please help ~~ and if you could, please explain what a constant of proportionality is :)
Answers
Answer:
The answer is D. k=5
Step-by-step explanation:
The constant of proportionality is just the rate the x increases or decreases at. The x is increasing by 5 over time so the COP or rate is 5.
Answer:
The answer is D: K=5
Step-by-step explanation:
The constant of proportionality is the ratio between two directly proportional quantities. Two quantities are directly proportional when they increase and decrease at the same rate. The constant of proportionality k is given by k=y/x where y and x are two quantities that are directly proportional to each other.
So, what you do is that you get the first number, which is 5/25. Simplify it and divided to get it as low as possible, if you do that, you would get 1/5 and 1/5 can also mean 5/1 in these situations. So your basic answer is 5.

Which expression is equal to -0.4(3/2-1/4)?

B. -3/8+1/16
C. -3/5-1/10
D. -3/5+1/10
Answers
Answer:
The answer is D.
Step-by-step explanation:
The answer is D because the result of the -0.4(3/2-1/4) is -1/2 or -0.5. I checked the answers for everyone, they didn't match except for D, which result also ended in -0.5. You could also open parenthesis and solve like that but I like to compare and double check with the results.
