To find the average add all the numbers together then divide by how many numbers there are.

75+80+97+92=344 divided by 4 = 86

So her average right now is 86.

She’d have to make 96 to get an average of 88.

75+80+97+92+96=440 divided by 5=88

The answer is 96

Two consecutive integers have a product of 132.Find the integers
maksim [4K]
The difference between consecutive integers is 1.
Let x = smaller integer.
Then x + 1 is the next greater consecutive integer.

x(x + 1) = 132

x^2 + x - 132 = 0

(x + 12)(x - 11) = 0

x + 12 = 0   or   x + 11 = 0

x = -12   or   x = -11

Since x is the smaller of the two integers, the answers are:
-12, -11
11, 12
There are two pairs of such integers.

Answer:
x = 7


General Formulas and Concepts:
Order of Operations: BPEMDAS


Step-by-Step Explanation:
Step 1: Define
5(x - 3) = 2(x + 3)

Step 2: Solve for x
1. Distribute: 5x - 15 = 2x + 6
2. Subtract 2x on both sides: 3x - 15 = 6
3. Add 15 on both sides: 3x = 21
4. Divide both sides by 3: x = 7
