Answer:
4(2a ⋅ 5) = (4 ⋅ 2a) ⋅ 5
Step-by-step explanation:
Let A, B and C be the required expression, according to Associative property;
(A+B)+C = A+(B+C)
This shows that no matter the sum of values in parenthesis, it does not alter the values at both sides.
From the given expression, the expression that is equivalent using the Associative Property of Multiplication is 4(2a ⋅ 5) = (4 ⋅ 2a) ⋅ 5
Note that the product of the values in bracket do not affect the final values
4(2a ⋅ 5) = 4(10a) = 40a
(4 ⋅ 2a) ⋅ 5 = 8a ⋅ 5 = 40a
You can see that both expressions gives the same values
The speed of the jet stream is 4.55 miles per hour
Step-by-step explanation:
Distance of one way trip= 3000 miles
The total distance of the round trip= 6000 miles
Total time = 11 hrs
Speed of the plane = 550 miles per hr
Speed = distance/time
= 6000/11
= 545.45 miles per hour
Speed of the plane = 545.45 + speed of the jet stream
550 = 545.45 + speed of jet stream
Speed of jet stream = 4.55 miles per hour
The speed of the jet stream is 4.55 miles per hour
