Two angles are supplementary if their sum is 180°. The larger angle measures three degrees more than twice the measure of a smaller
angle. If x represents the measure of the smaller angle and these two angles are supplementary, find the measure of each angle.
Answers
Smaller Angle= 59°
Large Angle= 121°
EXPLANATION:
You can start with setting it up like this
Small angle=X
Large angle=Y
We also know the large angle is 3 more then two times the small angle, it can be shown like this
y=2x+3
We also know that supplementary angles add up to 180°. So we now have 2 equations.
y=2x+3
x+y=180
Plug the first equation into the second one. Then solve for x
x+(2x+3)=180
3x=177
x=59
Then plug x into the first equation and solve for y.
y=2(59)+3
y=121
So…
Smaller Angle= 59
Large Angle= 121

which lines are parallel if angle 4 = angle 5? justify your answer
Answers
r and s are the parallel lines, if ∠4 equals ∠5.
Given,
The figure with,
Four lines: Line r, Line s, Line l and Line m.
Angles: ∠1, ∠2, ∠3, ∠4, ∠5, ∠6, ∠7 and ∠8
Here, we have to find the parallel lines when ∠4 = ∠5
Lets see:
Angle 1 and angle 4 are the same because the opposite angles created by two crossing lines are identical. As a result, angle 1 also equals angle 5.
The corresponding angles are identical when two parallel lines cross across a line. To put it another way, if r and s are parallel, the angles created when l intersects r and s are same. Angle 1 equals Angle 5, Angle 2 equals Angle 6, etc. We can infer that r and s are parallel since we know that angle 1 Equals angle 5.
So, we can conclude that if ∠4 equals ∠5, then r and s are the parallel lines.

Answer:
Maggie did not combine like terms correctly when she subtracted 7x from both sides of the equation. Here is a correct solution:

3. In a competitive exam, Gopi gets 4 marks for each correct answer and -2 for each wrong answer. If he gives 32 correct answers and 8 wrong answers, what will be his total score?
Answers
7 × 12 = 72 satisfies the closure property of multiplication, the other integer when the sum is - 38 and one integer is - 22 will be - 16 and the total score for Gopi will be 112 marks.
1)
Closure property of multiplication:
It states that if two real numbers a and b are multiplied, then the product will be a real number as well.
We have 7 × 12 = 72
7, 12 and 72 all are real numbers.
So, it is a closure property under multiplication.
2)
Sum = - 38
a = - 22
We need to find b
a + b = - 38
- 22 + b = - 38
b = - 38 + 22
b = - 16
3)
1 correct answer = 4 marks
1 incorrect answer = - 2 marks
Number of correct answers = 32
Number of incorrect answers = 8
Total score = 32 × 4 + (- 2) × 8
= 128 - 16
= 112 marks.
Therefore, we get that, 7 × 12 = 72 satisfies the closure property of multiplication, the other integer when the sum is - 38 and one integer is - 22 will be - 16 and the total score for Gopi will be 112 marks.

A dealer purchased an old car for 70,000. He spent 17,500 on its repair and painting. Due to lack of demand he had to dispose it at a loss of 12%. What was the selling price of the car?
Answers
The selling price of the car is 77,000.
First, let's define what a selling price is.
The selling price is the price the customer pays to purchase the good.
Selling price = Cost price – (100% Loss)/100
We are told that the car cost 70,000 and that 17,500 was lost (12%) in repairs and painting.
The car's total cost is equal to 70,000 + 17,500 = 87,500.
So, the car's cost price is 87,500.
Selling price = 100/12/100 x cost price
= 100/12/100 x 87,500
= 0.88 x 87,500
= 77,000
Consequently, the car is being sold for $77,000.

Answers
We can simplify the numerical expression to get:
(2/5)*(14 - 27) + (2⁵/16) = -16/5
How to simplify the numerical expression?Here we have the expression:
(2/5)*(14 - 27) + (2⁵/16)
Let's simplify the term in the right first, we know that:
2⁵ = 2*2*2*2*2 = 4*4*2 = 16*2 = 32
Replacing that we get:
(2⁵/16) = 32/16 = 2
Then we get:
(2/5)*(14 - 27) + (2⁵/16) = (2/5)*(14 - 27) + 2
Now we can simplify the term in the left:
(2/5)*(14 - 27) = (2/5)*(-13) = -26/5
Replacing that we get:
(2/5)*(14 - 27) + 2 = -26/5 + 2 = -26/5 + 10/5 = -16/5

Explain why the statement line LR ≅ line RL and ∠CBA ≅ ∠ABC are both true by the Reflexive Property of Congruence.
Answers
The reflective Property of Congruence states that any figure is congruent with itself, therefore line LR ≅ line RL and ∠CBA ≅ ∠ABC.
What is congruence?If it is possible to superimpose one geometric figure on the other so that their entire surface coincides, that geometric figure is said to be congruent or to be in the relation of congruence.
Reflexive Property of Congruence said that an angle line segment or any shape is congruent with itself.
For example, a line segment with a length of 5 meters will be the same as another line with 5 meters or a copy of that line so both will be congruent.
Line LR and RL are the same in length thus line LR ≅ line RL.
Angle CBA and angle ABC are the same thus ∠CBA ≅ ∠ABC.
Hence "The reflective Property of Congruence states that any figure is congruent with itself, therefore line LR ≅ line RL and ∠CBA ≅ ∠ABC".

On a certain hot summer's day, 273 people used the public swimming pool. The daily prices are $1.25 for children and $2.50 for adults. The receipts for admission totaled $528.75. How many children and how many adults swam at the public pool that day?
Answers
The number of children is 123 and the number of adults is 150 for that day.
According to the question,
We have the following information:
273 people used the public swimming pool.
Price for children = $1.25
Price for adults = $2.50
The total amount received = $528.75
Now, let's take the number of children to be x and the number of adults to be y on that day.
So, we have the following expression:
x + y = 273
x = (273-y) .... (1)
1.25x + 2.50y = 528.75
Now, putting the value of x from equation 1:
1.25(273-y) + 2.50y = 528.75
341.25 - 1.25y + 2.50y = 528.75
341.25 + 1.25y = 528.75
1.25y = 528.75-341.25
1.25y = 187.5
y = 187.5/1.25
y = 150
Now, putting this value of y in equation 1, we will find the value of x:
x = 273-y
x = 273-150
x = 123
Hence, the number of children is 123 and the number of adults is 150 on that particular day.

Given that,
In the picture there is a scissor.
The scissor has intersecting lines with angles 1,2,3,4.
∠1=159° and ∠3 is 159°.
We have to find the angles ∠2 and ∠4.
Two straight lines that intersect at the same location are said to be intersecting lines. The junction point is the place where two intersecting lines meet. Four angles are created when two lines cross. The four angles added together always equal 360 degrees. There is a unique connection between the angles created when lines intersect.
The straight line has 180°
∠1+∠2=180°
159°+∠2=180°
∠2=180°-159°
∠2=21°
Now,
∠3+∠4=180°
159°+∠4=180°
∠4=180°-159°
∠4=21°
Therefore, the angle ∠2=21° and ∠4=21°.
