Answer:
It is given that, AB and P Q are parallel lines.Line segment CR and D S, intersect the two lines.
Line segment CR and D S ,are Transversal to parallel lines, AB and P Q.
⇒∠C + ∠ R=180°
⇒90°+∠ R=180°
∠ R=180°-90°
∠R=90°
Similarly, ∠S=90°
→∠R+∠S=90°+90°=180°
As, sum of interior angles on the same side of transversal is 180°, so lines are Parallel.
→CR║DS
Also, AB║CD→CD║RS.
If in a Quadrilateral, opposite sides are parallel, then it is a Parallelogram,and also each interior angle has measure 90°, so it is a Rectangle.
In a rectangle opposite sides are equal.

What is the solution to the system of equations?
y=1/2x-6
x=-4
O (8,4)
O (4, -8)
O (4,4)
O (4,-4)
Answer:
(-4,-8)
Step-by-step explanation:
The solution to the system of equations is,
⇒ (- 4, - 8)
What is an expression?Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
We have to given that;
The expressions are,
⇒ y = 1/2x - 6
⇒ x = - 4
Now, We can simplify the expression for y as;
⇒ y = 1/2x - 6
Put x = - 4;
⇒ y = 1/2 × - 4 - 6
⇒y = - 2 - 6
⇒ y = - 8
Thus, The solution to the system of equations is,
⇒ (- 4, - 8)

Which of the following is equivalent to (3x + 1)(x - 2)?
3x2 – 2
3x2 - 6x + x – 2
3x2 + 5x – 2
4x + 1
(3x + 1) (x - 2)
= 3x(x - 2) + 1(x - 2)
= 3x² - 6x + x - 2
= 3x² - 5x - 2
What is the quotient 5/8 + 1/5?
Answer:
33/40
Step-by-step explanation:
cross multiply
5 x 5 = 25
8 x 1 = 8
25 + 8 = 33 (our numerator)
8 x 5 = 40 (our least common denominator)

Sydney purchased a used car for $3,500. Her state charges a 5% tax for the car, $85 for registration, $60 for a new title certificate, and $35 for a state safety and emissions inspection. How much does Sydney need to pay for these extra charges, not including the price of the car?
Answer:
$355
Step-by-step explanation:
85+60+35=180
5% of 3,500 is 175
175+180=355
so if i did the math right that means the answer is $355
Hopefully the right answer
can someone explain how to solve this?

Clark bought a 3.2 Ib bag of potatoes , which had 10 potatoes. How many potatoes would there be in a 10 Ib bag?
9514 1404 393
Answer:
31
Step-by-step explanation:
If we assume the number of potatoes is proportional to the weight, then we can write the equation ...
n/10 = 10/3.2
n = 100/3.2 = 31.25 . . . . . . . multiply by 10
There may be 31 potatoes in a 10-lb bag.
−7+11p=3p−47
what is p?
Answer:
p= -5
Step-by-step explanation:
because UwU and also −7+11p=3p−47
−7+11p=3p+−47
11p−7=3p−47
11p−7−3p=3p−47−3p
8p−7=−47 8p−7+7=−47+7
8p=−40 8p /8 = −40 /8
Answer:
P= -5

Kimberly is deciding between two cell phone plans. The first plan has a $50 sign-up
fee and costs $20 per month. The second plan has a $30 sign-up fee and costs $25 per
month. After how many months will the costs be the same for the two phone plans?
Answer:
2month and 2 weeks
Step-by-step explanation:
We are told that the first plan has a $50 sign-up
fee and costs $20 per month.
let the number of months be x, and the total cost be y
y=20x+50---------1
The second plan has a $30 sign-up fee and costs $25 per
let the number of months be x, and the total cost be y
y=30x+25---------2
Equate the two equations we have
20x+50=30x+25
solve for x, collect like terms
50-25=30x-20x
25=10x
divide both sides by 10
x= 25/10
x=2.5 months
x= 2month and 2 weeks

Kelly has a pool in her backyard, and she wants to build a fence around the entire area. Kelly's backyard is 14 meters wide and 15 meters long. It costs $6.63 per meter to install a wooden fence. How much would it cost to put a wooden fence around Kelly's backyard?
Answer:
$384.54Step-by-step explanation:
Dimensions of the backyard is 14 m by 15 m
The length of the fence is the perimeter of the backyard.
P = 2(l +w)P = 2(15 + 14) = 2(29) = 58 mOne meter of the fence costs $6.63
Cost of the entire fence is:
58*$6.63 = $384.54Answer:
perimeter of backyard=2(15+14)=58m
it cost
1m=$6.63
58m=$6.63×58=$384.54
therefore it cost
$384.54 to put a wooden fence around Kelly's backyard.

Angelina received two discounts on a $50 pair of shoes. The discounts were taken off one after the other. If she paid
$30 for the shoes, what was the percent discount for each coupon? Is there only one answer to this question?
Answer:
There are many solutions.
Step-by-step explanation:
A 20% discount on $50 takes us to $40. A 25% discount on the $40 takes us to 30%.
We can also do a 4% discount to bring us to $48, followed by a 62.5% discount, to get to $30.

A person earns 23,000 one year and gets a 5% raise in salary. Calculate the new yearly salary using a percent greater than 100
Answer:
24,150
Step-by-step explanation:
Given that :
Salary earned this year = 23,000
Percentage Raise in salary for the new year = 5%
The new yearly salary can be obtained thus ;
(100% + percentage raise in salary) * salary earned this year
(100% + 5%) * 23,000
105% * 23000
1.05 * 23000
24,150
