Question

IF ANYONE CAN ANSWER THESE 2 QUESTIONS I WILL GIVE YOU BRAINLIEST AND LOVE YOU FOREVER. SERIOUSLY, ILL NEVER FORGET U <3

Answer 1

Answer:

3. 314 student and 226 adult

4. x = 6.5, y = -0.5

Step-by-step explanation:

3. First we will take our information and make a system of equations:

$2.4a+1.25s=934.9$

$a+s=540$

$a$ is the number of adult tickets sold and $s$ is the number of student tickets sold.

From the second equation we can rearange it to be:

$a=540-s$

Then we can plug in our new value of $a$ to our first equation

$2.4(540-s)+1.25s=934.9$

$1296-2.4s+1.25s=934.9$

$1.15s=361.1$

$s=314$

We can then find $a$ by plugging in s to our second equation

$a+314=540$

$a=226$

4. It is mostly solved already. We can take the value of y from the first equation and plug it into the second to get:

$3x -5(-5x+32)=22$

$3x+25x-160=22$

$28x=182$

$x=6.5$

Then plug our value of x into the first equation to get:

$3(6.5)-5y=22$

$19.5-5y=22$

$5y=-2.5$

$y=-0.5$
