Jane earns $10 per hour babysitting she also earned a one time fee of $40 she earns a total of $100 Write and solve and equation to find how many hours Jane worked to $100 total

6 hours

Step-by-step explanation:

Let the number of hours that Jane worked = x

Jane earns $10 per hour babysitting she also earned a one time fee of $40 she earns a total of $100

Using the straight line equation

y = mx + C

y = Total fees that she earned = $100

x = number of hours she worked = ??

C = One time fee = $40

m = Amount paid per hour = $10

Therefore,

$100 = $10 × x + $40

100 = 10x + 40

Subtract 40 from both sides

100 - 40= 10x + 40 - 40

60 = 10x

x = 60/10

x = 6 hours

The number of hours Jane worked to earn $100 total is 6 hours

step-by-step explanation:

the multiplicative inverse of a fraction a/b is b/a. for the multiplicative inverse of a real number, divide 1 by the number. for example, the reciprocal of 5 is one fifth 1/5 or 0.2, and the reciprocal of 0.25 is 1 divided by 0.25, or 4.

54 km / hours

step-by-step explanation:

we need to convert seconds to hours

60 seconds = 1 minutes

60 minutes = 1hour

15 m         60 second   60 minutes

  * *         = 54000 meters/ hour

second     1 minute             1 hour

now we need to convert meters to km

1000 m = 1 km

54000 m       1 km

*   = 54 km / hours

hour               1000m
