Answer:
Step-by-step explanation:
1 11\16
Answer: 4h/5
Step-by-step explanation:
1x30, 6x5, 3x10, 15x2 here are some.
4x - 3y = 3...multiply by 4
5x - 4y = 3...multiply by -3
--------------
16x - 12y = 12 (result of multiplying by 4)
-15x + 12y = - 9 (result of multiplying by -3)
---------------add
x = 3
4x - 3y = 3
4(3) - 3y = 3
12 - 3y = 3
-3y = 3 - 12
-3y = - 9
y = -9/-3
y = 3
solution is (3,3).....and the x = 3
$60 + (60 · 0.20) = 60 + 12 = 72
$72 - (72 · 0.20) = 72 - 14.4 = 57.6
Answer: $57.60
