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.

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.

25 - 3x = 40 1/3x - 12 = -3
Answer:
25 - 3x = 40 x=-5
1/3x - 12 = -3 x=27
Step-by-step explanation:
25-3x=40 -> subtract 25 each side .... -3x=15 -> divide -3 each side...... x= -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
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)

−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

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)

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
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.
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
You need to make at least 360 wraps for a party. You can make 9 wraps per minute.
How long will it take you to make the number of wraps you need?
In two or more complete sentences write and solve an inequality for the situation and explain how you will solve the inequality.
Answer:
It will take 40 minutes for me to make the 360 wraps that I need.
9x ≥ 360 ⇒ x ≥ 40
Step-by-step explanation:
I have to make at least 360 wraps for a party.
I can make 9 wraps per minute.
So, it will take minutes for me to make the 360 wraps that I need.
If I work for x minutes to make wraps, then I will be able to make 9x wraps.
So, the inequality that models the given condition is
9x ≥ 360
⇒ x ≥ 40 {Dividing both sides by 9}
Therefore, I need to work at least 40 minutes to reach my goal. (Answer)

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
