Dakota wants to beat the record for the most runs batted in in a baseball season. This season, he has 32 runs batted in. If he g
m_a_m_a [10]

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.

A shop sells a party hat at x dollars and a mask at y dollars. On a particular morning, 3 hats and 4 masks were sold for $27. In
Aleks [24]

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:

\left \{ {{3x+4y=27} \atop {3x+6y=33}} \right.

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:

\left \{ {{-3x-4y=-27} \atop {3x+6y=33}} \right.\\.....................\\2y=6\\\\y=\frac{6}{2}\\\\y=3

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:

 3x+4(3)=27\\\\3x=27-12\\\\x=\frac{15}{3}\\\\x=5

What is the value of y?<br> O A. 30°<br> OB. 40°<br> O C. 50°<br> O D. 60°
Lera25 [3.4K]
<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
