1. (5x - 2) + 7x = 12x - 2
2. 6(x - 5) > 22
6x - 30 > 22
6x > 52
x > 52/6
x > 26/3
First of all, in Mathematics, OF usually represents multiplication. And % means over 100. Anyway, the question basically means 75/100 multiplied by the lifespan. According to the question, the lifespan is 18 years. So that will be;
75/100 x 18
1350/100
13.5
So your answer is 13.5 years. Hope i helped. Have a nice day.
