10) Solve the problem below using any method. Define your variables and write out the two

irga5000 [103]

Answer:

Variables: r, s

Number of Regular Tickets: 215

Equations: 8r + 6s = 3580; r + s = 525

Number of Senior Tickets: 310

Step-by-step explanation:

10) Solve the problem below using any method. Define your variables and write out the two equations. Then solve the problem.

A movie theater sells regular tickets for $8.00 and senior tickets for $6.00. One evening the theater

sold 525 tickets and took in $3580 in revenue. How many of each type of ticket were sold?

let r = number of regular tickets

let s = number of senior tickets

Equations:

The first equation deals with money.

8r + 6s = 3580

The second equation deals with numbers of tickets.

r + s = 525

Use the substitution method.

Solve the second equation for r.

r + s = 525

r = 525 - s

Substitute 525 - s for r in the first equation.

8r + 6s = 3580

8(525 - s) + 6s = 3580

4200 - 8s + 6s = 3580

4200 - 2s = 3580

-2s = -620

s = 310

Now substitute 310 for s in the equation r = 525 - s

r = 525 - 310

r = 215

Variables: r, s

Number of Regular Tickets: 215

Equations: 8r + 6s = 3580; r + s = 525

Number of Senior Tickets: 310

If the sum of four consecutive numbers is n, what is the first one?

serg [7]

$x - first\ number\\\\x,\ x+1,\ x+2,\ x+3-\text{four consecutive integers}\\\\\text{The equation:}\\\\x+(x+1)+(x+2)+(x+3)=n\\\\4x+6=n\ \ \ \ |-6\\\\4x=n-6\ \ \ \ \ |:4\\\\\boxed{x=\dfrac{n-6}{4}}$

$m, m+1,\ m+2,\ m+3,\ m+4,\ m+5,\ m+6-\text{seven consecutive numbers}\\\\\text{The sum}\\\\m+(m+1)+(m+2)+(m+3)+(m+4)+(m+5)+(m+6)=7m+21$

There are two different clocks in Wendy's house, one is 20 minutes faster in a day, and the other is 30 minutes slower in a day.

Annette [7]

Answer:

The answer is below

Step-by-step explanation:

For the first clock that is 20 minutes faster in a day, that means it is $\frac{20\ min}{60\ min/hr}=\frac{1}{3}hr$ faster every day. For it to show the correct time, the clock should be 24 hours faster.

Since 1 day = 1/3 hr faster

x days = 24 hr faster

Let x number of days be required to be 24 hr faster. To find x we use the formula:

$x=\frac{24 \ hr* 1\ day}{\frac{1}{3}hr } \\x=72\ days$

For the second clock that is 30 minutes slower in a day, that means it is $\frac{30\ min}{60\ min/hr}=\frac{1}{2}hr$ faster every day. For it to show the correct time, the clock should be 24 hours slower.

Since 1 day = 1/2 hr slower

y days = 24 hr faster

Let x number of days be required to be 24 hr slower. To find x we use the formula:

$y=\frac{24 \ hr* 1\ day}{\frac{1}{2}hr } \\y=48\ days$
