jerry is a judge. He hears 5 cases every 2 3/8 hours. Jerry hears caese at a constant rat. How many cases does he hear per hour
faust18 [17]

Answer:

The number of cases heard by Jerry per hour is 2\frac{21}{500}

Step-by-step explanation:

The rate of hearing the cases is 5 cases in 2 3/8 hours.

Now, 2\frac{3}{8}   = 2+\frac{3}{8}  = 2 + 0.375 = 2.375

⇒The judge hears 5 cases in 2.375 hours.

So, the number of cases per hour = = \frac{\textrm{Total Number of cases heard}}{\textrm{Number of Hours}}  = \frac{5}{2.375}

                                                           = 2.105

Also, 2.105 =   2 + 0.105 =  2 + \frac{105}{1000}   = 2+\frac{21}{500}  = 2\frac{21}{500}

Hence, the number of cases heard by Jerry per hour is 2\frac{21}{500}

Solve the system of equations.<br> - 5x – 3y - 9 = 0<br> 4x – 187 - 54 = 0
liberstina [14]

Answer:

Step-by-step explanation:

Solve simultaneously

-5x-3y=9

4x-187-54=0

4x=241

x=60.25

To get y

Substitute for x in equal one

-5(60.25)-3y=9

-301.25-3y=9

-3y=9+301.25

-3y=310.25

y=-103.4
