 11

- 5(11 - 10) { = }^{?}  - 5

- 5 \times 11 - 5 \times  - 10 { = }^{?}  - 5

- 55 + 50 { = }^{?}  - 5

- 5 =  - 5

a water tank holds 992 gallons but is leaking at a rate of 5 gallons per week . a second water tank holds 1,240 gallons but is l
enot [183]

Answer:

62 week

Step-by-step explanation:

What we need is to represent the ratios in expression

For example if we have 992 gallons and the leaking is 5 gallons per week, the expression for the gallons after every week is

992-5x

x is the weeks

And the other case the expressions is

1240-9x

The question is the weeks for the amount being the same, then every equation can be equal to Y and it represent the same amount

992-5x=y

1240-9x=y

in both the y is the same, then

992-5x=1240-9x

992-1240=-9x+5x

-248=-4x

-248/-4=x

62=X

and that is the weeks we need for the amount being the same in both tanks
