Answer: 6 hours : 1 book
A unit rate is a rate expressed as a quantity of 1
Answer:
-4
Step-by-step explanation:
Wehn dealing with order of operations, we can remember the expression PEMDAS, which stands for parentheses, exponents, multiplication, division, addition, and subtraction.
So, our first step in the above problem is the parentheses:
![2(3-5)^3+4(-4+7)\\2(-2)^3+4(3)](https://tex.z-dn.net/?f=2%283-5%29%5E3%2B4%28-4%2B7%29%5C%5C2%28-2%29%5E3%2B4%283%29)
The second step is exponents:
![2(-2)^3+4(3)\\2(-8)+4(3)](https://tex.z-dn.net/?f=2%28-2%29%5E3%2B4%283%29%5C%5C2%28-8%29%2B4%283%29)
The third step is multiplication:
![2(-8)+4(3)\\-16+12](https://tex.z-dn.net/?f=2%28-8%29%2B4%283%29%5C%5C-16%2B12)
The fourth and final step is addition:
![-16+12\\-4](https://tex.z-dn.net/?f=-16%2B12%5C%5C-4)
Your answer is 1.5 if you multiply 15 by 10% you get 1.5 and if you ivide 1.5 by 10% you get 15 so you can find your answer and check it
hope this helps have a nice day.
Answer: x < -2.861353
Step-by-step explanation:
simplify to: 0.69897x <-2
divide both sides by 0.69897
0.69897/0.69897 < -2/0.69897
so the answer is x < -2.861353
<em>Answer: x = 5</em>
<em>Step-by-step explanation:</em>
