Answer: Option B.
Step-by-step explanation:
If a varies directly with b then when a increases b it also increases by a factor k.
Then we can write that
We know that when a = 28 then b = 7. So
Therefore the equation of proportionality is:
So when then:

Answer:
<h3>
TRUE</h3>
Step-by-step explanation:
In arithmetic sequence the difference (d) between any pair of next and previous term is the same.
-7-23 = - 30
-37 - (-7) = -37+7 = - 30
-67 - (-37) = -67 +37 = - 30
d = -30
So this is arithmetic sequence.
72÷9= 8
9×8=72
63+72+8-13
72+8=80
63+80= 143
143-13= 130
