Answer:
Option 1 - 
Step-by-step explanation:
Given : The goals against average (A) for a professional hockey goalie is determined using the formula
. In the formula, g represents the number of goals scored against the goalie and t represents the time played, in minutes.
To find : Which is an equivalent equation solved for g?
Solution :
Solve the formula in terms of g,

Multiply both side by t,

Divide both side by 60,


Therefore, option 1 is correct.
1 - 3x = x + 3 |subtract 1 from both sides
-3x = x + 2 |subtract x from both sides
-4x = 2 |divide both sides by (-4)
x = 2/-4
x = -0.5
Answer:
There are 8 possible combinations.
Look at this example:
2 sandwiches: PB&J, turkey sandwich
4 drinks: soda, water, lemonade, tea
1 dessert: cake
all 8 combos:
- PB&J, soda, cake
- PB&J, water, cake
- PB&J, lemonade, cake
- PB&J, tea, cake
- turkey sandwich, soda, cake
- turkey sandwich, water, cake
- turkey sandwich, lemonade, cake
- turkey sandwich, tea, cake
hope this helps
