translate the sentence into a equation using n as the unknown number . Then solve the equation for n . 5 increased by half a number is 11

I think it'll be 5 + n = 11

11 - 5 = 6

n = 6

Below in bold.

Step-by-step explanation:

Let the number be n, then:

5 + 1/2n = 11

1/2n = 11 - 5

1/2n = 6

Multiply both sides of the equation by 2:

n = 12.

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
