Answer:
Step-by-step explanation:
You are given GALLONS and MILES
you want to find MILES / GALLON
so just put those numebrs in
MILES / GALLON = 126 miles / 6 gallons = 21 m/g (or 21 MPG)
Yes..The answer s D. because the circles are congruent and in the question, it stated that it wanted circles that were similar, not congruent
Let a=price of adult ticket
let c=price of a child's ticket
start out by writing the following system of equations:
3a+4c=132
2a+3c=94
then, multiply the first equation by 2, and the second equation by 3 to get the following system of equations:
6a+8c=264
6a+9c=282
subtract the like terms to get the following equation:
-c=-18
divide both sides by -1 to get rid of the negative to get the price of a child's ticket to be $18. to find the price of an adult ticket, pick one of the original equations to substitute the 18 in for c to find a. for example:
2a+3c=94
2a+3(18)=94
2a+54=94
-54 -54
2a=40
2 2
a=20
or if you decide to use the other equation:
3a+4c=132
3a+4(18)=132
3a+72=132
-72 -72
3a=60
3 3
a=20
either way, you still get an adults ticket to be $20 and a child's ticket to be $18.
223,200,000 should be correct
