Is this a real question ?
Answer:
81%
Step-by-step explanation:
First, let's set up 3 equations:
w*0.6 = x
x*1.5=y
y*0.9=z
Now, we can substitute x in the second equation for w*0.6:
w*0.6*1.5 = y
Lastly, we can substitute y in the last equation for w*0.6*1.5:
w*0.6*1.5*0.9=z
w*0.81=z
Therefore, z is 81 percent of w.
Answer: r - 5 = 8
Step-by-step explanation:
From the question, we are informed that Skye ran r laps today at soccer practice while Nadine ran five fewer laps than Skye.
If Nadine ran eight laps at practice, the equation that can be used to find how many laps Skye ran will be:
r - 5 = 8
This means Skye ran 13 laps
