Step-by-step explanation:
I think the correct answer from the choices listed above is the last option. The axiom that allows x(10) to be written 10x would be the commutative property of multiplication. It states that numbers can be added or multiplied in any order. Hope this answers the question. Have a nice day.
First, assign two variables to the prices of the two appliances.
'w' will represent the price of a washer, and 'd' will represent the price of a dryer.
Because "the washer is three times the cost of the dryer," we can form this equation:
w = 3d
On top of that, we know the washer and dryer add up to 600, making another equation.
w + d = 600
Because we know the value of 'w,' we can input that into the equation 'w + d = 600'
(3d) + d = 600
Simplify:
4d = 600
d = 150
Since the washer is three times the price of the dryer:
w = 3(150) = 450
The dryer costs $150, and the washer costs $450.
