As y varies directly with x, there is a proportionality constant. As x increases by that certain constant, y also increases. We equate:
y = kx
where k = proportionality constant.
Given the condition, y = 5 when x = 4, then we solve for k:
5 = k(4)
k = 5/4 or 1.25
When y = 8, then
8 = (5/4)(x)
x = 8/(5/4) = (8)(4/5) = 32/5 or 6.4 (ANSWER)
Answer:
157.5 miles with 6 gallons
Step-by-step explanation:
105miles / 4gallons = 26.25miles per gallon
26.25miles per gallon * 6miles = 157.5 miles
Answer:
24 seconds
Step-by-step explanation:
The property illustrated in the given statement 5.p = p.5 is commutative property.
<u>Solution:</u>
We have been given an equation as follows:
5.p = p.5
And we have been asked to find the property this statement illustrates.
The answer to the question is, the statement illustrates commutative property.
The commutative property in math comes from the words "commute" or "move around." This rule states that you can move numbers or variables in algebra around and still get the same answer.
Which satisfies the given statement.
