24/r= 36/27
Cross multiply:
36*r= 24*27
⇒ r= 24*27/36= 18
r=18~
w/0.16 = 6.25
⇒ w= 6.25*0.16
⇒ w= 1
w=1~
2÷3 3 goes into 2 0 times so add 0 to make 20 3goes into 20 6 time so the answer is 0.6666666
Answer:
y = dependent variable
k = constant of proportionality or constant rate of change
x = independent variable
Step-by-step explanation:
The equation,
represents a direct variation showing a proportional relationship between variable y and variable x.
y represents the dependent variable
k represents the constant of proportionality or constant rate of change
x represents the independent variable
just as the problem states, multiply the cost (18.10) by 0.15
18.10 * 0.15 = 2.72
the tip was $2.72
