Can you work this out: 14 x 14?

Answers

The product of the 14 x 14 is 196.

Given that we need to calculate 14 x 14,

To calculate 14 multiplied by 14, you simply multiply the two numbers together.

Here's the step-by-step process:

Start by multiplying the ones digit of the first number (4) by the ones digit of the second number (also 4).

4 x 4 = 16

Write down the ones digit of the result (6) and carry over the tens digit (1).

Next, multiply the tens digit of the first number (1) by the ones digit of the second number (4).

1 x 4 = 4

Add the carried over tens digit (1) to the result.

4 + 1 = 5

Write down the tens digit of the result (5) and carry over any remainingdigits (none in this case).

Finally, multiply the tens digit of the first number (1) by the tens digit of the second number (1).

1 x 1 = 1

Write down the tens digit of the result (1).

Putting it all together, we get:

14 x 14 = 196

Operation:

   14

×  14

------

  56   (4 × 14)

+140  (10 × 14)

------

 196

Therefore, 14 multiplied by 14 equals 196.

Jillian’s school is selling tickets for a play. The tickets cost $10.50 for adults and $3.75 for students. The ticket sales for opening night totaled $2071.50. The equation 10.50a + 3.75b = 2071.50, where a is the number of adult tickets sold and b is the number of student tickets sold, can be used to find the number of adult and student tickets. If 82 students attended, how may adult tickets were sold?

Answers

Given:
b = 82
\
Asked:
a = number of adult tickets sold = ?

Solution:
10.50(a) + 3.47(82) = 2071.50

solving for a:

a= [2071.5-3.47(82)]/10.50

a=168

FINAL ANSWER: There were 168 adult tickets sold.

Answer:

The correct answer would be , a = 168 tickets were sold

Step-by-step explanation:

Cost of adults ticket   = $10.5

Cost of Students Ticket = %3.75  

Sales Totals for opening night = $2071.5

Equation would be  

10.5a + 3.75b = 2071.5

If 82 students attended the the play at that night, it means the value of b would be 82. Thus substituting the value in the above equation, we can find the value of a, which means how many adult tickets were sold.  

10.5a + 3.75(82) = 2071.5

10.5a + 307.5 = 2071.5

10.5a = 2071.5-307.5

10.5a = 1764

a= 168 tickets were sold.
