5 0

Answer:

(i) x

(ii) x > 2

Step-by-step explanation:

4x - 4 < 8

Add 4 to both sides of the equation , that is

4x - 4 + 4 < 8 + 4

4x < 12

divide through by 4

x

Also

9x + 5 > 23

subtract 5 from both sides , that is

9x > 18

x > 2

3(2.4−1.1m)=2.7m+3.2
telo118 [61]

Hello again!

First, distribute the 3 to the parenthesis, so you get 7.2-3.3m=2.7m+3.2. Next, subtract 3.2 from both sides to get m's on one side. Then you have 4.2-3.3m=2.7m. Next, add 3.3m to both sides so you can solve for m. Now you have 4.2=6m. Then, divide 4.2 by 6, and m=.7

Hopefully this helps! Let me know if you have any questions

    = (4-8)/ (4+4)

    = -4/8
