Write an algebraic expression of: Justin can type 4 times as many words as Justin.
4j
Solve for the variable:
What is a function table?
A function table is a table of order pairs that follow a rule. The function rule describes the relationship between the input and the output.
Solve this equation for the variable:
Solve
4x + 2
What are some words in Algebra for exponents?
To the power, squared, cubed.
Solve
45 + 5x
Solve 5(2f + 2b + c)
10f + 10b + 5c
Which are some ways that multiplication is shown in algebraic expressions?
Example: Five times a number
Explain the associative property
When you multiply or add only, the groupings don't matter
What is an inequality?
When two quantities are not equal
What is the order of operations?
GEMS G rouping symbols E xponents M ultiply / Divide S ubtract/ Add
Steps to solve for a variable in a multiplication
The inverse or opposite of multiplication is division. To solve: 1. Divide both sides by the same number to keep the equation equal. 2. This will leave the variable by itself.
What are some key words in Algebra for division?
Half, each, split, share, quotient, per, every.
In an equation how do you solve for a variable?
You isolate the VARIABLE or get it by itself. "ISOLATING THE VARIABLE".
What is an equation?
When values of two mathematical expressions are equal. This is indicated by the = sign.
Solve for the variable:
Five times d increased by 8
5d + 8
Which value is the dependent variable and which is the independent variable?
The input is the INDEPENDENT variable and the output is the DEPENDENT variable.
What are like terms in algebra?
Terms that have the same variable
The algebraic expression for: w raised to the fifth power and then increased by 4:
When you see a number next to a variable, what do you do? 3x
You multiply the number by the variable if you know the variable's value.
Ten less than the product of 15 and c
15c - 10
What is an algebraic expression?
It contains AT LEAST one variable and AT LEAST one mathematical operation.
What does EVALUATE mean in Algebra?
Evaluate means to find the value of the variables. To solve an algebraic expression.
What is the algebraic expression for: the sum of b and 5?
b + 5
What is a term in algebra?
One part of an expression. It can be just a number.
Steps to solve for a variable in a division equation
The inverse or opposite of division is multiplication. To solve: 1. Multiply both sides by the same number to keep the equation equal. 2. This will leave the variable by itself.
Explain the identity property
You get the same number when you multiply by 1 or add zero. 3 + 0 = 3 2 x 1 = 2
What is the algebraic expression for: the quotient of c and d?
Evaluate if m = 3
Solution: 19
Explain the commutative property
The order doesn't matter when you multiply or add 3 + 4 = 4 + 3
What is a coefficient in algebra?
The number beside the variable in a term.
Steps to solve for a variable in a subtraction or an addition
The inverse or opposite of subtraction is addition and the opposite of addition is subtraction. To solve: 1. Add the same number to both sides or subtract. 2. This balances the equation. 3. This will leave the variable by itself
What are some key words in Algebra for multiplication?
Double, product, times, twice, each, of, per, every.
What are some words in Algebra for subtraction?
Decrease, minus, ate, fewer, spent, left, how much more, less, difference, how much left.
Steps to simplify EXPRESSIONS
1. Distribute if necessary 2. Draw different shapes around like terms. 3. Use the coefficients to combine the like terms.
What are some key words in Algebra for addition?
Combine, sum, more, plus, all, together, total, in all, increase.
What is a variable?
A variable is a symbol, usually a letter, that REPRESENTS a number. b + 5 = 11
Write your own words for:
Tatiana had m candy and Victoria had m times as much. Tatiana ate 9 pieces of candy.
How do you read an ordered pair of a function on a graph?
(x, y) First the x and then the y.
What operation would you do first in an equation?
According to GEMS, First solve the addition in the parenthesis, Then the exponent. Next, divide. Finally, subtract. Solution: 22
Write an algebraic expression of: Marcus has 4 more dollars than Yaseen.
y + 4
Evaluate 5m + 3 If m = 6
Substitute the letter m for its value: 5(6) + 3 = 33
Solve 5m + 3m + 3 + n - m + 6n + 8
7m +7n + 11
Solve for the variable
Evaluate if t = 3 and u = 8
Solution: 6
Write an algebraic expression of the following problem: Nathan and Sam combined their baseball cards and then sold 10 of them.
n + s - 10
