find the value of X and please show your work.
Answer:
x= -22
Step-by-step explanation:
3x=5x+44
subtract 2x from both sides and leave only x on one side 3x(-2x)=5x(-2x)+44
then you get
x=3x+44
then you subtract the 3x to both sides
x(-3x)=3x(-3x)+44
then you get
-2x=44
and divide 2 on each side so-
x= -22

x² = c/a . . . . . . divide by a
x = ±√(c/a) . . . . take the square root
La frase lingüística "cuatro veces un número dividido por la suma de dos
números", escrita como una frase algebraica es:Opción única.
(1 Punto)
4 + +
4 ÷ +

4 +
Answer:
Las opciones no se pueden ver, así que responderé de una forma general.
Primero rompamos la frase en partes más cortas
"cuatro veces un número..."
Esto se escribe como 4*N, donde N es el número.
"... la suma de dos
números"
Esto se escribe como K + M
donde K y M son dos números, entonces K + M es la suma de dos números.
Entonces:
"cuatro veces un número dividido por la suma de dos
números"
Se escribirá como:
(4*N)/(K + M )

Four less than two times a number is seven times the sum of that number and 8. Which equation
could be used to solve this problem?
1. 4- 2n + 7n = 8
2. 2n - 4 = 7n + 8
3. 2n - 4 = 7(n + 8)
4. 4 - 2n = 7(n + 8)
9514 1404 393
Answer:
3. 2n - 4 = 7(n + 8)
Step-by-step explanation:
Two times a number is 2n. Four less than 2n is (2n-4). The sum of a number and 8 is (n+8). Seven times that sum is 7(n+8). The statement says these values are equal:
2n -4 = 7(n +8)

Write an equation that represents a perpendicular line to y=-3x+5
Answer:
Example
Step-by-step explanation:
The slope-intercept form is y=mx+b y = m x + b , where m m is the slope and b b is the y-intercept. Using the slope-intercept form, the slope is 3 3 . The equation of a perpendicular line to y=3x−5 y = 3 x - 5 must have a slope that is the negative reciprocal of the original slope.

Eber can mow 4 lawns in one hour. The equation l = 4h can be used to determine the number of lawns, 1. Eber can
mow in h hours. Create a graph to represent the number of lawns Eber can mow in 0 to 5 hours. Click on the
coordinate plane to place the points in the correct locations.
Answer:
See attachment for plot
Step-by-step explanation:
Given
[tex]l = 4h[/tex]
Required
Represent the scenario on a graph
When h = 0
[tex]l = 4h= 4 * 0 = 0[/tex]
When h = 1
[tex]l = 4 * 1 = 4[/tex]
When h = 2
[tex]l = 4 * 2 = 8[/tex]
When h = 3
[tex]l = 4 * 3 = 12[/tex]
When h = 4
[tex]l = 4 * 4 = 16[/tex]
When h = 5
[tex]l = 4 * 5 = 20[/tex]
So, we have:
[tex](h,l) = (0,0)[/tex]
[tex](h,l) = (1,4)[/tex]
[tex](h,l) = (2,8)[/tex]
[tex](h,l) = (3,12)[/tex]
[tex](h,l)= (4,16)[/tex]
[tex](h,l)= (5,20)[/tex]

Answer:
Hello! answer: r = 7
Step-by-step explanation:
Hi im sorry I will try to explain this the simplest way possible! so all of this will add up to 180 we know 1 angle is 55 and the 1 that isnt labelled is 90 because its a complementary angle leta add those and subtract so we can figure out what our last angle will have to equal so... 55 + 90 = 145
180 - 145 = 35 so now we know the last angle will have to equal 35 r is just a place holder its just representing something multiplied by 6 subtracted by 7 will equal 35 so...
6 × 7 = 42 and 42 - 7 = 35 So 7 is r!! Hope that helps!
Find the value of x and 3x
Right angle =90°
The sum angle of triangle =180°
A turn =360°
(90-45)+(90-45)+a=180°
45+45+a=180°
90+a=180°
a=90°
a+3x=360°
90°+3x=360°
3x=270°
3x=270°
x=90°

Segment AB is tangent to O T at B. What is the radius of OT?
The circle T has a radius of 28 units. (Correct choice: C)
How to determine the radius of a circle
The geometrical system shown in the image is formed by a triangle and a circle, since the line segment AB is tangent to the circle, then it is perpendicular to the radius of the circle and the triangle is a right triangle. This figure is described by the Pythagorean theorem:
AT² = AB² + TB²
(AC + CT)² = AB² + TB²
(25 + r)² = 45² + r²
25² + 50 · r + r² = 45² + r²
50 · r = 45² - 25²
r = (45² - 25²) / 50
r = 28
The circle T has a radius of 28 units. (Correct choice: C)

A youth group sells cookles for $8 a boxIf they spent 1000 buying the cookies, which equation below shows the profit () made by the group after selling (b) boxes?
Answer:
D) P = 8b - 1000
Step-by-step explanation:
Think about it,
First off
If they spent 1000 from just buying the cookies. When you buy something you lose money. So that's -1000.
Secondly,
If they charged $8 per box that would cost an additional eight dollars each time a cutomer perchased a box. Another way to show addition is multiplication.
Ex if someone bought 7 box and 8 dollars each it could be shown as either:
1. 7 + 7 + 7 + 7 + 7 + 7 + 7 + 7
2. 8 + 8 + 8 + 8 + 8 + 8 + 8
3. 7 x 8 or 8 x7
So 8b - 1000 would make the most sense.
