Answer:
x=(3a+5)/(2a-b)
Step-by-step explanation:
We spread the a to the 2x and -3 first,
2ax -3a= bx+5 5ax
By adding 3a, we pass the -3a over
2ax=bx+5+3aa bx+5+3aa
We'll pass the bx over the bx, then
2ax-bx=5+3aa-bx=5
Now we will party like this on the left side,
5+3a) x(2a-b)=5+3a)
Everything we have to do to find x is to separate both sides by (2a-b)
x=(3a+5)/=(3a+5)/ (2a-b)
Answer:
x = (5 + 3a)/(2a - b)
General Formulas and Concepts:
Pre-Algebra
Equality PropertiesStep-by-step explanation:
Step 1: Define equation
a(2x - 3) = bx + 5
Step 2: Solve for x
Distribute a: 2xa - 3a = bx + 5Add 3a on both sides: 2xa = bx + 5 + 3aSubtract bx on both sides: 2xa - bx = 5 + 3aFactor out x: x(2a - b) = 5 + 3aIsolate x: x = (5 + 3a)/(2a - b)What is the GCF for each set of numbers 15 and 35. show ur work

Garrett was given a sculpture that needs to have lights put around the outside only. How many inches of lights will be needed?
Answer:
204 in
Step-by-step explanation:
I can't really explain this other than that you have to add all the sides and the outside of this shape. For the hypotenuse you use the formula [tex]a^2+b^2=c^2[/tex]. Now just fill in what you know.
[tex]12^2+9^2=x^2\\144+81=x^2\\225=x^2\\x=15[/tex]
So we have:
length: 12in
base: 9in
hypotenuse: 15in
So now we do 12+15+9+15+12+15+9+15+12+15+9+15+12+15+9+15. Once we do all that we get 204 in.

Answer:
70
Step-by-step explanation:
Given is an isosceles triangle.
Angles opposite to equal sides are equal.
Therefore,
x° + x° + 40° = 180°
2x° = 180°- 40°
2x° = 140°
x°= 140°/2
x° = 70°
x = 70

urgent help ! similar figures use the similarity relationship to find the indicated value
Answer:
FE = 28 and YZ = 28
Step-by-step explanation:
In similar triangles the ratios of corresponding sides are equal.
(4)
[tex]\frac{BC}{FG}[/tex] = [tex]\frac{BD}{FE}[/tex] , substitute values
[tex]\frac{39}{4x+2}[/tex] = [tex]\frac{42}{5x-2}[/tex] ( cross- multiply )
39(5x - 2) = 42(4x + 2) ← distribute parenthesis on both sides
195x - 78 = 168x + 84 ( subtract 168x from both sides )
27x - 78 = 84 ( add 78 to both sides )
27x = 162 ( divide both sides by 27 )
x = 6
Thus
FE = 5x - 2 = 5(6) - 2 = 30 - 2 = 28
(5)
[tex]\frac{ST}{SZ}[/tex] = [tex]\frac{RT}{YZ}[/tex] , substitute values
[tex]\frac{40}{35}[/tex] = [tex]\frac{3x-7}{2x+2}[/tex] ( cross- multiply )
35(3x - 7) = 40(2x + 2) ← distribute parenthesis on both sides
105x - 245 = 80x + 80 ( subtract 80x from both sides )
25x - 245 = 80 ( add 245 to both sides )
25x = 325 ( divide both sides by 25 )
x = 13
Thus
YZ = 2x + 2 = 2(13) + 2 = 26 + 2 = 28
Following are the solution to the given graph points:
For question 4:
The ratios of equivalent edges of identical triangles are equal (4)
[tex]\to \frac{BC}{FG} = \frac{BD}{FE}[/tex]
Putting given value
[tex]\to \frac{39}{4x+2} = \frac{42}{5x-2}\\\\\to ({39}) ({5x-2}) = ({4x+2}) ({42})\\\\\to 195x -78= 168x+84\\\\\to 195x - 168x=84+78\\\\\to 27x=162\\\\\to x=\frac{162}{27}\\\\\to x=6[/tex]
Therefore,
[tex]\to FE = 5x - 2 = 5(6) - 2 = 30 - 2 = 28[/tex]
For question 6:
[tex]\to \frac{ST}{SZ} = \frac{RT}{YZ}[/tex]
Putting given value
[tex]\to \frac{40}{35} = \frac{3x-7}{2x+2}[/tex]
[tex]\to \frac{40}{35} = \frac{3x-7}{2x+2}\\\\\to 40(2x+2) = (35)(3x-7)\\\\\to 80x +80 = 105x-245 \\\\\to 80+245= 105x-80x\\\\\to 325= 25x\\\\ \to x= \frac{325}{25}\\\\\to x= 13[/tex]
Therefore,
[tex]\to YZ = 2x + 2 = 2(13) + 2 = 26 + 2 = 28[/tex]

Answer:
say no its not a right triangle
Step-by-step explanation:
bc u see the sides
and if u need the value of it its 432
Answer:
No
Step-by-step explanation:
You can check to see if the triangle is a right triangle or not by using the pythagorean theorem, which is a^2+b^2=c^2.
C is always the hypotenuse, which is the longest side of the triangle. So plug in 6 and 8 for a and b and 9 for c. Square them, and if the sum of a and b equals what c is, then it is a right triangle. Otherwise, it is not.
So let's check this triangle.
6^2+8^2= ?
36 + 64 = 100
9^2 is 81.
36 + 64 does not equal 81, so this is not a right triangle.
Emily bought 24 cans of soup for $54. Who paid the same price per can as Emily?
A) Candace bought 12 cans of soup for $26.
B) Ben bought 8 cans of soup for $18.
C) Raul bought 3 cars of soup for $6.
D) Devon bought 6 cans of soup for $14
Answer:
B
Step-by-step explanation:
as 18 divided by 8 is 2.25
and 54 divided by 24 is 2.25
The required only Ben paid the same price per can as Emily, which is $2.25. Option B is correct.
What is arithmetic?In mathematics, it deals with numbers of operations according to the statements. There are four major arithmetic operators, addition, subtraction, multiplication, and division,
To find out who paid the same price per can as Emily, we need to find the price per can for each option and compare it to Emily's price per can.
Emily's price per can:
$54 ÷ 24 = $2.25
Option A:
Candace bought 12 cans of soup for $26.
Price per can:
$26 ÷ 12 = $2.17
Similarly,
Option B:
Price per can = $2.25
Option C:
Price per can = $2.00
Option D:
Price per can = $2.33
We can see that only Ben paid the same price per can as Emily, which is $2.25.

A line passes through the point (-9,-8)
and is parallel to the graph y = - 4x + 4.
Write the equation that would represent
this line.
Answer:
y = -4x - 44
Step-by-step explanation:
Slope-intercept form: y = mx + b
Given equation: y = -4x + 4
Given point: (-9, -8)
To write the equation in slope-intercept form, we need to know the slope(m) and the y-intercept(b).
When two lines are parallel, their slopes are the same. Since the slope of the given line is -4, then the slope of the line parallel to it is also -4.
Now that we know the slope of the line, input the values of the slope and the given point into the equation format and solve for b:
y = mx + b
-8 = -4(-9) + b
-8 = 36 + b
Subtract 36 from both sides of the equation to isolate b:
-8 - 36 = 36 - 36 + b
-44 = b
The y-intercept is -44.
Now that we know the slope and the y-intercept, we can write the equation:
y = -4x - 44
