Answer:
x=3 y=-1
Step-by-step explanation:
To get the value of x you need to put in the second equation which is y=8-3x as the y value for the first equation which is 2x+3y=3 making it
2x+3(8-3x)=3
2x+24-9x =3
24-7x =3
-7x=-21
Multiplying both sides by -7
x= 3
After getting an x value you substitute it in the equation in order to find your y value which is
2x+3y=3
2(3)+3y=3
3y=-3
Multiplying both sides by 3
y= <u>-3</u>
3
y=-1
Let a and c be adults and children, respectively. Then:
a+c=500
5a+2c=1540
Solve for a and c

Answer: in the picture.... hope this helps! :)
Volume of the rectangular prism = l * w * h
Diagonal = √l² + w² + h²
= √ 16² + 12² + 8²
= √464
= 21.5
