x = hours
y = his earnings
Answer:
![X= 15](https://tex.z-dn.net/?f=X%3D%2015)
Step-by-step explanation:
Since the angles are equal the equation to solve would be:
![3x + 20 = 5x - 50](https://tex.z-dn.net/?f=3x%20%2B%2020%20%3D%205x%20-%2050)
you will subtract 3x from 5x and get 2x
![20 = 2x -50](https://tex.z-dn.net/?f=20%20%3D%202x%20-50)
subtract 20 from 50 to get 30
![2x= 30](https://tex.z-dn.net/?f=2x%3D%2030)
divide each side by 2
![\frac{2x}{2} = \frac{30}{2}](https://tex.z-dn.net/?f=%5Cfrac%7B2x%7D%7B2%7D%20%20%3D%20%5Cfrac%7B30%7D%7B2%7D)
![X= 15](https://tex.z-dn.net/?f=X%3D%2015)
Hope this helps
Y = kx
Y is the total cost
The number of dvds is x
The cost of each one ($12) is k
y = $12x
Or instead of Y you can but T for total cost
t = $12x
Answer: B. SAS or/and E. HL
Step-by-step explanation:
The two triangles both have a right angle of 90 degrees and two sides that are congruent so, SAS (side-angle-side). It can also be by HL since they both have a hypotenuse (the 2 lines) and one leg (the 1 line) that are congruent to each other.
21.30•4=85.20
