Step-by-step explanation:
923/5000
If you put it in your calculator
Answer: 22 /5
-3+7y=5x+2y
Step-by-step explanation:
Subtract 2y from each side
-3+7y-2y=5x+2y-2y
-3 +5y = 5x
Add 5 to each side
5y = 5x+3
Divide each side by 5
y = 5x/5 +3/5
y = x +3/5
Let x = -5
y = -5 + 3/5
y = -25/5 +3/5
y = -22/5
Step-by-step explanation:
Sum/5 = 90
so Sum = 450 which should be divided by 6
450/6 = 75 as the real average.
