An airplane flew for 4 hours at a speed of x miles per hour (mph), and at (x+10) mph for next 4 hours. What expression can be used to find the total distance covered by the airplane? A. 8x
B. 8x+10

C. 8(x+10)

D. 8x+40

8(x+10)

Step-by-step explanation:

4 + 4 = 8

Just put the (x+10) and the eight together and that's your answer.

Hope this helps.

blue marble is 15 times out of 50 = 15/50 reduces to 3/10

landing on tails is 24 out of 50 = 24/50 reduces to 12/25

to find the probability of both multiply together:

3/10 x 12/25 = 3 x 12 / 10 x 25 = 36/250

if you multiplied the numerator and denominator by 10 you get 360/2500.

the answer is 360/2500
