21,000 rounded to the nearest thousand will be 20,000
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. ;)
<span>Simplifying
4x + 8y = 30.60
Solving
4x + 8y = 30.60
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-8y' to each side of the equation.
4x + 8y + -8y = 30.60 + -8y
Combine like terms: 8y + -8y = 0
4x + 0 = 30.60 + -8y
4x = 30.60 + -8y
Divide each side by '4'.
x = 7.65 + -2y
Simplifying
x = 7.65 + -2y</span>
Answer:
5x +2y
Step-by-step explanation:
3x + 4y + 2x - 2y -> remove parenthesis
5x +2y -> combine like terms ( 3x + 2x = 5x and 4y - 2y = 2y)

Answer:
a = 6.25 m/s²
T = 5⅓ seconds
Step-by-step explanation:
a = (v - u)/t
v = 120×1000/3600 = 100/3
a = 100/3t
v² = u² + 2as
(100/3)² = 2(100/3t)(88 8/9)
10000/9 = (200/3t)(800/9)
200/3t = 12.5
t = 5⅓ seconds
a = 6.25
