Answer:
The answer is b = ax- c/x
when i put the / it means fraction
Supplementary=add to 180. U/V=7/13, U+V=180. Solving, U=63 and V=117
15/100
Im pretty sure thats the answer :3
Answer:
D = 12 Miles from her house to Fixit.
Step-by-step explanation:
Speed =Distance travelled/ Time
Time =Distance travelled/ Speed
T = D / 30 The time it took her to drive to Fixit.
T = D / 20 The time it took her to ride the bus home.
D / 30 + D / 20 = 1 hour, solve for D,
Let candy bars =xLet drinks =y Set up the two equations. 60x + 110y = 265120x + 90y = 270 Solve through elimination. Multiple the first equation by 2 and subtract the second equation from the first. When we multiply the first equation by two, we get: 2(60x +110y = 265) = 120x + 220y = 530 Then, when we subtract the second from the first we get: (120x + 220y = 530) - (120x +90y = 270) The result is 130y = 260 So, y=2 Then, we plug that back in to the original equation to find x. 60x + 220 = 265 Subtract 220 from both sides. 60x = 45 x = .75 So, drinks cost 2 dollars and candy bars cost 75 cents.
Hope this helps! :)
