7(x-2) + 3(x + 2) = 5(x-6)...distribute thru the parenthesis
7x - 14 + 3x + 6 = 5x - 30...combine like terms
10x - 8 = 5x - 30...subtract 5x from both sides
10x - 5x - 8 = -30....add 8 to both sides
10x - 5x = -30 + 8...combine like terms
5x = - 22
x = -22/5 = - 4 2/5 <==

The price of a microwave oven went up from $75 to $90; then went on sale for $57. What is the percent decrease from the original

Arisa [49]

Answer:

The percent decrease of the microwave from the original price to the sale price is 24%

Step-by-step explanation:

1. Let's review the information given to us to answer the question correctly:

Original price of a microwave = $ 75

Mark-up price of the microwave = $ 90

Sale price of the microwave = $ 57

2. What is the percent decrease from the original price to the sale price?

For answering this question we will use the Direct Rule of Three this way:

Price Percentage

75 100%

57 x

75x = 57 * 100

75x = 5,700

x = 5,700/75

x = 76

76 = 100 - 24

The percent decrease of the microwave from the original price to the sale price is 24%
