lorasvet [3.4K]

Answer:

Step-by-step explanation:

-5y + 4 = -11 Get rid of the numbers to get y alone.

-5y +4 minus 4 = -11 minus 4 Here you are removing the 4 from the left

-5y = -15 Now you will have to get rid of the -5

-5y/(-5) = -15/(-5)

y = 3

PLEASE HELP ME!!! THE RIGHT ANSWER WILL GET THE BRAINIEST!

Lina20 [59]

Answer:

$\sf D) \quad s=8 \frac{1}{4}t$

Step-by-step explanation:

t = time (in hours) → this is the independent variable
s = total area cleaned (in square feet) → this is the dependent variable (as the number of square feet cleaned depends on the number of hours worked)

Therefore, if the rate of cleaning is 8 1/4 square feet per hour, the relationship between s and t is:

$\sf s=8 \frac{1}{4}t$

Inessa05 [86]

Answer:

13,200 feet

Step-by-step explanation:

There are 5280 feet in a mile, so multiply 5280 by 2.5

5280*2.5=13,200

So, every Wednesday, she runs 13,200 feet
