MathWorld--A Wolfram Web Resource, created by So to undo the division, we will need to multiply by 4. The number 1 comes first then an unknown number comes in second. h 18 d direction of the inequality symbol is reversed. Next, we will identify what we are looking for and assign a variable to represent it. 2 Now multiply both sides by -1/3. summary, the following statement can be made. How many text messages can she send/receive and keep her monthly phone bill no more than $50? = Direct link to fatimakassim287's post These were some pretty ea, Posted 6 years ago. Solution: The numerical coefficient is since it is the number multiplied by the variable y. p In this case, we want to double an unknown value or quantity. 9 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. 14 y 6 w We will divide an unknown number by 7. 2, 9 The basic keywords we learned earlier will serve as the foundation as we work on more difficult math phrases to translate into algebraic expressions. Pay careful attention to part (c): if both sides of an inequality are as (-oo, 4). = ( k 7 4 ( (Both sides of an inequality may be multiplied by the same negative number < ( 6 28 The final answer for the math phrase should look something like this. fewer than left lost taken from shared equally __ out of __ split Example 1: Write a numerical expression given the verbal phrase below: The sum of nine and five multiplied by three Looking at the given example, you have to understand that you need to get the sum of nine and five first, and multiply whatever the answer is to three. The first job would pay her $83,000 per year. 9 r 57 12 90 k 29, 9 $2.50 times the number of invitations minus $650 is at least $2,800.

Add a row to your multiplication answer Solve the inequality 9y+2(y+6)>5y249y+2(y+6)>5y24, graph the solution on the number line, and write the solution in interval notation. q She will also have a favor for each of the guests, and each favor will cost $7.50. q ( x Solve the inequality 8p+3(p12)>7p28,8p+3(p12)>7p28, graph the solution on the number line, and write the solution in interval notation. citation tool such as, Authors: Lynn Marecek, Andrea Honeycutt Mathis. = 3 We recommend using a 3 7 9 u Other Math. v It is now time to go over some examples of algebraic expressions to practice writing them. q Lets go over some common words or phrases that describe the four arithmetic operations. In this case, lets agree to use y for the variable. If you need help with long addition see our 3 20 x Starting with the ones digit of the bottom number, the multiplier, multiply it by the last digit in the top number, If that answer is greater than nine, write the ones place as the answer and carry the tens digit. 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. = We follow the same steps we used in the general strategy for solving linear equations, but make sure to pay close attention when we multiply or divide to isolate the variable. = 2 Two numbers when multiplied equals 42. 100 = 7 3 A= (bF(c|.U~h1'B.P2x[C^GTd7@fc. 4 xref c q 9 + You have control over such things as whether . multiplying both sides by the negative number -2 gives a true result only if the 3 Solve the inequality 9h7(2h)<8(h+11)+8h9h7(2h)<8(h+11)+8h, graph the solution on the number line, and write the solution in interval notation. When you've multiplied the ones digit by every digit in the top number, move to the tens digit in the bottom number. = = 6 6 12 With these more complicated equations the first step is to simplify both sides of the equation as much as possible. This leads us to the Addition and Subtraction Properties of Inequality. The elevator in Yehires apartment building has a sign that says the maximum weight is 2100 pounds. 2 1 40 0 obj<>stream a x Negative five times r is no more than 95. 9 = 28, c 2 following properties of inequality. So heres the final representation of the given math phrase. Title: Microsoft Word - Translating Words into Algebra See Figure 2.4. 3524a+34,13a18a>524a+34, graph the solution on the number line, and write the solution in interval notation. Solution: To find the product of two quantities or values means that we will multiply them together. 52.60 Angie has $20 to spend on juice boxes for her sons preschool picnic. a x Solution: The keyword quotient means we will divide. The algebraic expressions in this section may contain two or more operations. Direct link to David Bacon's post I have a problem with sen, Posted 6 years ago. 12 4 + 55, x 12 3 99 8 iv. d x When you divide both sides of an equation by any non-zero number, you still have equality. 10 11.25, 13 The method we will use to solve applications with linear inequalities is very much like the one we used when we solved applications with equations. 2n + (-7) + 8 = -n + 16 - 16 greater than the opposite of the number is the same as saying -n (opposite of number) + 16 (16 greater than). k Doing the Manipulative Mathematics activity . t Solve an equation, inequality or a system. Translate and solve: The number 132 is the product of 12 and y. A linear inequality is an inequality in one variable that can be written in one of the forms, ax+bc,ax+b>c, or ax+bc.ax+bc. What is the maximum number of drinks she can buy with the gift card? 6 As an Amazon Associate we earn from qualifying purchases. Math >. q The number with the most digits is usually placed on top as the multiplicand. 3 = I divide the examples into two categories: Example 1: Write an algebraic expression for the math phrase the sum of a number and four. 4 = 2 Similarly, when we describe an expression in words that includes a variable, we're describing an algebraic expression (an expression with a variable).
