Answer:
x=12
Step-by-step explanation:
The two angles make a straight line, which is 180 degrees
10x-20 +6x+8 = 180
Combine like terms
16x -12 = 180
Add 12 to each side
16x-12+12 = 180+12
16x =192
Divide by 16
16x/16 = 192/16
x =12

Answer:
H = 13.67
Step-by-step explanation:
Given:
The the algebraic expression is
![H + \frac{340}{30} = 25](https://tex.z-dn.net/?f=H%20%2B%20%5Cfrac%7B340%7D%7B30%7D%20%3D%2025)
We need to write the above equation for h.
Solution:
![H + \frac{340}{30} = 25](https://tex.z-dn.net/?f=H%20%2B%20%5Cfrac%7B340%7D%7B30%7D%20%3D%2025)
First we divide the fraction part of the equation by common factor 10.
![H + \frac{34}{3} = 25](https://tex.z-dn.net/?f=H%20%2B%20%5Cfrac%7B34%7D%7B3%7D%20%3D%2025)
Subtract both side of the equation by
.
![H + \frac{34}{3}-\frac{34}{3} = 25- \frac{34}{3}](https://tex.z-dn.net/?f=H%20%2B%20%5Cfrac%7B34%7D%7B3%7D-%5Cfrac%7B34%7D%7B3%7D%20%3D%2025-%20%5Cfrac%7B34%7D%7B3%7D)
![H = 25- \frac{34}{3}](https://tex.z-dn.net/?f=H%20%3D%2025-%20%5Cfrac%7B34%7D%7B3%7D)
To write 25 as a fraction with a common denominator, multiply by
.
![H = 25\times \frac{3}{3}- \frac{34}{3}](https://tex.z-dn.net/?f=H%20%3D%2025%5Ctimes%20%5Cfrac%7B3%7D%7B3%7D-%20%5Cfrac%7B34%7D%7B3%7D)
![H = \frac{25\times3}{3}- \frac{34}{3}](https://tex.z-dn.net/?f=H%20%3D%20%5Cfrac%7B25%5Ctimes3%7D%7B3%7D-%20%5Cfrac%7B34%7D%7B3%7D)
![H = \frac{75}{3}- \frac{34}{3}](https://tex.z-dn.net/?f=H%20%3D%20%5Cfrac%7B75%7D%7B3%7D-%20%5Cfrac%7B34%7D%7B3%7D)
![H = \frac{75-34}{3}](https://tex.z-dn.net/?f=H%20%3D%20%5Cfrac%7B75-34%7D%7B3%7D)
![H = \frac{41}{3}](https://tex.z-dn.net/?f=H%20%3D%20%5Cfrac%7B41%7D%7B3%7D)
![H = 13.67](https://tex.z-dn.net/?f=H%20%3D%2013.67)
Therefore the value of H is 13.67.
The difference in the dogs weight from 2 years ago is -0.83
Answer:
So first you do $0.50 x 3 = 1.5
then you add that to $12.00
$12.00 + 1.5 = 13.5
13.5 is the cost of one pizza.
Since they bought 12:
The total cost of the 12 pizza is $162 <== not important
<u>13.5 divided by 8 is 1.687</u>
<u>round 1.56875 to the nearest cent 1.7 = $2</u>
so each slice costs $2
