X=40 degrees
100+2x=180
80=2x
x=40
Step-by-step explanation:
18.029= (1×10)+(8×1)+(2×1100)+(9×1100)
From the beginning we know we are dealing with two different rates. Distance is equal to (Speed X Time). We have two different speeds though. We will call the min speed = x and the max speed = y. With those two ideas in place we can make two equations for both Tony and Rae.
Tony:
2x+3.5y=355
Rae:
2x+3y=320
Now you can solve the equations by subtracting Rae's equation from Tony's
.5y=35 solve for y and you get 70
Now plug that y value back into either equation and you can solve for x. I'll use Rae's distance:
2x+3(70)=320
x=55
Answer:
x = 114
Step-by-step explanation:
180 - 105 = 75
39 + 75 = x
x = 114
