The answer is C) because it says 12 miles and 3 hours nothing else
30% of number A means
similarly, 40% of number B means
These must be equal, so we have
Multiply both sides by 10 to get
So, you can choose any number for A, and then you multiply it by 4/3 to get B. There are infinitely many solutions to this equation.
I believe the answer is Diane brought 4 pounds of coffee.
Hello!
The Associative Property of Multiplication states the following:
a × (b × c) = (a × b) × c
The equation given in the image above follows the same form:
9 × (5 × 2) = (9 × 5) × 2
Therefore, the given equation must be representative of the Associative Property.
I hope this helps!
Xy = 6
x = 2
2y = 6
y = 6÷2
y = 3
x + y = (2) + (3) = 5
