Total = amount Amy has(A) + amount Ruben has(R) + amount Sam has(S)
S = 3 * R
R = A + 9
S = 3 * (A+9)
S = 3A + 27
71 = A + (A + 9) + (3A + 27)
71 = 5A + 36
5A = 35
A = $7
R = A + 9
R = 7 + 9
R = $16
S = 3 * R
S = 3 * 16
S = $48
Answer: $8.25 is your answer.
Step-by-step explanation:
12 x 3 = 36
2.75 for 12 so 2.75 times 3 = 8.25
So I drew a number line , & I placed point e at 1 1/4 . The correct answer will be B . It couldn't be A because if point e was 1/4 to the left of 1 , point e will be located at 3/4 . But because it ask to put point e at 1 1/4 , you would look for 1 & just move up 1/4 .
Answer:
t = 5 seconds
Step-by-step explanation:
We have,
Speed of the truck, v = 4 m/s
It is required to find the time taken by a truck to travel 20 meters. It can be assumed that the time is t. Using the formula of speed.

After rearranging, we get :

So, the time taken by a truck to travel 20 meters is 5 seconds.
Answer:
256 train or 80% of the trains arrived on time
Step-by-step explanation:
Total trains that arrived in a week = 320 trains
Late = 5% of 320
early = 15% of 320
On time = 320 - (15 + 5% of 320)
=> 320 - (20% * 320)
=> 320 - 64
=> 256
Therefore, 256 train or 80% of the trains arrived on time
Hope my answer helps :)
