Answer:
a) y=8
b) x= 9
Step-by-step explanation:
a)
y/16= 2/4
y= 16 * 1/2 (cross multiply)
y= 8
b) x/5 = 36/20
x= 5 * 36/20 (cross multiply)
x= 9
3m² = 3 - 8m
0 = 3m² + 8m - 3
0 = (3m - 1 )(m + 3)
m = -3, 0.33

Answer:
Ciera is driving at a faster rate.
Step-by-step explanation:
You calculate speed, by dividing distance by time.
So 18 divided by 24 is 0.75. That is Ciera's speed.
And then to calculate the other person/thing's speed you have to divide 46 by 60 minutes (equal to one hour). The speed calculates to 0.7666666667
Therefore, Ciera is driving faster.
