check the picture below.
all angles at point E are right-angles, therefore x + 20 = 90, meaning x = 90 - 20.
Answer:
-21x
I think I did the math and this is what I got.
Average rate of speed is equal to total distance divided by the total time. the total distance is equal to 4.5+7.5, or 12 miles. The total time from 8:00 to 8:48 is 48/60 of one hour. 12*60/48=15 miles per hour
Answer:
Step-by-step explanation:
20 = 8x + 4r can be rewritten in multiple ways.
1. Reduce the coefficients: 5 = 2x + r
or
2. Solve for r: r = 5 - 2x
or
5 - r
3. Solve for x: x = -----------
