Question

Solve the inequality 2.5d+11.4<-1.3d solve the inequality

Answer 1

`d < -3`

Explanation:

Move the constant to the right-hand side and change its sign:

`2.5d < - 1.3d - 11.4`

Move the variable to the left-hand side and change its signs:

`2.5d + 1.3d < 11.4`

Collect like terms:

`3.8d < - 11.4`

Divide both sides of the inequality by 3.8:

`3.8 / - 11.4 = - 3`

Therefore, the answer is d < -3.

Answer 2

d < -3

Explanation:

2.5d+11.4<-1.3d

3.8d+11.4<0

3.8d<-11.4

d < -3

Just isolate and solve for x and remember, what you do to one side, you must do to the other.

Hope this helps!
