Literal & Other Equations Review Khan Academy Topics
Very Impressive:@ the Khan Academy
For Tuesday & Wednesday only… 1154 mins. 19.83 hours
Formulas & Vocabulary Page1. Dimension:
Length & Width.The dimensions of a 2-dimensional object are?The dimensions of a 3-dimensional object are?. Length, Width, & Height
3. Formula for the volume of a rectangular 3-dimensional object is:
The amount of space, measured in cubic units, (lwh) that an object or substance occupies.
2. Volume:
Length x Width x Height
The measure of a thing in a given direction.
Most grocery products are “sold by weight, not by volume” Why?
Formulas:
Class Notes Section of your
notebook, pls.
b. Find the height of a cylinder with volume of 3140 feet and radius of 10 ft.
Class Notes:Tips for Solving Literal & Other
Equations:1. If the variable you are solving for is inside the parenthesis, you must distribute first.
9p = 3(k + 5) for k
2. If the variable you are solving for is outside the parenthesis, simply perform the opposite operation.9 = k(p + 5) for k
3. When clearing fractions, if the denominator being multiplied has two or more terms, it must be distributed on the other side.
5k( 2p + 4) = 9 = for p
Literal Equations:
We need to separate the ‘k’ from the 5 in this case. Solve the equation.
Class Notes:
Tips for Solving Literal & Other Equations:
4. Always check to see if every term has something in common. You can then factor the common part out.3kp – 7km – 9k – 1 = -7p +
10 for k first
3kp – 7km – 9k = -7p + 11
Then,
k(3p – 7m – 9) = -7p + 11
Now What?
k= -7p + 11 (3p – 7m – 9)
Class Notes:
Tips for Solving Literal & Other Equations:
5. If an entire term can be factored out, replace it inside the parenthesis with a ‘1’2p + 8px = ?
2p(1 + 4x) check by distributing the 2p again.
6. When solving fractional equations, you may have to clear fractions more than once.
Class Notes:
4 – 2x = 𝟔−𝟑 𝒙𝟑
20 – 10x =5
Complete the first step.Now we distribute the....
Solve for x.
Tips for Solving Literal & Other Equations:
7. Two equal fractions is called a proportion.Proportions can be solved by cross multiplying.The following is not a proportion. How must this
problem be solved?Finish It
Class Notes:
= solve

Solve for a: Q = 3a + 5ac
Solve for h: A = ah - bh
Warm-Up: Literal Equations
What can be factored out of both terms?
Find the missing dimension:
P = 60
L = 19
3(x + 6) + 2x – 6 = 8x -2(3x – 6) -2 Same Rules; don’t do anything
