Step-by-step explanation:
Answer:
8/12
Step-by-step explanation:
First
12 divided by 3 = 4
Second
since 12/3=4 you multiply 3x4 to get 12 so what you do to the denominator you do to the numerator so 2x4=8
Last
so that would give you
2/3 = 8/12
Answer:the width of the walkway is 5 feet
Step-by-step explanation:
Let x represent the width of the walkway.
The pool measures 10 ft by 20. If the walkway must have a uniform width around the entire pool, then the total length of the pool and the walkway would be 10 + x + x = 10 + 2x
The total width of the pool and the walkway would be 20 + x + x = 10 + 2x
The area covered by the pool and the cement walkway is 600 square feet. This means that
(10 + 2x)(20 + 2x) = 600
200 + 20x + 40x + 4x^2 = 600
4x^2 + 60x + 200 - 600 = 0
4x^2 + 60x - 400 = 0
Dividing through by 4, it becomes
x^2 + 15x - 100 = 0
x^2 + 20x - 5x - 100 = 0
x(x + 20) - 5(x + 20) = 0
(x - 5)(x + 20) = 0
x = 5 or x = - 20
The width cannot be negative. Therefore, the width of the walkway is 5 feet
-5x-4=46
-5x=46+4
-5x=50
÷both sides by -5x.
so your answer is going to be -10. and is so because u are diving with a negative number
The distance between A (4, 6) and B (9, 7) is √26 or 5.1.
<h3>How to find the distance between two points?</h3>
Let's consider we have two points (x₁, y₁) and (x₂, y₂) the distance between these two points is given by the formula;
Let's consider we have two points (x₁, y₁) and (x₂, y₂) the distance between these two points is given by the formula;
So the distance between A (4, 6) and B (9, 7) will be
d = √26 = 5.099
Rounded to nearest tenth ⇒ 5.1 units.
Hence "The distance between A (4, 6) and B (9, 7) is √26 or 5.1".
