1. 17
4. 11 2/5
7. 45 15/16
So we have two quantities and need to find out how much percentage it increased from one to another and then maybe write an equation that describes the behavior. Lets find the percentage raise between quantities using a simple rule of three, direct proportion:
<span>150 -----> 100</span>
162 ----> x
x = (162)(100)/150
x = 108
that means that $162 is the 108% of $150, or that the tickets are raising their price by 8% daily. The problem states as well that the price grow is exponential, not expressed by a linear equation that is.
Answer:
L = 15, W = 8
Step-by-step explanation:
Perimeter = 2(L + W)
P = 40
L = 2W - 1
40 = 2((2W-1) + W)
40 = 4W - 2 + 2W
40 = 6W - 2
42 = 6W
W = 8
Since L = 2W - 1
L = 2(8) - 1
L = 15
15 x 4 = 60
60 min in an hour
So 10 x 4 = 40

Answer:
c = 2s + 3
Step-by-step explanation:
Let <em>c</em> be Carly's age.
Carly is 3 more . . . than twice her sister's age.
We can translate "twice her sister's age" into <em>2s</em>.
Carly is 3 more than 2s.
We can translate this into:
Carly is 3 + 2s.
c = 2s + 3
