College Placement Test-Math Questions
And Answers 100% Guaranteed Success.
terms - correct answer. 12, -3, x(variable), 15y, 11xy, -4x^2, -a,
either a single number or variable, or numbers and variables multiplied together.
Terms are separated by + or − signs
Coefficients - correct answer. # associated with each of those terms is called
coefficient(12, -3, 1,15, 11, -4, -1, 3
expression - correct answer. adding 1 or more terms together
linear equation - correct answer. equation has =sign. ex of linear eq: 4x+3=11
a linear equation is one that is dependent only on constants and a variable raised to the
first power. For example, y=6x+2y=6x+2 is linear because it has no squares, cubes,
square roots, sines, etc. Linear equations can always be manipulated to take this form:
ax+b=0
rule - correct answer. if you do something to one side of the equation, you must do it
to the other
how to solve a linear equation-4 steps - correct answer. 1.) get rid of
parentheses&combine like terms
2.) get all terms w/ the variable on one side& all other terms to other side - correct
answer. 3.) isolate variable by dividing
4.) check answer - correct answer.
, percents - correct answer. per=dividing, cents=100, like in a dollar
41% over 100 =.41 - correct answer. take decimal place, move it two places to the
right
solving percent equations - correct answer. "of"=multiply
"is"= equals - correct answer. "out of"=division
96% of what #is 72? - correct answer. "what" or "what #" = x(the unknown)
.96 times x =72
.96x over .96 =72 over .96, x= 72 divided by .96
x=75
7 is 4% of what #? - correct answer. 7 = .04 times x
ratios - correct answer. A comparison of two quantities by division
proportions - correct answer. An equation stating that two ratios are equal.
unit ratio - correct answer. A unit rate where the denominator is one unit
cross products - correct answer. The product of the numerator of one ratio and the
denominator of the other ratio, can equal to each other and if they do, then it is
proportional
unit conversions - correct answer. distance=yards, feet, meters, centimeters,
millimeters, miles, kilometers
linear equations - correct answer. an equation between two variables that gives a
straight line when plotted on a graph
variable. 1st power. no second or higher power on any #s
common denominator - correct answer. A denominator that is the same in two or more
fractions.
clear the fraction - correct answer. multiply whole equation by CD
x-coordinate - correct answer. the first number in an ordered pair
x-coordinate - correct answer. corresponds to a number on the x-axis
