Let's try to make two equations.
X+Y=28
Since x is three time y, x=3y. Let's fill that in for x.
3y+Y=28
Let's solve first by combining like terms.
4y=28
28÷4=7=y
Y is 7, so that means x must be 21 since their sum is 28.
So, 21=x and 7=y.

At a raffle, 1500 tickets are sold for $2 each for four prizes of $500, $250, $150, and $75. You buy one ticket. What is the exp
Kisachek [45]
To find the expected value of your gain in each prize, subtract the price of the ticket from the prize:

If the prize is $500: $500 - $2 = $498
If the prize is $250:  $250 - $2 = 248
If the prize is $160: $160 - $2 = $73

But if you did not win any cash prize, you do not have any gain because
0 cash prize - $2 ticket = -$2 which is a loss

If x =2 y=3 z=4 solve the following<br><br> x² + y²
Tanya [424]

Answer:

13

Step-by-step explanation:

Given x = 2, y = 3 and z = 4. We'll evaluate the value of x² + y² with given condition.

First, remind that we are only given the expression of x-term and y-term only and therefore, z-term is not included - it's not to be considered.

Substitute x = 2 and y = 3 in the expression:

\displaystyle{2^2+3^2 = 4+9}\\\\\displaystyle{4+9 = 13}

Hence, the value of x² + y² when x = 2 and y = 3 is 13.

Please let me know if you have any questions!
