What is (x+7)3y equal to
Answer:
(x + 7)3y = 3xy + 21y
Step-by-step explanation:
Expand the expression in the question by using the distributive property. This means you multiply the term (number) outside the bracket with each of the terms (numbers) inside the bracket.
(x + 7)3y Expand this
= (x)(3y) + (7)(3y) Multiply 3y with x and 7
= 3xy + 21y Simplified, final answer
Line XY bisects and is perpendicular to AB and CD. CD = 10 and XY = 24. What is the length of AP?
Answer:
AP = 13
Step-by-step explanation:
See the attached figure.
CD = 10 and XY = 24
Line XY bisects and is perpendicular to AB and CD
∴ XY bisects at Y
∴ CY = 0.5 CD = 0.5 * 10 = 5
And from the geometry of the shape
P is the midpoint of XY
∴ XP = YP = 0.5 XY = 0.5 * 24 = 12
XY is perpendicular to CD
∴ ΔPYC is a right triangle at Y
∴ PC (hypotenuse) = [tex]\sqrt{PY^2+YC^2} =\sqrt{12^2+5^2}=\sqrt{144+25} =\sqrt{169} =13[/tex]
From the figure AP = PC = 13

The green goober a wildly unpopular hero mixes 3 L of yellow paint was 5 L of blue plate to make a leader is a special green paint for his costume right in equation that relate to why the amount of yellow paint and leaders and be the amount of blue paint in liters needed to make the green goobers special green paint
Answer:
The equation can be y = 3b/5 or b = 5y/3
Correct statement and question:
The Green Goober, a wildly unpopular superhero, mixes 3 liters of yellow paint with 5 liters of blue paint to make 8 liters of special green paint for his costume.
Write an equation that relates the amounts (in liters) of yellow paint (y) and blue paint (b) needed to make the Green Goober's special green paint.
Source:
Previous question that can be found at brainly
Step-by-step explanation:
Let y to be the amount of liters of yellow paint needed to make the Green Goober's special green paint.
Let b to be the amount of liters of blue paint needed to make the Green Goober's special green paint.
We know that:
y:b = 3:5
Therefore,
5y = 3b, dividing by 5 at both sides we have:
y = 3b/5
And also dividing by 3 at both sides we have:
b = 5y/3
Both equations relate the amounts (in liters) of yellow paint and blue paint needed to make the Green Goober's special green paint.
The width of a photograph is 4 centimeters more than three tenths of the length. If the width is 13 centimeters, what’s the length?
Answer:
30 centimeters
Step-by-step explanation:
since the width is 4 centimeters more than 3/10 of the length, then 13 is 4 centimeters more than 3/10 of the length. 4 less than 13 is 9, so nine is 3/10 of the length. if 9 is 3/10, then 3 is 1/10 because 3/10 is three times 1/10. If 3 is 1/10, that means that 30 is the length because 1/10 multiplied by 10 is 10 tenths, or 1.

A saleswoman earns 20% commission on all the merchandise that she sells . Last month she sold $800 worth of merchandise . How much commission (in dollars) did she earn last month ?
Answer:
160
Step-by-step explanation:
20 percent of 800 is 160
The saleswoman earned a commission of $160 last month from selling $800 worth of merchandise, given that her commission rate was 20%.
Explanation:The subject of your question lies in the domain of Mathematics, specifically, a concept taught in Middle School known as percentages. In this case, we're tasked with finding out how much commission a saleswoman earned by selling $800 worth of merchandise, given that she earns a 20% commission on all items sold.
The process for calculating this is straightforward. You multiply the total amount of the sold merchandise by the percentage commission to find out the amount earned. In mathematical form:
Total commission earned = Total amount of items sold * Commission Rate
Substitute the given values into this equation:
Total commission earned = $800 * 20%
To convert the percentage to a decimal, you divide by 100, thus, 20% = 20/100 = 0.2
Hence, Total commission earned = $800 * 0.2 = $160
Therefore, the saleswoman earned a commission of $160 last month from selling the merchandise.

The left and right page numbers on an
open book add to 333. What are the
page numbers?
and
The student's question is a math problem involving consecutive numbers and a basic linear equation. The page numbers of an open book are consecutive, implying the left page is x and the right is x+1. Solving the equation x+(x+1)=333 results in the left page being 166 and the right page 167.
Explanation:The problem can be approached using the basic concept of consecutive integers in Mathematics. If the total sum of the two page numbers is 333, this means we are dealing with two consecutive numbers (since the left and right page numbers of an open book are always consecutive). Let's represent the left page number as x (unknown at this point). So, the right page number would be x+1 setting up our equation as x+(x+1)=333. Solving this equation will help us find the actual page numbers.
First combine like terms in your equation: 2x+1=333. Subtract 1 from both sides to isolate the term with x: 2x = 332 Divide both sides by 2 to solve for x: x = 166. This is our left page number. Substitute x in to x+1 to find the right page number: x+1 = 167. This is our right page number.
So, the left and right page numbers are 166 and 167 respectively.

The perimeter of a rectangle is 40 inches. If the length of the rectangle is 12 inches, which equation could be used to find the width, x?
A. x+2(12)=40
B. 12( x+2)=40
C. x+12 =40
D. 2(x+12) =40
Answer:
C. x + 12 = 40
Answer: D. 2(x+12) =40
Step-by-step explanation:
The Perimeter of a rectangle is calculated by the formula :
P = 2 ( length + width )
Let the width of the rectangle be x , then the perimeter becomes
40 = 2 ( 12 + x )
What is are if a rectangle of length of 5 and width of 3x-5y+6What is the area of a rectangle with a length of 5 and a width of 3x-5y+6
The area of rectangle is 15x - 25y + 30 sqaure units
Solution:
Given that, a rectangle with a length of 5 and a width of 3x - 5y + 6
To find: Area of rectangle
The area of rectangle is given by formula:
[tex]Area = length \times width[/tex]
From given,
Length = 5
Width = 3x - 5y + 6
Substituting the values in formula, we get,
[tex]Area = 5 \times (3x - 5y + 6)\\\\\text{Multiply 5 with each term inside the bracket }\\\\Area = 5(3x) -(5)(5y) +5(6)\\\\\text{Simplify the above expression }\\\\Area = 15x -25y + 30[/tex]
Thus area of rectangle is 15x - 25y + 30 sqaure units

If you know the diameter of a circle, how do you find its circumference?
Group of answer choices
Answer:
circumference of a circle [tex]C = 2\pi r=\pi (d)[/tex]
Step-by-step explanation:
Explanation:-
Circumference of a circle having radius is [tex]C = 2\pi r[/tex]
we know that the radius of circle is 'r'
The diameter of a circle is passing through the center of the given circle.
there fore the diameter of circle is equal to the two times of radius of given circle so d= 2 r
Circumference of a circle having diameter is
[tex]C= 2\pi r = 2r(\pi )[/tex]........(1)
we know that d = 2 r
now the equation (1) is [tex]C= d\pi[/tex]
Therefore The circumference of circle by using diameter is
[tex]C = \pi d[/tex]
Are 8÷2 and 2÷8 equivalent
Answer:
No, 8 / 2 and 2 / 8 are not equivalent.
Step-by-step explanation:
2 Numbers switched makes a different result.
For example, switching numbers in 82.
As we switch the 8 and the 2, we get 28.
28 is not equivalent to 82.
As we do 8 / 2, when we switch the numbers, we get 2 / 8.
2 / 8 is not equivalent to 8 / 2.
As we solve both equations, 8 / 2 = 4, 2 / 8 = 0.25.
0.25 is not equivalent to 4.
Therefore, 8 / 2 and 2 / 8 are not equivalent.

Answer:
Part a) [tex]y=-2x+4[/tex]
Part b) The coordinates of the point are [tex](\frac{4}{3},\frac{4}{3})[/tex]
Step-by-step explanation:
Part a) Find the equation representing the ladder
we have the ordered pairs
(0,4) and (2,0)
Find the slope
[tex]m=(0-4)/(2-0)=-2[/tex]
Find the equation of the line in slope intercept form
[tex]y=mx+b[/tex]
we have
[tex]m=-2\\b=4[/tex]
substitute
[tex]y=-2x+4[/tex]
Part b) A square box just fits under the ladder.Find the coordinates of the point where the box touches the ladder.
If the box is a square
the x-coordinate of the point where the box touches the ladder must be equal to the y-coordinate
x=y
[tex]y=-2x+4[/tex]
substitute
[tex]x=-2x+4\\3x=4\\x=\frac{4}{3}[/tex]
[tex]y=x=\frac{4}{3}[/tex]
therefore
The coordinates of the point are [tex](\frac{4}{3},\frac{4}{3})[/tex]
