The quotient of a number and 6 minus is equal to the quotient of the number and 8. What is the number?
Answer:
that is one confusing word problem i don't understand it
Step-by-step explanation:
sorry i could't help
The number must be x = -2.
Here,
Let's represent the unknown number as "x."
According to the given information:
The quotient of a number and 6 minus is equal to the quotient of the number and 8.
This can be expressed as:
x / (6 - x) = x / 8
To solve for x, we can cross-multiply:
8 * x = x * (6 - x)
8x = 6x - x²
Now, let's move all terms to one side of the equation:
x² - 6x + 8x = 0
x² + 2x = 0
Factor out the common term "x":
x(x + 2) = 0
Now, we have two possible solutions:
x = 0
x + 2 = 0 => x = -2
Since we are looking for a real number solution,
the number must be x = -2.

Question?
Andre and Elena knew that after 28 days they would have 2²⁸ coins, but they wanted to find out how many coins that actually is. Andre wrote: 2 28 = 56. Elena said, “No, exponents mean repeated multiplication. It should be 28 28, which works out to be 784.”
Do you agree with either of them? Explain your reasoning.
Answer:
no, exponents are how many times the base is used, it would be 2x2x2... so on until there are 28 2s
Step-by-step explanation:
Both of them are incorrect.
What are Exponents and powers?The number of times a number is multiplied by itself is defined by the exponent. A mathematical term called the power illustrates the repeated multiplication of the same integer or factor.
Given:
[tex]2^{28}[/tex]
As, Andre wrote: 2 28 = 56.
Andre just normally multiplied the 2 and 28 to get 56.
Now, Elena said, “No, exponents mean repeated multiplication. It should be 28 28, which works out to be 784.”
According to Elena 2 to power 28 represents square of 28.
So, both are incorrect because [tex]2^{28}[/tex] means 2 is multiplied to itself 28 times which gives 268,435,456.

An equilateral triangle has three equal sides.
Write a relation for the perimeter of an equilateral triangle with side length k.
What is the perimeter of an equilateral triangle with side length 15 cm?
Answer:
Step 1. Perimeter P means adding up all three sides of a triangle.
Step 2. Then P=s+s+s=3s where s is the length of the side of the equilateral triangle.
Step 3. ANSWER: Perimeter P=3s.
I hope the above steps and explanation were helpful.
Step-by-step explanation:
HOPE THIS HELPS
Answer:
p = 3k
45cm
Step-by-step explanation:
Since all sides of an equilateral triangle are equal, to find perimeter, you multiply the number of sides by the length of one side.
So the equation would be p = 3k (k represents the side length and 3 is the number of sides)
If a equilateral triangle has a side length of 15, you just multiply 15 by the number of sides.
3 (15cm) = 45cm
if the surface area of a cube is 294, whats the length of the cube?
Answer:
7
Step-by-step explanation:
Total number of surfaces of cube are 6.
Each surface is square.
And area of square is (side)^2
That means, total surface area will be 6 * (side)^2
From question,
294 = 6 * (side)^2 ( Surface area given)
=> 294 ÷ 6 = ( side) ^2
=> 49 = side^2
=> √49 = side
=> 7 = side
So, length of edge of cube is 7

Step-by-step explanation:
Determine the intercepts of the line.
Answer:
x-intercept: (3, 0)
y-intercept: (0, -10)
Step-by-step explanation:
X-intercept:
We can see that the line crosses the x-axis at the 3. Let's imagine that this automatically makes a point. If the point is directly on the line, that means that the opposite coordinate (in this case, the y-coordinate) will be 0. This is because the point is directly at the 0 on the y-axis; it doesn't go up nor down.
Y-intercept:
The same goes for the opposite coordinate: if we picture a point at where the line intercepts the y-axis, there will be a point at -10 on the y-axis. Since the point is directly at 0 on the x-axis (meaning that it doesn't go left nor right) we know that the x-coordinate will be 0.
