-12.2z - 13.4z = -179.2

Mathematics
1 answer:
Ede4ka [16]3 years ago
7 0

Answer:

7

Step-by-step explanation:

This is an equation, where we find the value of z. We can simplify the equation.

-12.2z - 13.4z = -179.2

-25.6z = -179.2

Now, to find the value of z, we have to isolate the variable by dividing both sides by -25.6

-25.6/-25.6z = -179.2/-25.6

1z = 7

z = 7

74$ for working 6 hours.what is the hourly pay rate in hours per dollar
fgiga [73]

Answer:

.081 hours per dollar

$12.333 dollars per hour

Step-by-step explanation:

I'm a bit confused whether you just want hours per dollar or also dollars per hour, so I'll answer both.

First, for the dollars per hour, you want to do 74 divided by 6 equals 12 1/3. So each hour you get paid $12.333

Fort the hours per dollar, you do 6 divided by 74 equals .081.
