Question

Which of the following are solutions to the inequality - 7x + 14 = -3.6

a) -10
b) 10
c) 5
d) - 5
e) none

Answer 1

The solution to the inequality -7x + 14 = -3.6 is x = 2.5, so the correct answer is c) 5.

Step-by-step explanation:

To find the solutions to the inequality -7x + 14 = -3.6, we first need to isolate the variable x. We can do this by subtracting 14 from both sides of the equation:

-7x + 14 - 14 = -3.6 - 14

-7x = -17.6

Next, we divide both sides of the equation by -7 to solve for x:

x = -17.6 / -7

x = 2.5

So the solution to the inequality is x = 2.5. Therefore, the answer is c) 5.
