1/8 + 3/4 = 1/8 + 6/8 = 7/8 (to the right)
1/8 - 3/4 = 1/8 - 6/8 = -5/8 (to the left)

Suppose you can work at most a total of 25 hours per week. Baby-sitting, x, pays $6 per hour and working at the grocery store, y

Andrei [34K]

Answer:

y=7 number of hours at grocery store

x=18 number of hours at baby- sitting

Step-by-step explanation:

According to the information provided.

x is number of hours at baby- sitting

y is number of hours at grocery store

total number of hours worked

1) x+y =25

total earn in a week

2) x*$6 + y* $9 = $171

from equation 1

x+y=25

x= 25-y

we place the above derived equation in equation 2

x*$6 + y* $9 = $171

(25-y)*$6 + y* $9 = $171

(25*6) -6y +9y =171

150+3y=171

3y=171-150

3y=21

y=7 number of hours at grocery store

x= 25-y

x= 25-7

x=18 number of hours at baby- sitting

Solve for t in terms of the other variables. k= 3tm + rs

Lina20 [59]

Answer:

$t=\dfrac{k-rs}{3m}$

Step-by-step explanation:

It's like solving any equation, except we have letters instead of numbers .

k = 3tm + rs {subtract rs from both sides}

k - rs = 3tm {divide both sides by (3m)}

$\dfrac{k-rs}{3m}=t$ {swap sides}

$t=\dfrac{k-rs}{3m}$ m≠0

{m must be ≠0 because you cannot divide by 0. There is no t for m=0}
