Answer:
5(2x+6x) and 10(x+3x)
Step-by-step explanation:
because the three results 40x
Answer: See explanation
Step-by-step explanation:
a. Determine the unit rate for the number of laps she can run per minute.
This will be calculated as the number of minutes used divided by the number of laps which will be:
= 25 / 10
= 2.5 minutes per lap.
b. Find the constant of proportionality for this situation.
We will use the formula y = kx
where y = 25, x = 10, k = constant of proportionality.
Therefore, y = kx
25 = 10k
k = 25/10
k = 2.5
The constant of proportionality is 2.5
Solve the second equation for 
, then substitute it into the first equation.
Answer:
I know this one!!!
Step-by-step explanation:
Take the x value and multiply it by the y value to get a number. In this case, xy=60. That is the inverse equation. (15/8) times 32 is 60.
You can also take 60 and divide it by 32 to get (15/8)
