Answer:
1 4/5 or 1.8 pints are white
Step-by-step explanation:
1/4 of 7 1/5 = 1/4 x 36/5 = 36/20 or 9/5, which is 1 4/5
Linear combination method just means to add the equations so that one variable with cancel. In this case the a values are already set up so that they will cancel.
2a + 3b = 1
-2a + b = 11
4b = 12
b = 3
now put 3 back into either of the original equations and solve for a.
2a + 3(3) = 1
2a + 9 = 1
2a = -8
a = -4
(-4,3)
5 obtuse no acute and no right
