y=12
Step-by-step explanation:
y=2x ,so 2x=8x-x^2
x^2=8x-2x
x^2=6x
x^2/x=6x/x
x=6

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
