Answer:
45 3/10 miles per hour
Step-by-step explanation:
Distance travelled by the car = 30 1/5 miles
Time taken = 2/3 of an hour
Average speed = distance travelled / time taken
= 30 1/5 miles ÷ 2/3 of an hour
= 151/5 ÷ 2/3
= 151/5 × 3/2
= (151 * 3) / (5 * 2)
= 453 / 10
= 45 3/10 miles per hour
Average speed = 45 3/10 miles per hour
Answer:
(6+2)/(-4+8)= 8/4= 2
y+2=2(x+8)
y+2=2x+16
y=2x+14

Answer:
The angles are 35, 90 and 55
Step-by-step explanation:
