Answer:

2 months

Step-by-step explanation:

you can set up equations for each sister:

(Sarah) y = 3x + 30

(Anna) y = -2x + 40

you can graph them to find where they intersect (2,36) or:

you can set them equal to each other like the following:

3x + 30 = -2x + 40

5x = 10

x = 2

-5(3m + 6) = -3(4m - 2)

-15m - 30 = -12m + 6

-30 = -12m + 6 + 15m

-30 = 3m + 6

-30 - 6 = 3m

-36 = 3m

-36/3 = m

-12 = m

hope this helps, God bless!

X is 19
Explanation: because the opposite side of the angle is 134 degrees the other side also has to be 134 degrees. So we do 134-20 which is 114 and then 114 divided by 6 because the number next to x is 6 and the number that is x has to be 19 as 19x6 is 114.
I think this is the right answer and I hope it helps :)

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.
