There is no single method or strategy for translating mathematical phrases into algebraic expressions. When multiplying a number by a decimal less than one, the product will be smaller than the number being multiplied. ) = His monthly expenses are $1,600. 19.36 y The Math Calculator will evaluate your problem down to a final solution. The keyword here is very obvious; "multiplied by" means that I'll be multiplying (the unknown) by the given value. Example 4: The difference of the productof 7 and w, and the quotient of 2 and v. Answer: In this case, the unknown numbers have been assigned with corresponding variables which are w and v. The key is to recognize that we are going to subtract the product by the quotient of some expressions. The following are easy examples that can help you get familiar with the operations of addition, subtraction, multiplication,and division. v The last step to do is to add the quantity above by 2 to incorporate the remaining part of the phrase increased by 2 . 0000020257 00000 n Choosing the letter w as our variable, the math phrase above can be expressed as the algebraic expression below. 4 Example 1: Write an algebraic expression for the math phrase 3 more than twice a number.

Add a row to your multiplication answer g for. 3, 0.25 Some words are easy, like more than and less than. But others are not as obvious. = Selecting the lettermas our variable, the algebraic expression for this math phrase is simply5m. = Next, we will identify what we are looking for and assign a variable to represent it. When you add, subtract, multiply, or divide the same quantity from both sides of an equation, you still have equality. Translate and solve: The quotient of pp and 99 is 81. k How to solve your inequality. b An algebraic expression is a concise way of describing mathematical objects through the use of numbers, variables (letters), and arithmetic operations such as addition, subtraction, multiplication, and division. Proceed right to left. = 1 + 1 + 1 = 3. 10 For example, $$\frac 12 \times\frac 34 = \frac 38.$$ Both factors are less than 1, and the product is less than both factors. 46 The sum (use plus symbol) of twice a number and 3 can be written as 2x+3. p 38 ) ) p Malik is planning a six-day summer vacation trip. Emiliano thinks x=40x=40 is the solution to the equation 12x=8012x=80. 54, 20 18 10 the solution of quadratic equations. 4 z + ( Insert a decimal point in the product so it has the same number of decimal places equal to the total from step 1. In the following exercises, solve each equation using the Division and Multiplication Properties of Equality and check the solution. Then, we will solve the inequality. t 7 How many first-run movies can he watch if he wants to keep his monthly bill to be a maximum of $100? We will restate the problem in one sentence to make it easy to translate into an inequality. So to undo the division, we will need to multiply by 4. v x y 1 10 52.60, 63.90 = 3 ( In the following exercises, graph each inequality on the number line and write in interval notation. = In other words, QuickMath will try to find solutions satisfying both inequalities at once. $2.50 times the number of invitations minus $650 is at least $2,800. Translate and solve: The quotient of qq and 88 is 72. = 9 linear equation. v = 3 Does the inequality stay the same when we divide or multiply by a negative number? x 0000009207 00000 n 7 ) What was the original price of the car? 75. So triple a number means 3y. d x 77, 23 used to show that a number is part of the graph, and a parenthesis is used to 4 The company offered him $48,000 per year plus 3.5% of his total sales. 12 59 60 7 0 + 0 = 0 = Similarly, when we describe an expression in words that includes a variable, we're describing an algebraic expression (an expression with a variable). 12 = 3x: Half of a number is twenty. v Solve:1822=12xx4x.1822=12xx4x. That is why i'm going back to the basics of it to learn it again and improve my skills. = u 3 85 This calculator also shows the work. + Translate and solve: The sum of five-eighths and x is one-fourth. The sum of nine-tenths and g is two-thirds. Solve: 6(r2)12=30.6(r2)12=30. 4 For example, starting with the true statement - 3 < 5 and multiplying c Multiply the tens digit in the bottom number by each digit in the top number. The difference of q and one-eighth is three-fourths. However, you may have been given some explicit directions in IXL that asked you to write the terms in a certain order. 1 = q x 7 = y 10 n x 4 Put the 0 in Ones place Jakes water bill is $24.80 per month plus $2.20 per ccf (hundred cubic feet) of water.
