Let the number be x.
4x - 8 =12
4x =12 +8 ( you bring the eight over to the 12, it becomes positive )
4x = 20
x = 20÷4
x = 5
The problem is a basic algebra equation. It translates to 4x - 8 = 12, which can be solved by adding 8 to both sides and then dividing by 4 to get x=5. The answer is 5.
The subject of this question is Mathematics, specifically algebra. To solve this equation, start by translating the problem into a mathematical expression. This can be done as follows: 4 times a number is represented as 4x, then decreased by eight is -8 and the equation equals twelve (12).
Therefore, the equation is 4x - 8 = 12. To solve for x, you can start by adding 8 to both sides of the equation obtaining 4x = 20. Lastly, divide both sides by 4 to find x, which gives x = 5.
Therefore, the number that meets the condition '4 times a number, decreased by 8 equals 12' is 5.

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.
