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.
819,461 that is the answer
Answer;
X=6
Explanation
1. Find what’s on both sides
6x -9. And 4x +3
2. Turn into equation to do that you need to put a equal sign in between
6x-9=4x+3
3. Solve
6x-9=4x+3
-4x+9 -4x +9
__________
2x=12
— —
2 2
X=6
Explanation for solving you want your numbers on one side and x’s on the other so for positive numbers I subtract and for negative numbers you add, u only have to move one x and 1 number after simplified. Then you take the number (if one ) next to x and divide it on both sides since it’s multiplication. Then you get your answer
