Nick is a great baby sitter. he makes $9 an hour. julia is an even better babysitter she makes $12 an hour. julia works 6 hours each week. how many hour does nick need to work in order to earn as much money as julia earns in a week

Nick has to work 8 hours

Step-by-step explanation:

Nick makes 9   works x

Julia makes 12  works 6

first find out how much Julia makes you can do that by multiplying 12 by 6 witch = 72

and we know we are trying to find how many hours Nick needs to work to equal Julia so we knew they are equal

so we have 9X=72

we just have to solve...

divide 72 by 9

leaving use with X=8

the mistake in the pattern is that :

b. the decimal point was moved one too many place values each time

the correct pattern could be made by :

b. moving the decimal point to the right the same numbers of place values as the exponents

y < -3

step-by-step explanation:

-3y - 2 > 7

-3y -2 + 2 > 7+2

-3y > 9

-3y/-3 < 9/-3   (change the inequality sign when multiplying or dividing by a negative number)

y < -3
