Answer:
(40.6) Is the answer
Step-by-step explanation:
| -72 + 32.4| + 18 / 6 * 3
we do the absolute value first. |-72+32.4| = 39.6
then multiplication (following PEMDAS) 6 * 3 = 18
18 / 18 = 1
39.9 + 1 = 40

Answer:
A. (2 x 20) + 5
B. $45
Step-by-step explanation:
I dont know how to explain A. but,
2 x 20= 40
40 + 5 = 45
I know y=5
You would move the constant to the right
add the numbers
then divide both sides by 25 to get
y=5
Answer:
The amount of time that Sarah sleeps is 6<x<8
Step-by-step explanation:
Mathematical inequality is that proposition that relates two algebraic expressions whose values are different. It is a proposition of relation between two different elements, either by greater, lesser, greater or equal inequality, or less or equal.
A compound inequality (or combined inequality) is two or more inequalities joined with or and and.
When two inequalities are joined with and, they are often written as a double inequality.
You know that teenagers should sleep between 8 and 10 hours per night.. Being x the number of hours slept per night, this can be represented by the following double inequality:
8<x<10
If Sarah normally sleeps 2 hours less per night, this indicates that she sleeps between (8-2) and (10-2) hours per night, that is, between 6 and 8 hours. Represented by a double inequality, Sarah normally sleeps:
6<x<8
<u><em>The amount of time that Sarah sleeps is 6<x<8</em></u>
