Marrrta [24]

Answer:

Step-by-step explanation:

t = tutoring and g = grocery store

t + g = 15......t = 15 - g

15t + 9g = 159

15(15 - g) + 9g = 159

225 - 15g + 9g = 159

-15g + 9g = 159 - 225

-6g = - 66

g = -66/-6

g = 11 <===== 11 hrs worked at the grocery store

t + g = 15

t + 11 = 15

t = 15 - 11

t = 4.....4 hrs tutoring

Could someone please help me with this equation, thank you.<br> -8 + x/5 = 12
madam [21]

Answer:

x = 100

Step-by-step explanation:

1. To get rid of the denominator of 5, multiply both sides of the equation to get 5

-40 + x = 60

2. Add 40 on both sides to get the variable x by itself

x = 60 + 40

3. Solve

x = 100
