Final answer:
To find what percent 5x is of 8x, calculate (5x / 8x) * 100% which gives 62.5%. To find 65% of 80x, multiply 80x by 0.65, resulting in 52x.
Step-by-step explanation:
To answer these questions, we can use simple percentage calculations and apply them to the algebraic expressions provided.
a. What percent of 8x is 5x?
To find out what percent 5x is of 8x, we can set up the equation (5x / 8x) * 100%. Simplifying 5x / 8x gives us 5/8, and multiplying this fraction by 100% gives us the percentage.
(5/8) * 100% = 62.5%
So, 5x is 62.5% of 8x.
b. What is 65% of 80x?
To find 65% of 80x, we can multiply 80x by 0.65.
65% of 80x = 80x * 0.65 = 52x
Therefore, 65% of 80x is 52x.
