Mathematics

Answer:

a. 16

Step-by-step explanation:

Triangles = 180 degrees

180 - 80 = 100

100 = (4x - 4) + (0.5x + 32)

4x - 4 + 0.5x + 32 =100

(4x + 0.5x) +(-4 + 32) = 100

4.5x + 28 = 100

4.5x + 28 -28 = 100 - 28

4.5x = 72

4.5x/4.5 = 72/4.5

x = 16

A red car usb traveling 55mph for 206.35 miles how long does it take the car to arrive at is destination
Nataliya [291]

Hi there!

"mph" stands for "miles per hour".

This means that the car travels 55 miles in 1 hour.

To find your answer, you'll need to use the cross product method :

55 miles → 1 hour

206.35 → x

(1 × 206.35) ÷ 55 = x

206.35 ÷ 55 = x

206.35 ÷ 55 = 3.751818...

206.35 ÷ 55 ≈ 3.75


0.75 × 60 = 45 minutes


Your answer is: It takes 3 hours and 45 minutes for the car to arrive at its destination.


There you go! I really hope this helped, if there's anything just let me know! :)
