You would subtract the x and move it over to the other side so your equation would be
8y= -15 + x
you would then divide everything by 8 so you can have y on its own so it would be
y= -15/8 + x/8
so your final equation is
y=-15/8 +8x
for the second equation it’s the same thing, you subtract 7x
8y= -19 + 7x
divide by 8
y= -19/8 +7/8x
In this equation we start by filling in the N with "1" then"2" then "3" and so on
3n+4=
3(1)+4=7
3(2)+4=10
3(3)+4=13
3(4)+4=16
Solve using system of equations.
y=total money spent, x=amount of rides
y=12+3.5x
y=33
Solve! Set them equal to each other
12+3.5x=33
-12 -12
3.5x=21
x=6
After six rides the all day pass would be cheaper. ;)
Answer:
There are about 3.281 * 3.281 = 10.764 square feet in one square meter. Therefore, 22.5 square feet is 22.5 / 10.764 = 2.09 square meters.
