Mathematics
1 answer:
hammer [34]3 years ago
3 0

Answer:

x = 2

Step-by-step explanation:

Parallel lines divides the transversals in proportion.

Therefore,

\frac{9}{4}  =  \frac{13.5}{x + 4}  \\  \\ 9(x + 4) = 13.5 \times 4 \\  \\ 9(x + 4) = 54 \\  \\ x + 4 =  \frac{54}{9}  \\  \\ x + 4 = 6 \\  \\ x = 6 - 4 \\  \\ x = 2

To find this, I took the 292 average for 4 days and multiplied it by 4. I also took the 220 mile average for 5 days and multiplied it by 5. I then added these two numbers and I got 2268 miles. In order to find the average, I divided the 2268 miles by the 9 total days.
