CORRECT ANSWER GETS BRAINLIESTTTT!!!!!

Senior tickets (x)

Child tickets (y)

First day:  3x + 5y = 70

second day: 12x + 12y = 216

Solve the system of equations (use elimination)

Multiply first equation by -4   -4(3x + 5y = 70),  which makes it

-12x - 20y = -280

(+)12x + 12y = 216    add to second equation

-8y = -64

divide by -8.    y = 8

Plugin the y value to either equation ( I will choose first equation)

3x + 5(8) =70

3x+ 40 = 70

3x = 30

x = 10

Senior tickets are $10, child tickets are $8

Why math even exist people could just like wing it for everything
s2008m [1.1K]

Answer:

- 7 / 4

Step-by-step explanation:

( x1, y1 ) = ( 1, 10 )

Here,

x1 = 1

y1 = 10

( x2, y2 ) = ( 5, 3 )

Here,

x2 = 5

y2 = 3

Formula : -

Slope = ( y2 - y1 ) / ( x2 - x1 )

Slope = ( 3 - 10 ) / ( 5 - 1 )

Slope = - 7 / 4

Proper fraction = - 7 / 4

mark has 160 yards of fencing to enclose a rectangular garden whose length is to be four times its width what will be the dimens
vredina [299]

perimeter = 2W+2L

Length = 4W

160 = 2W +2(4W)

160 = 10W

w = 160/10 = 16 yards

length = 16*4 = 64 yards


Check:

64*2 = 128, 16*2 = 32

128+32 = 160

Length = 64 yards, Width = 16 yards
