Answer:
B. 5
Step-by-step explanation:
We have been given that R varies directly with S. When S is 16, R is 80. We are asked to find constant of variation.
We know that two directly proportional quantities are in form
, where,
k = Constant of variation.
Upon substituting our given values, we will get:




Therefore, the constant of variation is 5 and option B is the correct choice.
Answer:
8x+8?
Step-by-step explanation:
2x+6x=8x
5+3=8
Since 216 is the cube of 6, 64 is the cube of 4 and x^3 is the cube of x, we have

so the expression is the sum of the cubes of 6x and 4
Answer:
The 4th option, 10g + 24 = t
Step-by-step explanation:
It costs 24 dollars per month no matter what.
$10 * the amount of GB you want
Add those two values to get the total cost per month.
In this case you want 5 GB, so substitute the g in the equation for 5. You will get:
10 * 5 +24 = t
50 + 24 = t
74 = t
So it costs 74 dollars per month to get 5 GB.
