Answer:

9 hours

Step-by-step explanation:

Given the equation:

E = 9.25g + 10.50t

E - weekly total, g- number of hours at gas station, t- number of hours at toy store.

Substitute given values into equation and solve for the missing one:

219.75 = 9.25g + 10.5*13
219.75 = 9.25g + 136.5
9.25g = 219.75 - 136.5
9.25g = 83.25
g = 83.25/9.25
g = 9

Sydawna works 9 hours at the gas station

What is the value of p? 10p+5 = 18p-6over 2

MAVERICK [17]

1) we have to subtract by the number 18p from each of your sides
Like: 10p + 5 - 18p
= 18p -3 -180
This gives us: -8p + 5 = -3
Nextly, we have to subtract by 5 on each of your sides
Like: -8p + 5 - 5
= -3 - 5
This gives us: -8p = -8
Now we have divide by the -8 on each of your sides:
Like: -8p ÷ -8
= -8 ÷ -8
Answer: p = 1

I hope it helped you:)
