Tickets to a concert cost $2 for children, $3 for teenagers and $5 for adults. When 570 people attended the concert, the total t

-Dominant- [34]

Let

x--------> the number of children

y------> the number of teenagers

z------> the number of adults

we know that

$2x+3y+5z=1,950$ ------> equation A

$x+y+z=570$ -----> equation B

$y=\frac{3}{4}x$

$x=\frac{4}{3}y$ -------> equation C

Substitute equation C in equation A and equation B

$2[\frac{4}{3}y]+3y+5z=1,950$

$\frac{17}{3}y+5z=1,950$ --------> equation D

$[\frac{4}{3}y]+y+z=570$

$\frac{7}{3}y+z=570$ --------> equation E

Multiply equation E by $-5$

$-\frac{35}{3}y-5z=-2,850$ --------> equation F

Adds equation D and equation F

$\frac{17}{3}y+5z=1,950\\\\-\frac{35}{3}y-5z=-2,850\\\\---------\\\\-\frac{18}{3}y=-900\\\\y=3*900/18\\\\y=150\ teenagers$

therefore

<u>the answer is the option</u>

$150\ teenagers$

fabiana decides to save the money she is earning from her after school job for college. she makes an initial contribution of 300

Oxana [17]

Answer:

A. Total Money Contributed after n months = $\$ 3000 + \$ (500\times n)$

B. Total Money Contributed after 24 months = $\$ \ 15000$

Step-by-step explanation:

Given:

Initial contribution = $\$\ 3000$

each month contribution = $\$\ 500$

After 1 month contributed = $\$\ 3000 + \$\ 500 \times 1= \$ \ 3500$

Solving for Part A

let n be the number of months

∴ Total Contribution after n months = Initial contribution + (each month contribution $\times$ Number of months = $\$\ 3000 + \$\ 500 \times n$

Solving for Part A

Now n= 24 months

∴ Total Contribution after 24 months = $\$\ 3000 + \$\ 500 \times 24 = \$\ 3000 + \$\ 12000= \$\ 15000$

Need help factoring this binomial: x^4-1?

natima [27]

Use the difference of squares factorization - that for any numbers a and b, (a-b)(a+b)=a^2-b^2.

We have:

(x^2+1)(x^2-1)=x^4-1

In addition:

(x-1)(x+1)=x^2-1, so we have:

(x^2+1)(x+1)(x-1)

As our complete factorization.
