Answer:
29 runs are needed to break the record.
Step-by-step explanation:
He has 32 runs batted in.
If he gets 2 runs batted in at each of the last 13 games, he will have:
32 + 2*13 = 32 + 26 = 58
He will have 58 runs batted in.
He will miss the record by 3.
So the record is 61.
He has 32 and will need 61-32 = 29 runs to break the record.
Answer:
Cost of each hat: $5
Cost of each mask: $3
Step-by-step explanation:
Let be "x" the cost in dollars of a party hat and "y" the cost in dollars of a mask.
Set up a System of equations using the information given in the exercise:

You can use the Elimination Method to solve this System of equations:
1. You can multiply the first equation by -1.
2. Then you must add the equations.
3. Solve for "y".
Then:

4. Now you can substitute the value of "y" into any original equation.
5. Finally, solve for "x" in order to find its value.
Then:

<h3>
Answer: B. 40</h3>
For any triangle, the three angles always add to 180
(y+10)+(2y)+(50) = 180
3y+60 = 180 ... combine like terms
3y+60-60 = 180-60 ... subtract 60 from both sides
3y = 120
3y/3 = 120/3 .... divide both sides by 3
y = 40
