Hello from MrBillDoesMath!
Answer: 8a
Discussion
:
Let's study the expression:
2(5a - 4a) + 6a
The boldfaced term simplifies to "a" as 5 = 4 = 1. So the expression becomes
2a + 6a
As 2 + 6 = 8, 2a + 6a = 8a.

12. Take the percent you pay (100-the discount) as a decimal and multiply it by the regular price.
Step-by-step explanation:
For finding the price we pay during a sale, we focus on the percent we pay. If 22% off is the sale, then we spend 78% or 100-22-78. We use this percent byb multiplying the price with a decimal. We convert percents into decimals by dividing the percent number by 100. For example, 78% divided by 100 becomes 0.78.
8. Percent off is 22%. We pay 78%=0.78.
45(0.78)=$35.10
9. Percent off is 33%. We pay 67%=0.67.
89(0.67)=$59.63
10. Percent off is 44%. We pay 56%=0.56.
23.99(0.56)=$13.43
11. Percent off is 75%. We pay 25%=0.25.
279.99(0.25)=$70
12. See explanation above.
Depending on the month you were born either 44 or45
6 1/4 = z + 1 5/8
6 1/4 - 1 5/8 = z + 1 5/8 - 1 5/8 Isolate variable
6 2/8 - 1 5/8 = z Least common denominator
4 5/8 = z Simplify
