Answer:
x= 25
/2 and/or 12.5
Step-by-step explanation:
Let's solve your equation step-by-step.
300x+6250=10000
Step 1: Subtract 6250 from both sides.
300x+6250−6250=10000−6250
300x=3750
Step 2: Divide both sides by 300.
300x
/300
=
3750
/300
x=
25
/2
The point 0 represents the surface of the water. The height of the slide is 7 feet above the surface of the water. The bottom of the pole can be represented by -2 on the number line.
<h3>What is an
equation?</h3>
An equation is an expression that shows the relationship between two or more numbers and variables.
Given that −8 represents the depth of water in the swimming pool. Hence:

Answer:
Step-by-step explanation:
In order to find the value of n that satisfies this equation, we can perform a series of algebraic steps on it to solve for n.
- <em>Distribute in the 8 on the left side:</em>
- <em />
<em> </em> - <em>Add 4n to both sides</em>
- <em>Add 16 to both sides</em>
- <em>Divide both sides by 20</em>
Therefore, n=1 is the value of n that satisfies this equation.

Answer:
The dimensions are 7.4m by 15.1 m (to the nearest tenth).
Step-by-step explanation:
Area = length * width
If the width = x then the length = 3x - 7 so
Area x(3x - 7) = 111
3x^2 - 7x - 111 = 0
Using the quadratic formula:
x = [ -(-7) +/- √((-7)^2 - 4*3*-111)] / (2*3)
x = 7.36, -5.03.
The width must be positive s it is 7.36 m.
The length = 3(7.36) - 7
= 15.08 m.
