Answer:
We know that when x= -10, y= -17.
So, if we put those into direct variation "y=kx", we get
-17= k(-10)
k = -17 / -10
Now we put the value of "k" into the formula and we get A (y= 17/10x )
Well, your ratio given is 18 to 4. so multiply both numbers (18 and 4) by some number and you will have an equivalent ratio.
example: if you had 2 times as many people, then an equivalent ratio would be 18*2 to 4*2 = 36 to 8
Answer:
A.
Step-by-step explanation:
Blueberries
7/8 + 8/9 = 1 55/72
1 55/72 x 4 =
1 = 72
72 + 55 = 127
127/72 x 4/1 = 504/288
504/72 = 7/1
7
Even tho 7 isn´t an option I would pick A. because it is the closest
