Answer:
x = 11
y = 43
Step-by-step explanation:
x = small number
y = large number
Set up a system of equations:
y = 10 + 3x
x + y = 54
Solve system by substitution: x + 10 + 3x = 54
4x + 10 = 54
4x = 44
x = 11
x + y = 54
11 + y = 54
y = 54 - 11
y = 43
Total points scored=72(2)+9
=153
Mean=153/7
=21 6/7
=21.9 (3s.f.)
The original price was 640. 50 percent off would be half of the original price, so it is essentially the discounted price times two
320*2=640
2x*x=2x^2
2x*-y=-2xy
3y*x=3yx
3y*-y=3
2*x=2x
2*-y=-2y
-3x*x=-3
-3x*-y=3xy
combine like terms and that is your answer
