For absolute values inequalities, you set up two equations:

x - 4 ≤ 7 and x - 4 ≥ - 7

Now, solve like regular by adding 4 to both sides. You are left with:

x ≤ 11 and x ≥ - 3

This translates to:

- 3 ≤ x ≤ 11

Option D is your answer.

You went shopping and found a pair of shoes that were $45.00 on sale for $27.50. what was the percent of decrease of the shoes?

Mandarinka [93]

Percent decrease = (original number - new number) / original number....* 100
= (45 - 27.5) / 45.....* 100
= 17.5 / 45....* 100
= 0.3888 * 100
= 38.9 % decrease <== thats rounded

Write 15 1/4% as a fraction in simplest form

Helga [31]

Rewrite 15 1/4% as 15.25%. To obtain the desired fraction, divide this 15.25% by 100%:

0.1525

This could be reduced to 61/400, which was obtained by first writing 0.1525 as 1525/10000.
