For a direct variation, f(x) = kx. Therefore, for f(x) = 30x, constant of variation (k) = 30.
Step-by-step explanation:
from,
An = 4n -13
A1 = 4 (1) - 13
> A1 = -9
A2 = 4(2) - 13
> A2 = -5
A3 = 4(3) - 13
> A3 = -1
A4 = 4(4) - 13
> A4 = 3
Answer:
43%
Step-by-step explanation:
(40-70) ÷ 70 = -30 ÷ 70 = -0.43 or -43%
Answer: The video game was reduced by 43%.
We know that 12 equals one dozen. It is not asking for a dozen, but for 9 dozen. So, we need to multiply 9 by 12. 9*12 = 108.
It says the rolls of first aid tape were divided equally into 4 boxes. We need to divide these 108 rolls into 4 equal groups, since that is what took place in the problem. So, we divide 108 by 4.
108/4 = 27. There are 27 rolls in each box.
I’m pretty sure the answer would be B
