Question 135 I feel ashamed that i dont know maf or how to spel

k = 3

Step-by-step explanation:

=> 4.5 + 1.5 k = 18 - 3k

=> 1.5 k + 3k = 18 - 4.5

=> 4.5 k = 13.5

Dividing both sides by 4.5

=> k = 3

k = 3

Step-by-step explanation:

4.5 + 1.5k = 18 - 3k

Add 3k to both sides.

4.5 + 4.5k = 18

Subtract 4.5 from both sides.

4.5k = 13.5

Divide both sides by 4.5

k = 3

x > 1.3

step by step:

8.5−0.9x> 9.8−1.9x

step 1: simplify both sides of the inequality.

−0.9x+8.5> −1.9x+9.8

step 2: add 1.9x to both sides.

−0.9x+8.5+1.9x> −1.9x+9.8+1.9x

1x+8.5> 9.8

step 3: subtract 8.5 from both sides.

1x+8.5−8.5> 9.8−8.5

1x> 1.3

step 4: divide both sides by 1.

1x/1 > 1.3/1
