The additive inverse of something is just what the certain number needs to equal 0. In this case 3+5=8 inches total. In order to get 8 inches to 0 you need to add -8 to 8. So the additive inverse is -8 inches (Always remember your units, in this case inches) Hope this helped :)
12×47=12×(50-3__)
=(12×50__)-(12×3)
=600-_36_
=564_
I believe this is your answer is I understand correctly.
(1/x^3)/(3/x^2)=x^2/3x^3
x^2/3x^3=1/3x
Answer:
The value of given expression is 3.8.
Step-by-step explanation:
Given:
![1.8+0.5(y+6)-2^3](https://tex.z-dn.net/?f=1.8%2B0.5%28y%2B6%29-2%5E3)
We need to find the simplified value of given expression using y =14
Solution:
Now we will substitute y =14 we get;
![1.8+0.5(y+6)-2^3\\\\1.8+0.5(14+6)-2^3](https://tex.z-dn.net/?f=1.8%2B0.5%28y%2B6%29-2%5E3%5C%5C%5C%5C1.8%2B0.5%2814%2B6%29-2%5E3)
Now using PEDMAS we will first solve the parenthesis we get;
![1.8+0.5\times20-2^3](https://tex.z-dn.net/?f=1.8%2B0.5%5Ctimes20-2%5E3)
Now we will solve the exponent function we get;
we know that;
![2^3=8](https://tex.z-dn.net/?f=2%5E3%3D8)
So we can say that;
![1.8+0.5\times20-8](https://tex.z-dn.net/?f=1.8%2B0.5%5Ctimes20-8)
Now we will solve the multiplication operation.
![1.8+10-8](https://tex.z-dn.net/?f=1.8%2B10-8)
Now we will perform addition operation.
![11.8-8](https://tex.z-dn.net/?f=11.8-8)
And finally we will perform subtraction operation.
3.8
Hence The value of given expression is 3.8.
1) Subtract the base fee
360-60=300
2) Divide the total by the hourly pay
300:30=10
