Only one triangle because 70+30+80=180 and 1 triangle has in total 180°
D
First line has y intercept -2 (the blue line)
Second line has y intercept 3 (the red line)
The point where these two lines cross is D
Answer: number 2
Step-by-step explanation: so a supplementary Angle adds up to a 180 angle so it would be number 2 I think.
Answer:
Y = 2/5z-6/5w
Step-by-step explanation:
6W + 5y = 2z
1. Subtract 6W from both sides
2. 5y = 2z-6W
3. Divide both sides by 5
4. y = 2/5z-6/5W
First you make an equation and establish a variable.
x=amount of hours the DJs will charge the same amount
100+21x=150+15x
Now you solve for x and that will get you your answer.
100+21x=150+15x
-21x -21x
100=150-6x
-150 -150
-50=-6x
8.3333...=x
You can round the answer to $8.33
Hope I helped.
