Answer:

$\frac{1}{3} + \frac{1}{4}$

Step-by-step explanation:

We want to find an expression that has a value of

$\frac{7}{12}$

First option:

$\frac{7}{8} + 4 = \frac{7}{8} + \frac{32}{8} = \frac{39}{8} \ne \frac{7}{12}$

Second option:

$\frac{1}{3} + \frac{1}{4} = \frac{4}{12} + \frac{3}{12} = \frac{7}{12}$

Correct option

Third option

$\frac{6}{8} + \frac{1}{4} = \frac{3}{4} + \frac{1}{4} = 1$

Fourth option:

$2 \frac{1}{12} + 5 \frac{1}{12} = \frac{43}{6}$

The accountant charged $35 for the first hour of work and $23 for each hour after that.He earned a total of$127 how many hours d

dexar [7]

Answer:

He worked a total of 5 hours.

Step-by-step explanation:

The first hour the man makes $35 dollars for the first hour then for the other hours he earns $23 dollars, right? So we start off with 35.

35 = one hour.

35 + 23 = 2 hours . = 58.

35 + 23 + 23 = 3 hours. = 81.

35 + 23 + 23 + 23 = 4 hours. = 104.

35 + 23 + 23 + 23 + 23 = 5 hours. = 127.

We were looking for if the man earned $127 dollars how many hours would be be working.

He'd be working 5 hours.

Hope this helps (:
