Maybe you need to distribute it. -8y + 8
A+B=15 —>A+15=B(plug this into the other equation)
60a+30b=600
60a+30(a+15)=600
60a+30a+150=600
90a+150=600
90a=450
A=5 (plug back in to first equation)
A+B=15
5+B=15
B=10
They have 5 of the Model A and 10 of model B.
Well lets remember that a square has four sides that are all equal.
So if we know one side, we know them all!
And perimeter is all of the sides added up.
Well.. 4 sides that are all 9 meters long? here's the math!
9 + 9 + 9 + 9 = 36
Your coffee shop is 36 meters long
Good Luck! :)
The range of this data is 65 since the minimum is 20 and the maximum is 85(if its counting by 5s) then you just subtract and you have the range.
