11 is the answer
hope this helps
X+y=10, x=10-y
4(10-y)+6y=332
solve the next parts yourself
Substitution is to use one variable to express another variable in order to eliminate one variable in the original equation
Slope formula: Change in y over change in x
Change in y: +4
Change in x: +5
Slope: 4/5
Hope this helps :)
Please give brainliest
So is 4 floors / 10 seconds
If you have 60 seconds you can multiple 10 by 6 because 10×6=60
so you also have to multiple 4 by 6
4×6=24
and because it's descending it's 100-24= 76
