X and y are the times in hours that he travelled on foot and on bus
x + y = 1.5 * by 5:-
5x + 5y = 7.5
5x + 60y = 35 subtract:-
55y = 27.5
y = 0.5
and x = 1.5 - 0.5 = 1
so he walked for 1 hour
distance he walked = average speed * time = 5*1 = 5 miles.
Answer:
A, D
Step-by-step explanation:
When solving for x, we want to get all x terms on one side and all non-x terms on the other side. To make it so that x is by itself, we need to get rid of -3. We can do this by adding 3 to both sides, which demonstrates the addition property of equality. This property states that if you add a quantity to one side of an equation, you must add the same quantity to the other side as well.
