Question 1: - An expressions is simply a set of terms (3x + 2xy)

Answer:

An Equation Question 2: - To solve an equation, you need to manipulate the terms on each side to isolate the variable,

Answer:

Inequalities

Question 3: Probability equation

Answer:

Probability = desired outcomes/ total number of outcomes

Question 4: - Divide the numerator by the denominator.

-The resulting whole number is placed to the left of the fraction, and the remainder becomes the new numerator; the denominator does not change. the result is called a mixed number

Answer:

Turning a mixed number into an improper fraction

Question 5: -16oz

-0.454kg

Answer:

• cal=

Question 6: 1

Answer:

V

Question 7: Distance word problems

Answer:

• Distance = speed x time
• Time = distance/speed
• Speed = distance/ time

Question 8: Finding percent change from amount of change and original amt.

Answer:

-percent change = amt. of change/ original amt.-Percents should always be expressed as a decimal in this equation.-To convert a decimal into a percentage value, simply multiply it by 100

Question 9: a fraction whose numerator is larger than the denominator

Answer:

proper fraction

Question 10: -4 quarts

-8 pints -16 cups -3.785 Liters

Answer:

• mile=

Question 11: -5280 ft

-1.61km

Answer:

• hour

Question 12: Equals key words

Answer:

• Is, was, are, amounts to, and were

Question 13: > means greater than: the expression left of the symbol is larger than the expression on the right

Answer:

Less than

Question 14: Finding original amt. from amt of change and percent change

Answer:

• Original amt. = amt. of change/ percent change

-Percents should always be expressed as a decimal in this equation.-To convert a decimal into a percentage value, simply multiply it by 100

Question 15: 500

Answer:

M Question 16: - Collect like terms on each side as you would for a regular equation: -7x + 2 < 6- 5x --> -2x < 4 The direction of the sign switches when you divide by a negative number -2x < 4 --> x > -2

Answer:

Absolute Value

Question 17: A whole number and a fraction together.

Answer:

Turning a improper fraction to a proper fraction

Question 18: a fraction with a numerator smaller than the denominator

Answer:

Mixed numbers

Question 19: Finding the 4th value in a proportion

Answer:

• Often you will be given 3 of the values in a proportion and asked to find the 4th.
• you can solve for the missing variable by cross-multiplying

-Multiply the numerator of each fraction by the denominator of the other to get an equation with no fractions

• You can then solve the equation using basic algebra.

Question 20: Proportions

Answer:

• An equation which states that 2 ratios are equal.
• Usually written as 2 fractions joined by an equal sign, but can also be written using colons (a:b::c:d)
• In a proportion, the units must be the same in both numerators and in both denominators.

Question 21: - When variables occur in both the numerator and denominator of a fraction, they cancel each other out.

• A fraction with variables in its simplest form will not have the same variable on the top and

bottom

Answer:

Solving Equations

Question 22: Finding percent from part and whole

Answer:

Percent = part/whole -Percents should always be expressed as a decimal in this equation.-To convert a decimal into a percentage value, simply multiply it by 100

Question 23: Percent Change Problems

Answer:

• Percent change problems will ask you to calculate how much a given quantity changed.

-the problems are solved in a similar way to regular percent problems, except that instead of using the part, you'll use the amount of change -The sign of the amount of change is important -If the original amount has increased, the change will be positive -If the original amount has decreased, the change will be negative.
