Answer:
Step-by-step explanation:
The ratio is 12/8 or 3/2
So we can use proportions
3/2=x/15
x=22.5
180 degrees. in an equilateral triangle, each angle is 60 degrees
Answer: D
Step-by-step explanation:
You need a calculator for this cause the numbers are really large. I used a fx-9860GII Casio calculator. I put the equations on the graph mode. And then I got the x➡️0 for both equations.
I got x=0, y=5000 for the first equation
x=0, y=5200 for the new one.
You can see the y is (5200-5000)=200 more than the old equation. As the x is 0 for both that means the new one moved 200 up for the new one. It goes up cause its positive number .
I put the pictures so you can understand what I'm saying.
Answer:
17. 10x+24 OR 108 18. 72 19. 8.4
Step-by-step explanation:
(10x+24)+72=180
10x+96=180
10x=84
x=8.4
10x+24
10(8.4)+24
84+24
108
