Answer:
(18 + 36 + 27) = 9 x (2+4+3)
(88 + 66 + 22) = 22 x (4+3+1)
(36 + 96 + 12) = 12 x (3+8+1)
(126 + 28 + 14) = 14 x (9+2+1)
(54 + 81 + 27) = 27 x (2+3+1)
(16 + 28 + 48) = 4 x (4+7+12)
Step-by-step explanation:
The equations in the solution represent each expression as a multiple of a sum of whole numbers with no common factor.
What is the algebraic expression?Algebraic expressions are mathematical statements with a minimum of two terms containing variables or numbers.
As per the given question, the required solution would be as:
(18 + 36 + 27) = 9 × (2+4+3)
This equation represents each expression as a multiple of a sum of whole numbers with no common factor.
Similarly further equations like as :
(88 + 66 + 22) = 22 × (4+3+1)
(36 + 96 + 12) = 12 × (3+8+1)
(126 + 28 + 14) = 14 × (9+2+1)
(54 + 81 + 27) = 27 × (2+3+1)
(16 + 28 + 48) = 4 × (4+7+12)
Thus, the above equations represent each expression as a multiple of a sum of whole numbers with no common factor.

Answer:
No
Step-by-step explanation:
Solve for x: 3(x + 1) = −2(x − 1) − 4.
Answer:
x = -1
Step-by-step explanation:
3(x+1) = -2(x-1) - 4 (Use the distributive property on both sides)
3x + 3 = -2x + 2 - 4 (collect like terms on the right side)
3x + 3 = -2x - 2 ( add 2x on both sides)
5x + 3 = -2 ( subtract 3 on both sides)
5x = - 5 (divide by 5 on both sides)
x = -1

In your own words, explain how to find the rate of change of the following graph at x=1. Then find the rate of change at x=1.
Answer:
Rate of change of the graph = 1
Step-by-step explanation:
Rate of change of the graph at any point is defined by the slope of the line at that point.
Since, slope of a line between two points [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] is given by,
m = [tex]\frac{y_2-y_1}{x_2-x_1}=\frac{\triangle y}{\triangle x}[/tex]
In other words, slope of a line between two points is given by the ratio of rise and run of the line between the given points.
Therefore, slope of the line passing through two points (0, 2) and (1, 3) will be,
m = [tex]\frac{3-2}{1-0}[/tex]
m = 1
Rate of change at x = 1 is 1.
Find ABC, Please help!
Answer:
50°
Step-by-step explanation:
Angle A = AngleB (Corresponding angles)
x=2x-50
x=50°
Hope it helps
Answer:
∠ ABC = 50°
Step-by-step explanation:
2x - 50 and x are corresponding angles and congruent, thus
2x - 50 = x ( subtract x from both sides )
x - 50 = 0 ( add 50 to both sides )
x = 50
Thus
∠ ABC = x = 50°

An airplane travels 4,425 kilometers west in 5 hours. What is its average velocity?
Answer:
Option C. 885 km/h West
Explanation:
Data obtained from the question. This include the following:
Displacement = 4425 Km due West
Time = 5 hours
Velocity =?
Velocity is defined as displacement per unit time. Mathematically, it is expressed as
Velocity = Displacement /Time
With the above formula, we can calculate the velocity of the plane as follow:
Velocity = Displacement /Time
Velocity = 4425/5
Velocity = 885 km/h West

Tina is building a birdhouse. The plans have a scale of
1 cm : 2.5 inches. A rectangular wall of her birdhouse has a drawing length of 2 cm and a width of 4 cm. What will the actual area of the wall be?
Answer: Actual area of wall = 50 sq. inches
Step-by-step explanation:
Given: Scale : 1 cm : 2.5 inches
A rectangular wall of her birdhouse has a drawing length of 2 cm and a width of 4 cm. What will the actual area of the wall be?
So, Actual length = 2 x 2.5 inches = 5 inches
Actual width = 4 x 2.5 inches = 10 inches
Actual area = Actual length x Actual width
= 5 x 10 = 50 sq. inches
Hence, Actual area of wall = 50 sq. inches

if abc is an isosceles triangle and m∠A=40º,what are possible measures for angles B and C
Answer:
They could both be 70
Step-by-step explanation:
The reason why is because if you subtract 40 from 180 you get 140 and that can be evenly split in 2 ways by 70.
An isosceles triangle is one with two equal-length sides. The possible measures for ∠B and ∠C are 70°.
What is an isosceles triangle?An isosceles triangle is one with two equal-length sides. It is sometimes stated as having exactly two equal-length sides, and sometimes as having at least two equal-length sides, with the latter form containing the equilateral triangle as a particular case.
Since in an isosceles triangle the measure of any two angles is equal to each other. Therefore, assuming that ∠B and ∠C are those equal angles.
Now, given that the measure of ∠A is 40°. Therefore, the sum of the measure of all the angles of the triangle can be written as,
∠A + ∠B + ∠C = 180°
40° + ∠B + ∠C = 180°
40° + ∠B + ∠B = 180°
2 ∠B = 180° - 40°
2 ∠B = 140°
∠B = 140°/2
∠B = 70°
∠B = ∠C = 70°
Hence, the possible measures for ∠B and ∠C are 70°.

A jewelry artist is selling necklaces at an art fair. It costs $200 to rent a booth at the fair. The cost of materials for each necklace is $4.50. The artist is selling the necklaces at $20 each. The jewelry artist wants to make at least a profit of $300. Write an inequality that represents the situation. Make sure to write down the given information from the problem and represent your variables. Show all of your work. B). Find a possible solution for the inequality. Show all of your work and check your answer to make sure that it makes the inequality true.
Answer:
32.25 necklacesStep-by-step explanation:
Given that the expected profit upon deduction of booth rent and material cost is at least $300
Given
let the number of necklaces be x
booth rent= $200
The cost of materials for the necklaces = $4.5x
the selling price for all the necklaces =$20x
total expenses= booth rent+cost of material = 200+4.5x
profit = selling price -total expenses
20x-300>200+4.5x+
B. the possible solution is the value of x i.e the number of necklaces to
be sold to make a profit of $300
20x-300>200+4.5x
20x-4.5x=200+300
15.5x=500
x=500/15.5
x=32.25
The Jewelry artist must have to sell a total of approximately 32.25 necklaces

Angle A and angle B are vertical angles. If m A=(5x-24) and m_B=(3x+24), then find the value of x and the measure of angle A
Answer:
Step-by-step explanation:
If they are vertical angles, they are equal.
5x - 24 = 3x + 24 Add 24 to both sides
5x -24 +24 = 3x + 24 + 24 Combine
5x = 3x + 48 Subtract 3x
5x - 3x = 3x-3x + 48 Combine
2x = 48 Divide by 2
x = 24
