The answer is 15
From the graph:
Car A traveled 60 miles in one hour
Car B traveled 75 miles in one hour.
Car B travels 15 more miles per hour
W = width
3w + 7 = length
Equation: 3w + 7 + w = 75
Combine like terms: 4w + 7 = 75
Subtract 7 to the other side: 4w = 68
Divide both sides by 4: w = 17
Width = 17
Length = 3(17) + 7, so 58
You're using the commutative property when you swap the order of factors in a multiplication:
and you use the associative property when you regroup the products of more than 2 factors in a different way:
So, you're constantly alternating between associative and commutative. Try to see which property you're using in the first step, and then keep alternating between the two!
The answer to the question is right
Answer: The model predicts 75m
Step-by-step explanation:
The model predicts 75m. The earlier estimate was 1.6km (1 mile) and was close to a given point. The model would only be a good predictor during the sky crane phase of landing.
