42 x 8 - 236 + 50 x 2 - 200
Answers
Answer:0!
Step-by-step explanation:
Answer: 180
Step-by-step explanation:
Since they're a bunch of signs I would use PEMDAS
P = parentheses
E = Exponent
M = multiplication or D = Division
A = Addition or S = Subtraction
Problem:
42 x 8 – 236 + 50 x 2 – 20
Note: for example if you're up to multiplication OR division that means whatever you see first here's an example
66 x 4 ÷ 28
You see multiplication first so use it if it's the other way around use division first. THE SAME GOES WITH ADDITION AND SUBTRACTION!!!!

A clothing store is having a sale. All items are on sale for 35% off the original price. Create an equation in terms of p, the original price of an item, to show the sale price of an item before any sales tax.
Answers
Answer:
P ÷ 35% = X
Step-by-step explanation:
Because P is the original answer, it needs to be divided by 35% because it 35% off, so it would equal X, the original item price discounted.
Hope this helps!
The correct equation in terms of p, the original price of an item, to show the sale price of an item before any sales tax is,
⇒ Sale price = p - 35% of p
What is mean by Percentage?A number or ratio that can be expressed as a fraction of 100 or a relative value indicating hundredth part of any quantity is called percentage.
We have to given that;
A clothing store is having a sale.
And, All items are on sale for 35% off the original price.
Now,
Let the original price of items = p
Then, The sale price is,
Sale price = p - 35% of p
= p - 35p/100
= p - 7p/20
= 13p/20
Thus, The correct equation in terms of p, the original price of an item, to show the sale price of an item before any sales tax is,
⇒ Sale price = p - 35% of p

Answer:
First, find the area of the surface of the shed. Two walls will have an area of 14 x 8 and two walls will have an area of 18 x 10. We get the equation 2(14x8) + 2(10x8) = 224 + 160 = 384 square feet
Next, divide the square footage of the shed's surface by 250 to find how many gallons of paint are needed. 384/250 = 1.54 gallons of paint (rounded to the nearest hundredth)
For the triangle questions, remember that the area of a triangle is [tex]\frac{(base)(height)}{2}[/tex]
Sara is taking a test made up of multiple-choice and open-ended questions. The multiple-choice questions have a value of 4 points each, and the open-ended questions have a value of 5 points each. If Sara has already answered 10 multiple-choice questions correctly, which inequality best describes the amount of open-ended questions Sara must answer correctly to earn more than 70 points?
x greater-than 6
x less-than 6
x greater-than 12
x less-than 12
Answers
Answer:
To find this, you must find the total number of points Sara has scored already. She has answered 10 multiple choice questions which are 4 points each. This means that Sara has scored 40 points so far.
If Sara wants to score at least 70 points, she needs to score at least 30 more points. To find how many open-ended questions she needs to answer, you need to divide the remaining number of points by the number of points an open-ended question is worth. The number we get will be x.
30/5 = 6
This means Sara must complete at least 6 open-ended questions to score 70. Now, all we have to do is figure out which inequality sign to use. Since Sara wants to score more than 70 points, it should be the "greater than" sign.
Your answer is: x>6

Emmanuels Work:
7(x-2)=91
distribute the 7 by multiplying both x and -2 by it
7x-14=91
add 14 to both sides
7x=105
divide both sides by 7
x=15
Mauricio's Work:
7(x-2)=91
to get rid of the 7 multiplication, divide both sides by 7
x-2=13
add 2 to both sides
x=15
