Answer:
Only one solution
Step-by-step explanation:
p=12
Solution below:
subtract p on both sides
9=p-3
add 3 on both sides
p=12

Perform the operation.
(x^2 + 8x + 8) + (-10x2 + 5x)
Answer:
-9x^2+13x+8
Step-by-step explanation:
Combine like terms-
(x^2 + 8x + 8) + (-10x^2 + 5x)
8x+5x = 13x
(x^2 + 8x + 8) + (-10x^2 + 5x)
-10x^2+x^2 = -9x^2
(x^2 + 8x + 8) + (-10x2 + 5x)
and 8 is just left over, so we put that all together and get...
-9x^2+13x+8
Good luck, have a great day!
EQ: How do you use elimination to solve a system of
equations?
Answer:
Step-by-step explanation:
when you use elimination you want to set two of the terms, in the different equations, equal to each other and then subtract the entire equation from the other, so that the two terms cancel out. Then you have an equation with one less variable in it. :)

A paved walkway around a garden has an outer diameter of 80 ft and an inner diameter of 40 ft. A diagram is shown below.
What is the approximate area of the paved walkway?
Given:
Outer diameter = D = 80 ftInner diameter = d = 40 ftSo,
Outer radius = R = D/2
=> R = (80 ft)/2
=> R = 40 ft
Inner radius = r = d/2
=> r = (40 ft)/2
=> r = 20 ft
Area of paved pathway = πR² - πr²
= π(R² - r²)
= π(R + r)(R - r)
= π(40 + 20)(40 - 20) ft²
= π(60)(20) ft²
= 3.14 * 1200 ft²
= 3768 ft²
can someone help?????
Answer:
what's the question?
Step-by-step explanation:
what the question
Answer:
The angle is 136 degrees because the 44 degree angle adds up to 180 since it is suplementary. so that means when u minus or take away 44 degrees from 180 it gives u 136.

How many 12 Feet 2 x 4 would be needed for Bottom Plates and Double Top Plates on a Building 25' x 50' ?
Your question has confusing details. So, I will rephrase as:
How many 2' x 4' would be needed for Bottom Plates and Double Top Plates on a Building 25' x 50' ?
Answer:
12.5 plates
Step-by-step explanation:
Given
Building dimension:
[tex]Length = 25ft[/tex]
[tex]Width = 50ft[/tex]
Plates
[tex]Length = 2ft[/tex]
[tex]Width= 4ft[/tex]
To do this, we have to divide the dimension of the building by the dimension of the plates
So, we have:
[tex]n = \frac{Length\ of\ Building}{Length\ of\ Plates}[/tex]
and
[tex]n = \frac{Width\ of\ Building}{Width\ of\ Plates}[/tex]
For the length, we have:
[tex]n = \frac{25}{2}[/tex]
[tex]n = 12.5[/tex]
For the width, we have:
[tex]n = \frac{50}{4}[/tex]
[tex]n = 12.5[/tex]
So, 12.5 of the plates are needed

Find the value of x and justify your answer
Answer:
a.
2x+4x+3x=180 sum of interior angle of the triangle is 180
9x=180
x=180/9=20
b.
x-20+x+10+x-20=180sum of interior angle of the triangle is 180
3x-30=180
3x=180+30
x=210/3=70
c.x+10+x+20+x=180 linear pair
3x+30=180
3x=180-30
x=150/3=50
Answer:
A: x=20
Step-by-step explanation:
angles in a triangle always equal 180° so knowing this 2x+3x+4x=180
9x=180
9x÷9=x
180÷9=20
20=c/5

Which set of ordered pairs represents y as a function of x?
Answer:
D is the correct answer
Explanation:
the following function satisfies each output to its input for the set D
f(x)=x/2
let's check each pair:
0/2=0
-1/2=-0.5
-2/2=-1
-3/2=-1.5
-4/2=-2
the reason why A, B, and C can't be pairs of inputs and outputs x and y it's because a variable x can't have more than one y (that's a behaviour of an equation not a function!)
- in A x=-1 | y=2, -2 and this wrong
- in B x=3 | y=9, 16 and this wrong
- in C x=0 | y=0, 1 and this wrong
I hope this was helpful
HELP ASAP. please show work. the plane of a room in the picture. the scale is 2 inches: 6 feet. what is the actual length, width , and area?
Answer:
Actual Length: 27 feet - Actual Width: 15 feet - Actual Area: 405 feet
Step-by-step explanation:
First, to find the length, you have to divide 9 by 2 to get 4.5 and then multiply it by 6 to get the actual amount of feet. Then you divide 5 by 2 and multiply the quotient by 6 to get the actual width. Then, you take the actual length (27 feet) and multiply it by the actual width (15 feet) and you get an area of 405 feet

Step-by-step explanation:
1. vertical angles are equal
(2x+17)=(4x+2)
15= 2x
x= 7.5
2. adjacent angles equal 180
(2m+8)+(3m-4)= 180
5m+4= 180
5m= 176
m= 35.2
3. (30s+5)=(20s+20)
10s= 15
s=1.5

Answer:
They only intersect once. (Correct letter is B)
Step-by-step explanation:
Slope Intercept Form:
2x - 4y = 3
-2x -2x
________
-4y = -2x + 3
Switch the signs of all of the numerals since you cannot have a negative 'y' value.
4y = 2x - 3
---- ---------
4 4
y= 1/2x - 3/4
-----------------------------------------------------------------------------------------------------------------
7y - 5x = 8
+5x +5x
----------------
7y = 5x + 8
---- ---------
7 7
y= 5/7x + 1 1/7
-----------------------------------------------------------------------------------------------------------------
After graphing the lines, you then can see that the lines only ever intersect once.

Use what you know about the angle sum theorem for triangles and your algebra skills to solve for x and find the measure of all three angles:
Answer:
2x° = 45°, 3x° = 67.5°
Step-by-step explanation:
Sum of angles in a triangle = 180°
2x+3x+3x=180°
8x=180°
x=22.5°
2x=22.5°x2=45°
3x=22.5°x3=67.5°
What’s the slope m and y-intercept b of both these images?
Answer:
Slope = 1
y-intercept = 3
Step-by-step explanation:
Since, slope of a line passing through two points [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] is given by,
Slope = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]
Therefore, slope of the line passing through two points (0, 3) and (-3, 0) will be,
Slope = [tex]\frac{3-0}{0-(-3)}[/tex]
Slope = 1
y-intercept of the line = distance between the origin and point of intersection of the line with y-axis
y-intercept = 3
