Hailey sold 20 tickets to the school play for a total of 225$.Early bird tickets were 10$ and regular priced tickets were 15$.Wr

dlinn [17]

Answer:

The system of equation are $\left \{ x+y=20} \atop {10x+15y=225}} \right.$

The number of early bird tickets are 15 and of regular tickets are 5.

Step-by-step explanation:

Given,

Total number of tickets = 20

Total amount = $225

Solution,

Let the number of early bird tickets be 'x'.

And also let the number of regular tickets be 'y'.

Now total number of tickets is the sum of number of early bird tickets and number of regular tickets.

So framing in equation form, we get;

Total number of tickets = number of early bird tickets + number of regular tickets

$x+y=20\ \ \ \ equation\ 1$

Again, Total amount is the sum of number of early bird tickets multiplied with price of each ticket and number of regular tickets multiplied with price of each ticket.

So framing in equation form, we get;

$10x+15y=225\ \ \ \ \ equation\ 2$

Hence the system of equation are $\left \{ x+y=20} \atop {10x+15y=225}} \right.$

Now we solve the equation by multiplying equation 1 by 10, and get;

$10(x+y)=20\times10\\\\10x+10y=200\ \ \ \ equation\ 3$

Now subtracting equation 3 from equation 2, we get;

$(10x+15y)-(10x+10y)=225-200\\\\10x+15y-10x-10y=25\\\\5y=25\\\\y=\frac{25}{5}=5$

On substituting the value of 'y' in equation 1, we get;

$x+y=20\\\\x+5=20\\\\x=20-5=15$

Hence The number of early bird tickets are 15 and of regular tickets are 5.

Which of the following explains how to use partial quotients to find 832 ÷ 26 ?

jeyben [28]

Answer:

C. Subtract 30 × 26 from 832 to get 52. Then subtract 2 x 26 from 52 to get 0.

Then add the partial quotients 30 + 2 to get 32. The quotient is 32.

Step-by-step explanation:

The attached shows the use of partial quotients to create the next dividend in the long division process. Each quotient digit is multiplied by the divisor and that product is subtracted from the dividend to create the next dividend. Then the process is repeated.

___

Here, the correct answer choice is the only one that has the correct quotient.
