According to the rule of 72, that rate will be 72/33 ≈ 2.18 percent.
No, this rel. is not proportional because of the addition involved ("plus 1 lb for each guest").
A proportional rel. features mult. only.
Answer:
His distance walked is 13 km
Calvin's displacement is 5 km south and 8 km east.
Step-by-step explanation:

Answer: The value of x is 1
Step-by-step explanation:
10x + 5 = 15
Collect the like terms which in this case are the whole numbers "5" and "15")
10x = 15 - 5
10x = 10
Divide both sides by 10
10x/10 = 10/10
x = 1
Thus, the value of x is 1
Answer:
Step-by-step explanation:
The question and the attached image are different. However, the attached image answers the question y = -4 correctly.
So, I will solve for: 
Given
Required
Possible values of x and y
Let x = 0:
So, we have:
Let y = 4
Collect Like Terms
So, we have:
<em>So, all you need to do is: assume a value for either x or y, then solve for the other variable.</em>
