Aplumber charges $13.50 per hour for a plumbing job that requires more than 3 hours to complete . for any job requiring 3 hours or less , there is a flat charge of $40.50 . if h represents the number of hours the job requires , which of the following equations gives the charge 1) 13.5h+40.5=t. 2) t=13.5h. 3) 13.5h-40.5=t. 4) 40.5=t

Equations 2 and 4?

Step-by-step explanation:

It sounds like there are two separate equations for this problem depending if the time spent on the job is more, or less than or equal to 3. If the job is more than 3 hours the equation would be number 2. If the job takes less or equal to three hours the equation would be 4. I hope this helps.

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

answer: -2+√x,-2-√x

i hope this , i don't know if you're looking for a pair or not.
