The | | sign is called a modulus, it means transform any number inside it to positive, so for example |-2| = 2 but |1| = 1.
therefore, -13 + |-7/4| = -13 + 7/4 = -52/4 + 7/4 = -45/4
the last one
Step-by-step explanation:
it is 40/100
Answer:
m ≤ 60 (look at the picture)
Step-by-step explanation:
<em>5 greater than m is no more than 65</em>
m + 5 ≤ 65 <em>subtract 5 from both sides</em>
m + 5 - 5 ≤ 65 - 5
m ≤ 60
All terms have an x so that is a factor.
answer: B. x
Both of the first
8 - N = 22
N - 8 = 22
Represent the difference between a number and 8 is 22 as it is not mentioned that either 8 or the unknown number N is greater so both of the first two represent the difference between a number and 8 is twenty two.
