Factor the expression using the GCF: 15x - 25
To factor the expression 15x - 25 using the greatest common factor (GCF), divide each term by the GCF. The factored form is 5(3x - 5).
Explanation:To factor the expression 15x - 25 using the greatest common factor (GCF), we need to find the largest number that divides both terms evenly. In this case, the GCF is 5. We can then divide each term by 5 to factor out the GCF:
15x ÷ 5 = 3x
-25 ÷ 5 = -5
Therefore, the factored form of the expression 15x - 25 is 5(3x - 5).
The expression 15x - 25 is factored by finding the Greatest Common Factor, which is 5, and then dividing each term by 5 to get the factored expression 5(3x - 5).
To factor the expression using the Greatest Common Factor (GCF), we need to identify the highest number that divides both coefficients in the expression 15x - 25. In this case, both 15 and 25 are divisible by 5, so 5 is the GCF of the expression. Applying the distributive property, we factor out the GCF:
Determine the GCF: 5.Divide each term by the GCF: 15x/5 = 3x and 25/5 = 5.Write the factored expression: 5(3x - 5).Now, the expression 15x - 25 is fully factored as 5(3x - 5).
Simplify:
(x-y)/(x+y) - (x+y)/(x-y) =
Final answer:
The simplified form of the expression (x-y)/(x+y) - (x+y)/(x-y) is -4xy / (x²-y²).
Explanation:
To simplify the expression (x-y)/(x+y) - (x+y)/(x-y), we need to find a common denominator and then combine the terms.
The common denominator for the fractions is (x+y)(x-y), which is the product of both denominators and simplifies to x²-y² due to the difference of squares.
Let's go ahead and combine the fractions over this common denominator:
((x-y)² - (x+y)²) / (x²-y²)
Expanding the numerators gives:
(x² - 2xy + y²) - (x² + 2xy - y²) / (x²-y²)
Now, simplify by combining like terms:
(x² - x² - 2xy - 2xy + y² - y²) / (x²-y²)
Cancelling out the x² and y² terms, we are left with:
-4xy / (x²-y²)
Thus, the simplified form of the given expression is:
-4xy / (x²-y²)

Solve by substitution:
2x+6y=16
3x-5y=-18
Answer:
Step-by-step explanation:
y= 16
x=15
Using the substitution method,
The value of x is -1 and y is 3.
What is an equation?An equation is a mathematical statement that is made up of two expressions connected by an equal sign.
Example:
2x + 3 = 8 is an equation.
We have,
2x + 6y = 16 _____(1)
3x - 5y = -18 ______(2)
From (1) we get,
2x = 16 - 6y
x = (16 - 6y)/2
Substituting in (2).
3x - 5y = -18
3 x (16 - 6y)/2 ) - 5y = -18
3 x (8 - 3y) - 5y = -18
24 - 9y - 5y = -18
24 + 18 = 9y + 5y
42 = 14y
y = 42/14
y = 3
And,
x = (16 - 6y)/2
x = (16 - 6 x 3) / 2
x = (16 - 18) / 2
x = -2/2
x = -1
Thus,
x = -1 and y = 3.

Mother ordered 4 boxes of cupcakes for John's birthday party. As they had more guests than expected, mother ordered 2 more similar boxes of cupcakes. How many cupcakes did each box contain, if there were in total 108 cupcakes for John's birthday party?
Answer:
each box contained 18
Step-by-step explanation:
because 108 divided by the total number of boxes = 18
Final answer:
To determine how many cupcakes were in each of the 6 boxes for John's party with a total of 108 cupcakes, simply divide 108 by 6, resulting in 18 cupcakes per box.
Explanation:
The question asks us to determine how many cupcakes each box contained if there were a total of 108 cupcakes for John's birthday party, and 6 similar boxes were ordered in total. To find the answer, we divide the total number of cupcakes by the total number of boxes.
First, we know that the mother ordered 4 boxes initially and then ordered 2 more boxes, which gives us a total of 4 + 2 = 6 boxes. Then, we are given the total number of cupcakes, which is 108. To find out how many cupcakes each box contained, we divide the total number of cupcakes by the number of boxes:
108 cupcakes ÷ 6 boxes = 18 cupcakes per box
Therefore, each box contained 18 cupcakes.

A cone has a volume of 33 cubic inches. If
a cylinder has the same height and the same
radius as the cone, what is the volume of the
cylinder?
Answer:
The volume of the cylinder is
[tex]V=99\ in^3[/tex]
Step-by-step explanation:
we know that
The volume of the cone is equal to
[tex]V=\frac{1}{3}\pi r^{2}h[/tex]
[tex]V=33\ in^3[/tex]
so
[tex]33=\frac{1}{3}\pi r^{2}h[/tex]
Multiply by 3 both sides
[tex]99=\pi r^{2}h[/tex] ----> equation A
Remember that
The volume of a cylinder is equal to
[tex]V=\pi r^{2}h[/tex]
The cylinder has the same height and the same radius as the cone
so
Equate the volume of cylinder to equation A
[tex]V=99\ in^3[/tex]
The volume of the cylinder is 99 cubic inches and this can be determined by using the formula of the volume of the cylinder and the volume of the cone.
Given :
A cone has a volume of 33 cubic inches. A cylinder has the same height and the same radius as the cone.The formula of the volume of a cone is given by:
[tex]\rm V = \dfrac{1}{3}\pi r^2h[/tex]
[tex]\rm 3V = \pi r^2h[/tex] --- (1)
The formula of the volume of the cylinder is given by:
[tex]\rm V' = \pi (r')^2 h'[/tex] --- (2)
According to the given data, the cylinder has the same height and the same radius as the cone. That is:
h' = h
r' = r
So, from equations (1) and (2):
V' = 3V
According to the given data, V = 33 cubic inches.
V' = 3(33)
V' = 99 cubic inches
So, the volume of the cylinder is 99 cubic inches.

The graph of a linear function is shown.
A coordinate plane with a straight line. The line starts at (negative 5, negative 1) and continues up and to the right passing through (0, 0) and (5, 1).
Which word describes the slope of the line?
positive
negative
zero
undefined
See picture for answer and explanation.
We can completely define a line equation by only knowing two points on the line, so we will use that to find our line's slope.
The slope is positive. (We will see that the slope is equal to 1/5).
The first general rule is that, if the line, readen from lest to right increases, then the slope is positive. (Here by the description we know that it increases).
But let's find the slope to see this.
If we know that the line passes through two points (x₁, y₁) and (x₂, y₂) then we can write the slope as:
[tex]a = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
Here we can use two of the given points to find the slope, I will use the first two: (-5, -1) and (0, 0)
We will get:
[tex]a = \frac{0 - (-1)}{0 - (-5)} = \frac{1}{5}[/tex]
So the slope is 1/5, which is positive.
Then the correct option is the first one.

the sum of twice a number and 4 times another number is 4. the first number decreased by the second number is 5. Find the numbers
The two numbers being asked in the question are 4 and -1.
Explanation:This question can be solved using a system of linear equations. Let's call the first number x and the second number y.
From the first statement, we can create one equation: 2x + 4y = 4
From the second statement, we can create another equation: x - y = 5
To solve this system, we can use substitution or elimination method. If we multiply the second equation by 2, we get 2x - 2y = 10. Now, we can subtract the second equation from the first: (2x + 4y) - (2x - 2y) = 4 - 10, which simplifies to 6y = -6. Dividing both sides by 6, we get y = -1.
Substitute y = -1 into the equation x - y = 5, we get x - (-1) = 5. Therefore, x = 5 - 1 = 4.
So, the first number x is 4 and the second number y is -1.

y and z are whole numbers. y<80 and z less than or equal to 70 work out the largest possible value of y+z
Final answer:
The largest possible value for y + z, with y < 80 and z ≤ 70, is 149, achieved by taking the maximum whole numbers within those limits: y = 79 and z = 70.
Explanation:
To find the largest possible value of y + z given that y is a whole number less than 80 and z is a whole number less than or equal to 70, we must choose the largest whole numbers that fit these conditions. For y, the largest whole number less than 80 is 79, and for z, the largest whole number less than or equal to 70 is 70 itself. Therefore, the largest possible value for y + z is 79 + 70.
The calculation is straightforward:
79 (maximum y) + 70 (maximum z) = 149
This is the largest sum of y + z based on the given conditions.

(1) Direct expansion
(4x + 1)(4x + 1 )
4x X 4x + 4x X 1 + 1 X 4x + 1 X 1
= 16x² + 4x + 4x + 1

(4x + 1 )(4x + 1 ) = (4x + 1 )²
= (4x)² + 2( 4x X 1 ) + 1²
= 16x² + 2(4x) + 1
= 16x² + 8x + 1.
(4x + 1)(4x + 1)
4x · 4x = 16x²
4x · 1 = 4x

He uses all the cans.how much of each of this bigs will have and how much cans of fruitwill they have and how much cans of vegetables will they have
Answer:
William will make 12 bags of food and each of the bag will contains 2 cans of fruit and 5 cans of vegetables.
Step-by-step explanation:
Given:
Number of fruits cans = 24
Number of veggies cans = 60
William will have to distribute them in equal bags with equal cans of fruits and vegetables respectively.
For this:
We have to find the GCF (greatest common factor) of 24 and 60.
GCF by listing out the factors method.
Factors of 24 : [tex]1,2,3,4,6,8,12,24[/tex]
Factors of 60 : [tex]1,2,3,4,5,6,10,12,15,20,30,60[/tex]
So,
The greatest common factor of [tex]24[/tex] and [tex]60[/tex] is [tex]12[/tex].
The number of bags William will used for equal distribution = [tex]12[/tex]
Now,
We have to distribute the veggies and fruits in equal number of cans to these [tex]12[/tex]bags.
Number of fruits cans used in each bag = [tex]\frac{24}{12} = 2[/tex]
Number of vegetables can used in each bag = [tex]\frac{60}{12} =5[/tex]
We can say that:
William will make 12 bags of food and each of the bag will contains 2 cans of fruit and 5 cans of vegetables.
Final answer:
By computing the greatest common divisor (GCD) of 24 and 60, it is determined that William can create 12 equal bags with each bag having 2 cans of fruit and 5 cans of vegetables.
Explanation:
The student is asking how to divide 24 cans of fruit and 60 cans of vegetables into bags such that each bag contains the same number of cans without any leftovers. This requires finding the greatest common divisor (GCD) of 24 and 60, which is 12. Therefore, William can make 12 bags, with each bag containing 2 cans of fruit and 5 cans of vegetables.
