Answers

Answer: There were 89 retail stores in 1997.

Step-by-step explanation:

Hi, to answer this question, first, we have to calculate the number of years since 1990(x).

1997-1990 = 7 years

Now, we simply substitute x=7 (years) in the equation given

y=11x+12

y=11(7)+12

y=77+12

y = 89 retail stores

There were 89 retail stores in 1997.

What is the value of 7/8 +3/4

Answers

Find the common denominator:

7/8+6/8
= 13/8 or $1 (5)/(8)$

Since 3/4 equals 6/8, you do 7/8 + 6/8 = 11/8 and that can be simplified to 1 and 3/8 and put into decimal form like 1.375.
