Example Question #161 : Algebraic Concepts
Divide 200 by 17. The quotient is ; the remainder is . Which is the greater quantity?
(A)
(B)
(A) and (B) are equal
It is impossible to tell which is greater from the information given
(A) is greater
(B) is greater
(B) is greater
and .
and (B) the greater quantity.
Example Question #34 : Equations
If , then how many integers can be substituted for to make the equation a true statement?
Zero
Infinitely many
One
It cannot be determined from the information given
Two
Zero
If , the equation can be restated and solved as follows:
However, no integer can be squared to yield a negative result; therefore, there is no solution, and the correct response is "zero."
Example Question #162 : Algebraic Concepts
How many elements of the set can be substituted for to make the inequality a true statement?
Four
Three
Two
One
None
Three
Three elements of the set—1, 2, and 3—fit this criterion.
Example Question #36 : Equations
Which is greater?
(A)
(B)
(A) is greater
It is impossible to determine which is greater from the information given
(A) and (B) are equal
(B) is greater
(B) is greater
, so .
Therefore , so (B) is greater.
Example Question #163 : Algebraic Concepts
How many elements of the set can be substituted for to make the inequality a true statement?
Four
Five
Two
None
One
None
(Note that the inequality symbol switches here.)
None of the elements of fit this criterion.
Example Question #38 : Equations
If , then how many integers can be substituted for to make the equation a true statement?
Two
One
Infinitely many
Zero
Three
One
If , then the equation can be rewritten and solved as follows:
The only integer that can be substituted for to make this true is , so the correct response is "one".
Example Question #164 : Algebraic Concepts
If a and b are complementary angles, what is the value of a if b is equal to 33 degrees?
Complementary angles add up to 90 degrees. Therefore, .
Given that b is equal to 33 degrees, the equation is:
Next, 33 should be subtracted from each side of the equation.
Therefore, 57 is the correct answer.
Example Question #41 : How To Find The Solution To An Equation
Angles g and h are supplementary. Angle g is 3 times as big as angle h. What is the value of angle h?
If angles g and h are supplementary, then they will add up to 180 degrees.
Given that angle g is 3 times as big as angle h, then:
Therefore,
Example Question #41 : How To Find The Solution To An Equation
Solve for .
In order to solve an equation, you first want to get like terms on the same sides: variables should be on one side and whole numbers on the other. To do this, you must add 6 to both sides of the equation.
The equation will then look like this:
In order to solve for , you must make it so that there is only one of the variable . Since the 3 is multiplied times the variable, you must divide by 3 on both sides of the equation to remove it.
The result you are left with is .
Example Question #165 : Isee Middle Level (Grades 7 8) Quantitative Reasoning
If x and y are angles that are equal to each other and are also complementary, what is the value of x?
If two angles are complementary, then they add up to 90 degrees.
Therefore, .
Given that x and y are equal to each other, .
Thus, .
