Answer:
z = 7.5
Step-by-step explanation:
Given that z is directly proportional to x and inversely proportional to y then the equation relating them is
z = ← k is the constant of proportionality
To find k use the condition when x = 16, y = 5, z = 16, then
k = = = 5
z = ← equation of proportionality
When x = 21, y = 14, then
z = = 7.5
-4(1-x) I think that’s the correct answer
Answer:
What's the question?
Step-by-step explanation:
Consecutive even numbers are represented like this
even numbers are represented like this 2x=even
consecutive even numbers are 2 apart so
the numbers are 2x, 2x+2, 2x+4
so
2x+2x+2+2x+4=162
add like terms
6x+6=162
subtract 6 from both sdies
156=6x
divide both sdies by 6
26=x
the first even number=2x so
26 ties 2=52
second number=2x+2=52+2=54
third number=2x+4=52+4=56
the numbers are 52,54,56
