Normal Equations
Resolve the following equation:
3x - 1 = 8
x = 3
The phrase used to describe part of an equation. (I.E. [2x] [+ 4] [-3] = [11])
Term.
Write the Proportion for the following question:
In a rail yard, 2 out of every 30 train cars are engines. If there are 75 train cars, how many train cars are engines?
2 / 30 = x / 75
Resolve the following inequality:
x - (3)(5) < 4
x < 19
The six words which PEMDAS stands for.
Parenthesis, Exponent, Multiplication, Division, Addition, Subtraction.
Resolve the following equation:
5x - 1 = 24
x = 5
The thing that you must do to the variable in order to solve an equation.
Isolate the variable.
Write the inequality for this question:
The difference of twice a number and two is less than ten.
2n - 2 < 10
Resolve the following inequality:
x - 12 > 3
x > 15
The first part of this operation that must be done:
10 + 14 + 5 - 10 = ?
[10 + 14]
Resolve the following equation:
2 + (2b - 4) = 20
b = 11
This tiny number is placed next to a number like this 53, and is used to represent how many times that number is multiplied. (I.E. 53 = 5 * 5 * 5 = 125)
Exponent.
Write an inequality for this word problem:
Four times a number is more than the sum of the number and twelve.
4n > n + 12
Resolve the following inequality:
3b < 9
b < 3
The direction a problem is worked from, and towards.
(I.E. from up-to-down.)
Resolve the following equation:
-16 - 10 - 2d = 5d + 7
d = -11
If you do something to one side of the equation, you must do this to the other sides:
The exact same thing.
Write a the inequality for this word problem:
Six less than the product of three and a number is less than nine.
3n - 6 > 9
Resolve the following inequality:
2 + 10x - 4 < 18 + 5x
x < 4
The first part of this operation that must be done:
(10 + 6) / 2 - 3 = ?
(10 + 6)
Resolve the following equation:
3(n - 1) = 17 - n
n = 5
Something you can do when two terms possess the same variable with the same exponent. It helps you save time and trouble.
Combine like terms.
Write an proportion for this word problem:
A captain gives bay area tours. He gave 60 tours during the last 80 days. How many tours should he expect to give during the next 400 days?
60 / 80 = x / 400
Resolve the following inequality:
8 < p + 17 < 33
-9 < p < 16
