C, I’m pretty sure
Why do I have to write 20 words for this? This is why I’m rambling.
I believe the answer is 0.9 because a significant figure is a similar difference
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.
2 less than (3 times a number) is the same as (the number plus 10)
2 less than (3*x) = (x + 10)
3x - 2 = x + 10
From here, you solve! :)
3x - 2 - x = x + 10 - x
2x - 2 = 10
2x - 2 + 2 = 10 + 2
2x = 12
2x / 2 = 12 / 2
x = 6
Hope this helps! :)
