3. x+100 = 90 alternate interior angles are equal
subtract 100 from each side
x+100 - 100 = 90-100
x = -10
4. 17x+1 = 120 alternate exterior angles are equal
subtract 1 from each side
17x+ 1 -1 = 120 -1
17x = 119
divide each side by 17
17x/17 = 119
x =7
The distance is approximately 703 kilometers.
To travel that in 12 hours, a car has to go at 703/12=58.583 km/h
Step-by-step explanation:
48{x}^{2} {y}^{2} {z}^{2}
Answer:
x = 6.59 hrs = about 6 hours, 35 minutes
Step-by-step explanation:
Adam drives at 85 km / h. Let's set up equivalent fractions to see how long if he drives 560 km.

Cross-multiply:
85x = 560
Solve for x:
560/85 = x
<u>x = 6.59 hrs = about 6 hours, 35 minutes</u>
If all 4 projects take 15 days, then you multiply 15 times 4. Since 15 * 4 = 60, you will have 60 days to complete the 4 projects.
