Answer:
the same as multiplying them, except you're doing the opposite: subtracting where you would have added and dividing where you would have multiplied. If the bases are the same, subtract the exponents. Remember to flip the exponent and make it positive, if needed.
Step-by-step explanation:
6.5c + 9.7a = 1721.4
a = 4c
6.5c + 9.7(4c) = 1721.4
6.5c + 38.8c = 1721.4
45.3c = 1721.4
c = 1721.4 / 45.3
c = 38...so there were 38 childrens' tickets <==
and 152 adult tickets
The answer should be the first one exponential
Answer:

Step-by-step explanation:
The formula of an area of a rectangle:

l - length
w - width
We have

Substitute:
<em>divide both sides by 15</em>

The formula of a perimeter of a rectangle:

Substitute:

Answer:
J=38
Step-by-step explanation:
Subtract 7 to both sides so J/-2=-19
Then multiply -2 to both sides to get -19 times -2
That equals to 38
