Answer:
x=-4
Step-by-step explanation:
Multiply both sides by 50 and you get
3-x =7,
so x= -4
How many solutions exist for the given equation?
3(x – 2) = 22 – x
3(x - 2) = 22 - x
3x - 6 = 22 - x
3x + x = 22 + 6
4x = 28 / : 4
x = 7

a rectangular lawn has an area of a^3 - 125. use the difference of cubes to find out the dimensions of the rectangle.
The area of a rectangle is the product of its dimensions
The dimensions of the rectangle are: [tex]\mathbf{Length = a -5}[/tex] and [tex]\mathbf{Width = a^2 + 5a + 25}[/tex]
The area is given as:
[tex]\mathbf{Area = a^3 - 125}[/tex]
Express 125 as 5^3
[tex]\mathbf{Area = a^3 - 5^3}[/tex]
Apply difference of cubes
[tex]\mathbf{Area = (a - 5)(a^2 + 5a + 5^2)}[/tex]
[tex]\mathbf{Area = (a - 5)(a^2 + 5a + 25)}[/tex]
The area of a rectangle is:
[tex]\mathbf{Area = Length \times Width}[/tex]
So, by comparison:
[tex]\mathbf{Length = a -5}[/tex]
[tex]\mathbf{Width = a^2 + 5a + 25}[/tex]

Part A: Rhett made $250 washing cars with his mobile car wash company. He charges $70 per car and earned $50 in tips. Write an equation to represent this situation. (4 points)
Part B: Scarlett made a profit of $250.00 with her mobile car wash company. She charged $75.00 per car wash and received $35.00 in tips, but also had to pay $5.00 in cleaning supplies per car wash. Write an equation to represent this situation. (4 points)
Part C: Explain how the equations from Part A and Part B differ. (2 points)
Answer:
Part A 70x+50=250
Part B(75x + 35) = 250 - 5x
Step-by-step explanation:
Here to form an equation you must add all the money that she earned and subtract the money that she had to spend We dont know how many car washes she did, so we must represent it with a variable, or x.
Answer:
Step-by-step explanation:
Part A: Rhett washed 3 cars and earned $50 in tips. y=70x+50
Part B: $75 - $5 = $70 (this is the amount charged minus the amount needed to get the job done per car wash)
the +35 is the tips extra/ constant that will be added after the jobs are done.
x is the number of car washes done
y would be the profit received.
so y = 70x + 35 (profit = value of car wash * number of cars washed + tips)

Bella is planning a proof for the Isosceles Triangle Theorem using the following information and diagram. Given: APQR is an isosceles triangle with base PR Prove: ZP ZR First, she draws the angle bisector of ZQ and labels it QB. She plans to show that ZP and ZR are corresponding parts of congruent triangles. Which congruence criterion can be used in her proof to show that APQB ARQB? A. ASA B. SAS C. SSS
Similar triangles may or may not be congruent.
The congruent criterion to use in her proof is (b) SAS theorem
From the question, we understand that she draws an angle bisector from [tex]\mathbf{\angle Q}[/tex] to side PR
This means that, either sides of angle Q are congruent. (this is represented by A i.e. angle)
When [tex]\mathbf{\angle Q}[/tex] is bisected, sides PB and RB become congruent
i.e. [tex]\mathbf{PB \cong RB}[/tex] ... (this is represented by S i.e. side)
Lastly, both triangles share a common side at QB .. (this is also represented by S i.e. side)
So, we have: SAS
Hence, the congruent criterion to use in her proof is (b) SAS theorem

the sum of the measures of the angles of all triangles is 180 degrees.if one angle of the triangle measures 45 degrees,and other two angles are equal.what is the measure of the other two angles?
Answer:
67.5 degrees.
Step-by-step explanation:
Let the measure of two equal angles of the triangles is x.
Thus, the angles of the triangles are x, x and 45 degrees.
Answer:
67.5°
Step-by-step explanation:
Given:
All triangles is 180°
One Triangle measure 45°
2 Other Angles are equal
To Find:
Two Other Angles
Solution:
180°- 45° = 135°
135° ÷ 2 = 67.5°
Therefore the other two angles are 67.5°
The sum of three numbers is 137. The second number is 4 more than two times the first number. The third number is less than three times the first number. Find the three numbers.
Answer:
23, 50, 64
Step-by-step explanation:
137 = 23 + 50 + 64
Let the first number be x
Second number: 2x+4
Third number: 3x-5
Write the equation:
x + (2x + 4) + (3x-5) = 137
Solve for "x"
6x - 1 = 137
6x = 138
x = 23
Plug x (23) into the equation:
x + (2x + 4) + (3x-5) = 137
23 + 2(23) + 4 + 3(23) - 5 = 137
(23 + 46 + 4 + 69) - 5 = 137
142 - 5 = 137

Step-by-step explanation:
Select all that apply. To create perpendicular lines, I can transform a line by:
1. Rotating the line 270° around any point.
2. Translating the line horizontally.
3. Rotating the line 45° around any point, then rotating it another 45° around any point.
4. Translating the line vertically.
5. Reflecting the line over itself.
6. Rotating the line 45° around any point.
7. Reflecting the line over any point on the line.
8. Rotating the line 90° around any point.
Answer:
8. Rotating the line 90° around any point.
Step-by-step explanation:
Perpendicular lines intersect each other at a right angle. Therefore, the transformation should create an image that intersects the preimage at an angle of 90∘. Since a rotation changes the angle between the preimage and the image, it can create perpendicular lines.
