15-3b=63
subtract 15 from both sides
-3b=48
divide -3 from both sides
b= -16
Answer:
In B) y = x/7 , the constant of proportionality is 7.
Step-by-step explanation:
Two quantities X and Y are said to be in proportion if and only if
X = kY or,
,
where k = Proportionality Constant.
Here, 7 is the constant of proportionality. Then,
A . y = 14x
here,
≠ 7
B . y = x/7
here,
= constant of proportionality .
C. y = x
here,
≠ 7
2 1/2
65/26
26*2=52
65-52=13
13/26 = 1/2
