42 x 1.07 = 44.94
44.94 - 2.94 = 42
58 x 1.07 = 62.06$
Answer:
x=26
y=9
Step-by-step explanation:
5x-17+3x-11=180
8x=180+17+11
8x=208
x=26
3(26)-11=78-11=67
2y+5=90-67
2y=90-67-5
2y=18
y=9
1. 4n - 6n - 6 > 12
-2n > 18
n < -9.
2. 5 > 5(12-a)
5 > 60 - 5a
5a > 55
a > 11
3. 2s + 20 < 119 - 9s
11s < 99
x < 11
9(3x - 9) - 7 - 2x
27x - 81 - 7 - 2x expand
(27x - 2x) + (-81 - 7) collect like terms
25x - 88
hope this helped, God bless!
