Question

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

Answer 1

Answer:

$d < -3$

Step-by-step 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:

$3.8 \div - 11.4 = - 3$

Therefore, the answer is d < -3.

Answer 2

Answer:

d < -3

Step-by-step 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!
