What is an expression for subtract 16?
Y = X - 16 X= Y + 16 X is the original value. Y is the new value of the original value - 16.
How do find the original amount after percentage has been taken off?
Let's think money. If 5% was taken off, then the amount paid represents 95% of the original amount. So, to find the original amount, think that 95% of the original amount = paid amount And to solve, divide the amount paid by the percent you paid. In general divide by (100% minus the percent taken off).
How do you figure out the original price of something that you only know the ending total and the percentage off?
We're gonna tear this up. It's simple, but it will take a bit of patience, so buckle up. Ready? Let's go. You don't know the original price. You know the percent off. You know the sale price. We're in business. Let's hammer this thing. Here's how to work the problem....We don't know the original price, but we know that a percentage of it has been deducted from it (that original price) to give us a sale price, okay? Some percent off the original price is the sale price. Here's the trick. Look at the percent off. Now look at 100% minus the percent off. This new percentage represents how much of the original cost the final cost is. Got it? Another way to say that is that our new (calculated) percentage times the original price equals the sale price. Make sense? Let's pick something easy and give it a test drive.Say something costs $9 (that's the sale price), and it was marked down 10%. That means that the original cost minus 10% of the original cost is the final (the sale) price, or the $9. Now check this out. Focus. The discount was 10%, and another way to look at the problem is that the sale price is 100% -10% of the original price, which says that the sale price is 90% of that original price. Again, the sale price is 90% of the original price. See how that works? We use the discount (percentage) and make a calculation to find out how much of the original price the sale price is. We good? Super.As we now have a "new" set of facts to work with, that is, we have the sale price and the percentage of the original price that the sale price represents, we can go for it. The original price (the unknown) times the percentage of that original price that the sale price represents equals the sale price. Let's look at our example.The original price times the percentage of that price the sale price represents equals the sale price. Again, original price times that percentage we calculated equals the sale price. Now to do some math. If the original price times that new percentage equals the sale price, then the original price equals the sale price divided by the percentage. See what we did? We moved the percentage over to the other side of the equation. We divided both sides by the percentage, and it "dropped out" on the one side and appeared on the other. That's because we needed to isolate the original price (so we could solve for it using the other variables). In our example, the original price equals $9 (the sale price) divided by 90% (the percentage of the original price the sale price represents. $9 divided by 90% equals $9 divided by 0.9 which equals $10. The original price of the item was $10, and it was 10% off. The 10% of $10 equals $1, and the sale price is $10 minus $1 which equals $9. Our work checks.One more problem for fun to lock things in. At a 20% off sale, an item sells for $40 (its sale cost). What was its original cost? We know that the $40 represents 80% of the original price (100% -20%). The original price times the 80% equals $40. The original price equals $40 (the sale price) divided by the 80% (the percentage of the original price that the sale price represents). $40 divided by 80% equals $40 divided by 0.8 which equals $50. Our item's original price was $50. Last thing. $50 times 20% equals $10, and $50 minus $10 equals $40. Our work checks.We good? Excellent!I don't understandexplain more carefully
The equation sp -0.15 p represents the sales price s of an item with an original price p after a 15 discount . A T-shirt costs 12. What is the sale price?
It is 10.20
Simplify the following expression 33z-4-20 z-5?
I am assuming that the original equation is 33z-4-20=z-5. Subtract z from both sides. Add 4 to both sides, as well as add 20 to both sides. Divide both sides by 32.

Which algebraic expression is a translation of the verbal expression 6 increased by double a number?
Let the original number be y Therefore the new number is given by the expression 2y + 6
What is simplifying the expression?
Algebraic expressions contain alphabetic symbols as well as numbers. When an algebraic expression is simplified, an equivalent expression is found that is simpler than the original. This usually means that the simplified expression is smaller than the original. There is no standard procedure for simplifying all algebraic expressions because there are so many different kinds of expressions, but they can be grouped into three types: (a) those that can be simplified immediately without any preparation. (b) those that require preparation before being simplified. (c) those that cannot be simplified at all. <3 Tiffany ur welcome
What does it you to evaluate an algebraic expression?
To evaluate an algebraic expression means to simplify the expression as much as possible by replacing the variables in an expression with the numerical values given to you.Ex:Example of Evaluating an Algebraic ExpressionTo evaluate the algebraic expression '4.5 + x' for x = 3.2, we need to replace x with 3.2 and then add. 4.5 + x = 4.5 + 3.2=7.7Solved Example on Evaluating an Algebraic ExpressionEvaluate the algebraic expression p + 3q + 2p - 3q, for p = 2 and q = - 5.Choices:A. 12B. 18C. 3D. 6Correct Answer: DSolution:Step 1: p + 3q + 2p - 3q [Original expression.]Step 2: = (p + 2p) + (3q - 3q) [Group the like terms together.]Step 3: = 3p [Solve within the grouping symbols.]Step 4: = 3 x 2 [Substitute 2 for p.]Step 5: = 6 [Multiply.]
A pair of jeans in on sale for 25 off the original price Which expression represents the sale price If the original price of the jeans is 40 evaulate the expression to find the sale price?
If a pair of jeans cost 25% more than the original price which is 40, then the selling price of a pair of jeans is 50.
Multiplying by the reciprocal of a rational expression is the same as by the original expression?
It is the same as dividing by the original expression.
What does prime factorization and algebraic expression means?
All composite numbers can be expressed as unique products of prime numbers. This is accomplished by dividing the original number and its factors by prime numbers until all the factors are prime. A factor tree can help you visualize this.Example: 210210 Divide by two.105,2 Divide by three.35,3,2 Divide by five.7,5,3,2 Stop. All the factors are prime.2 x 3 x 5 x 7 = 210That's the prime factorization of 210.In mathematics, an algebraic expression is an expression built up from constants, variables, and the algebraic operations (addition, subtraction, multiplication, division and exponentiation by an exponent that is a rational number). For example, 3x2 - 2xy + c is an algebraic expression.
If the common factor x - 2 is divided out of the original expression the reduced expression will be equal to the original expression only when x does not equal?

What is the difference between a cliche and original figurative expression?
A cliche used to be an original figurative expression, but it is so overused that it is no longer creative. An original figurative expression is a unique phrase that is like a simile or metaphor.
What is the value obtained by multiplying a number by itself?
It is the square of the original number. If the original number represents a length, then the square of the original number represents an area of a square with side equal to the original number.
