Answer:
x=75
Step-by-step explanation:
A triangle is 180° in total and the equation was (2x+30)° if you subtract 30 from 180 you get 150 if you divide that by 2 you get 75.
Answer: 2(75) + 30° =180°
Answer:
2 2/7
Step-by-step explanation:
3 3/7 ÷ 3 = 1 1/7, 1 1/7 x 2 = 2 2/7
We have been given an equation
that represents umber of walls, w, that Joe can paint in t hours. We are asked to find the number of hours it will take Joe yo paint 7 walls.
To solve our given problem, we will substitute
in our given equation as:
![7=\frac{3}{2}t-1](https://tex.z-dn.net/?f=7%3D%5Cfrac%7B3%7D%7B2%7Dt-1)
Let us solve for t.
![7+1=\frac{3}{2}t-1+1](https://tex.z-dn.net/?f=7%2B1%3D%5Cfrac%7B3%7D%7B2%7Dt-1%2B1)
![8=\frac{3}{2}t](https://tex.z-dn.net/?f=8%3D%5Cfrac%7B3%7D%7B2%7Dt)
![8\cdot\frac{2}{3}=\frac{2}{3}\cdot\frac{3}{2}t](https://tex.z-dn.net/?f=8%5Ccdot%5Cfrac%7B2%7D%7B3%7D%3D%5Cfrac%7B2%7D%7B3%7D%5Ccdot%5Cfrac%7B3%7D%7B2%7Dt)
![\frac{8\cdot2}{3}=t](https://tex.z-dn.net/?f=%5Cfrac%7B8%5Ccdot2%7D%7B3%7D%3Dt)
![\frac{16}{3}=t](https://tex.z-dn.net/?f=%5Cfrac%7B16%7D%7B3%7D%3Dt)
Therefore, it will take
hours Joe to paint 7 walls.
