Answer:75 mph
Step-by-step explanation:
To start off, you want to make the equations. first, we will make x = chocolate candy and y=caramel candy since thats the order they come in the problem. we know she bought 20 pieces of candy, so we now know our first equation, x+y=20. next, if each chocolate candy costs $.50, that now makes x in our second equation .5x. the y will then be .1y. they then total up to equal $6.80, so our second equation is .5x+.1y=6.8. to then find x, subtract the y from the first equation to get x=20-y. then in the second equation, replace x with y and solve. you then get y=8, so we know britney has 8 caramels. now in the first equation, replace the y to get x+8=20. and now x=12
Answer:
f = 59
g = 59
Step-by-step explanation:
f = 180 - 121
f = 59
g = 180 - 121
g = 59
B = 0.5A + 30
C = 1.5A + 20
If B = C, that means we can set the two equations equal to each other.
0.5A + 30 = 1.5A + 20
A = 10... Plug that into one of the equations to find B or C (they are the same)..
B = 0.5 * 10 + 30 = 35
35 + 35 + 10 = 80 total.
