The height of the snow was 84 inches in the beginning of the week. it melts at a rate of 0.15 inches per hour. how many hours would it take for the snow to reach 62 inches?

It takes 147 hours for the snow to reach 62 inches.

Step-by-step explanation:

Given:

Height of the snow at the beginning  = 84 inches

Rate at which the snow melts = f 0.15 inches per hour

To Find:

The time taken for the  snow to reach 62 inches = ?

Solution:

Let the time taken to reach 62 inches be x

Then according to the question,

Total height of the snow - (rate of melting)(x) = 62 inches

On substituting the values,

84 - (0.15)(x) = 62

84 - 0.15x = 62

- 0.15x = 62 - 84

- 0.15x = -22

0.15x = 22

x = \frac{22}{0.15}

x= 146.6

x = 147

step-by-step explanation:

just plug in each number for x and see which ones work and don't

-13

step-by-step explanation:

f(x)=2x-5 for f(-4)

f(-4)   means let x=-4

f(-4) = 2(-4) -5

f(-4) =-8-5

      = -13
