I think they are complementary angles but i am not sure
Answer:
1.68 pints
Step-by-step explanation:
First you need to determine how much blue paint she used, then you can determine how much white paint she used. :)
4/5 of 8.4:
4/5 * 8.4 = 6.72 pints
Now we can determine how many pints of white paint she used by subtracting 6.72 from 8.4:
8.4 - 6.72 = 1.68
So she used 1.68 pints of white paint. :) Hope this helped!
Remember that you can do anything to an equation as long as you do it to both sides except divide by zero
so you can add like terms like this
you can add similar things like 1+3 and m+2m and m^2+2m^2 but not unlke things like 1+m or m+m^2
so m+2m=1m+2m=3m so
r-4+6r=3+8r
use commutative property to move numbers around (a+b=b+a)
group like terms
r+6r-4=3+8r
add like terms
1r+6r-4=3+8r
7r-4=3+8r
subtract 7r from both sides
7r-7r-4=3+8r-7r
0r-4=3+1r
-4=3+r
subtract 3 from both sides
-3-4=3-3+r
-7=0+r
-7=r
r=-7
