30/100=3/10
3 divided by 21 = 7
7*10 = 70!
The anwser is $70 I hoped that helped :3
Actually, this is worth 13 points. not 25. thanks!
Answer:
y = - x + 1
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = (- 1, 2) and (x₂, y₂ ) = (4, - 3)
m = 
= 
= -1, hence
y = - x + c ← is the partial equation
To find c substitute either of the 2 points into the partial equation
Using (- 1, 2), then
2 = 1 + c ⇒ c = 2 - 1 = 1
y = - x + 1 ← equation in slope- intercept form
Answer: 8 gallons of water.
Step-by-step explanation:
3 x 4 x 5 = 60.
60 divided by the number of gallons per cubic foot 7.5 = 8 gallons. :)
Answer: x=26
Step-by-step explanation:
Simplifying
2x + 3x + 50 = 180
Reorder the terms:
50 + 2x + 3x = 180
Combine like terms: 2x + 3x = 5x
50 + 5x = 180
Solving
50 + 5x = 180
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-50' to each side of the equation.
50 + -50 + 5x = 180 + -50
Combine like terms: 50 + -50 = 0
0 + 5x = 180 + -50
5x = 180 + -50
Combine like terms: 180 + -50 = 130
5x = 130
Divide each side by '5'.
x = 26
Simplifying
x = 26
