Answer: Choice A) y = cx
The 'c' is the constant of variation
For example, if c = 2, then y = 2x is a direct variation. Whatever x is, we double it to get y. As x increases, so does y. As x decreases, then so does y. Both x and y increase/decrease together.
Direct variation equations always go through the origin, and they are always linear. The 'c' plays the role of the slope. You can think of y = cx as y = mx+b where b = 0 in this case and c = m.
8/10 and 48/60 are equivalent because you can see the 48/60 can divide by 8/10 is 6, you just have to see if the larger fraction can divide the smaller one.
7/8 would be 52.5 minutes
Answer:
'Cause he was yummy and cats are ugly.
X = first place....and each place after that is 50 less
so 2nd place would be x - 50 and third place would be x - 100
so ur answers are :
b. x + (x - 50) + (x - 100)
f. 3x - 150 ...u get this when u combine like terms
