If the other two friend also bought tickets for x dollars as the first three, than: 3x+3•8+2x=5x+24
If other two friends bought tickets for y dollars,different amount than x, than: 3x+3•8+2y=3x+24+2y=3x+2y+24
Answer:
upper and lower results have to be the same
so set them equal
5x = 2x + 1
subtract 2x on each side
3x = 1
devide each side by 3
x = 1/3
You are welcome
Answer:
k = - 3
Step-by-step explanation:
Given that x = 3 is a solution then it satisfies the equation, that is
2(3)² - 5(3) + k = 0
2(9) - 15 + k = 0
18 - 15 + k = 0
3 + k = 0 ( subtract 3 from both sides )
k = - 3
You need to find an area of one rectangular wooden plank 8*3,
and then top and the bottom area is 2*8*3
and total area is 12*2*8*3
