Step-by-step explanation:
3( x +1) = 5 (x - 2) + 7
3x + 3 = 5x - 10 + 7
5x - 3x = 3 + 10 - 7
2x = 13 - 7
2x = 6
Therefore x = 3
60 * 2 = 120
120 / 45 = 2.6...7
2.6 * 45 = 29.3... (3 repeating) mi.
Messed that up!
11 / 45 = .24...
.24 * 120 = 28.8<u />
Answer:5.9-6.2x
Step-by-step explanation:
a=1.4-2x
b=-0.2x+1.7
3a+b
=3(1.4-2x)+(-0.2x+1.7)
=4.2-6x-0.2x+1.7
=4.2+1.7-6x-0.2x
=5.9-6.2x
It's factorable when c ∈ {5,8,9}
