Answer: see below

Step-by-step explanation:

The charges is always at least $80 just for the plumber to show up. The, it increases by $60/hour.

We represent cost, c in dollars, as below.

part A -->  c = 80 + 60h

where h is the number of hours.

For 3 hours work, c = 80 + 60(3) = 80 + 180 = $260

part B -->  $260

I hope this helps.

-1 3/5 divided by (-2/3) write as mixed number
hichkok12 [17]

Step-by-step explanation:

- 1  \frac{3}{5}  \div  \frac{ - 2}{3}

Convert the mixed numbers above to improper fractions. Thus:

\frac{ - 8}{5}  \div   \frac{ - 2}{3}

In order to simplify the fractions above, the division sign changes to multiplication sign thus turn the right hand side of the fraction inversely such that -2/3 to -3/2. Hence,

\frac{ - 8}{5}  \times  \frac{ - 3}{2}

\frac{ - 8 \times  - 3}{5 \times 2}

=  \frac{24}{10}

= 2  \frac{4}{10}

= 2  \frac{2}{5}

Bao saved $179 a month. He saved $145 less than Ada each month. How much would Ada save in three and a half years?
IgorC [24]
If i am correct, the answer should be 13608.
To find out how much Ada saved a month, we would need to add 179 and 145, that equals 324. Then we would need to multiply that by 12 because there are 12 months in a year. We would get 3888. Then we would need to multiply that by 3, since there are 3 years. We would get 11664. Then we would need to multiply 324 and 6 for 324 dollars a month. That gives us 1944. Then we add 1944 and 11664, we get 13608. :)
