After a 2 1/2 hour rainstorm, there are 5 inches of water in a bucket outside. What is the rate per inch?

xeze [42]

Answer:

2 inches per hour

Step-by-step explanation:

2 1/2 hours is equivalent to 150 minutes.

Set up a proportion; let x equal inches of rain

$\frac{5}{150}$ = $\frac{x}{60}$

Cross multiply -> 150x=300

Divide both sides by 150 to get -> x=2

Fifteen more than half a number is 9

rusak2 [61]

For this case, the first thing we must do is define a variable.

We have then:

x: unknown number

We now write the equation that models the problem:

$(\frac{1}{2}) x + 15 = 9$

From here, we clear the value of x.

We multiply both sides of the equation by 2:

$(\frac{2}{2}) x + 2 (15) = 2 (9)\\x + 30 = 18$

We subtract 30 on both sides of the equation:

$x + 30 - 30 = 18 - 30\\x = -12$

Answer:

The value of the unknown number is given by:

$x = -12$
