Question 2: Division of fractions by fractions




What is the value of (3/4) (2/3)?


A) 9/8


B) 8/9


C) 6/12


D) 12/6


The correct answer is A) 9/8.


To solve this problem, you need to invert (flip) the second fraction and multiply it by the first fraction. You can also simplify the fractions before or after multiplying them. Here is how to do it:


(3/4) (2/3) = (3/4) x (3/2) = (3 x 3)/(4 x 2) = 9/8 Question 5: Negative numbers and absolute value




What is the value of -7 + 4 - -7 - 4 ?


A) -10


B) -6


C) 6


D) 10


The correct answer is C) 6.


To solve this problem, you need to apply the absolute value function, which means taking the distance of a number from zero. You also need to perform the addition and subtraction inside the parentheses first. Here is how to do it:


-7 + 4 - -7 - 4 = -3 - -11 = 3 - 11 = -8


Question 6: Writing and evaluating algebraic expressions




Write an algebraic expression for the phrase "three times the sum of x and y". Then, evaluate the expression when x = 2 and y = 5.


A) 3x + y; 11


B) 3(x + y); 21


C) x + 3y; 17


D) x + y; 7


The correct answer is B) 3(x + y); 21.


To write an algebraic expression, you need to use symbols such as letters, numbers, and parentheses to represent quantities and operations. To evaluate an algebraic expression, you need to substitute the given values for the variables and simplify using the order of operations. Here is how to do it:


3(x + y) = 3(2 + 5) = 3(7) = 21 Question 7: Solving one-step equations and inequalities




Solve for x: 2x + 5 = 13. Then, write an inequality that shows the values of x that are less than the solution.


A) x = 4; x


B) x = 4; x 4


C) x = 5; x


D) x = 5; x 5


The correct answer is A) x = 4; x


To solve a one-step equation, you need to use the inverse operation to isolate the variable. To write an inequality, you need to use a symbol such as , , or to show the relationship between the variable and a number. Here is how to do it:


2x + 5 = 13 -5 -5 _______ 2x = 8 /2 /2 _______ x = 4 x


Question 8: Area of parallelograms and triangles




Find the area of a parallelogram with a base of 12 cm and a height of 9 cm. Then, find the area of a triangle with the same base and height.


A) 108 cm^2; 54 cm^2


B) 108 cm^2; 36 cm^2


C) 96 cm^2; 48 cm^2


D) 96 cm^2; 32 cm^2


The correct answer is A) 108 cm^2; 54 cm^2.


To find the area of a parallelogram, you need to multiply the base and the height. To find the area of a triangle, you need to multiply the base and the height and divide by two. Here is how to do it:


Area of parallelogram = base x height = 12 cm x 9 cm = 108 cm^2 Area of triangle = (base x height) / 2 = (12 cm x 9 cm) / 2 = (108 cm^2) / 2 = 54 cm^2 Question 9: Distance and polygons on the coordinate plane




Find the distance between the points A(2, 5) and B(8, 1) on the coordinate plane. Then, find the perimeter of the quadrilateral ABCD with vertices A(2, 5), B(8, 1), C(6, -3), and D(0, -1).


A) 7.21 units; 24.84 units


B) 7.21 units; 22.84 units


C) 6.32 units; 24.84 units


D) 6.32 units; 22.84 units


The correct answer is A) 7.21 units; 24.84 units.


To find the distance between two points on the coordinate plane, you need to use the distance formula, which is derived from the Pythagorean theorem. To find the perimeter of a polygon on the coordinate plane, you need to add up the lengths of all its sides using the distance formula. Here is how to do it:


Distance between A and B = ((x2 - x1)^2 + (y2 - y1)^2) = ((8 - 2)^2 + (1 - 5)^2) = (36 + 16) = (52) = 7.21 units Perimeter of ABCD = AB + BC + CD + DA = ((8 - 2)^2 + (1 - 5)^2) + ((6 - 8)^2 + (-3 - 1)^2) + ((0 - 6)^2 + (-1 + 3)^2) + ((2 - 0)^2 + (5 + 1)^2) = (52) + (20) + (40) + (40) = 7.21 + 4.47 + 6.32 + 6.32 = 24.84 units Question 10: Volume and surface area of 3D figures




Find the volume and surface area of a cube with a side length of 5 cm.


A) 125 cm^3; 150 cm^2


B) 125 cm^3; 100 cm^2


C) 100 cm^3; 150 cm^2


D) 100 cm^3; 100 cm^2


The correct answer is A) 125 cm^3; 150 cm^2.


To find the volume of a cube, you need to multiply the length, width, and height of the cube, which are all equal to the side length. To find the surface area of a cube, you need to multiply the area of one face of the cube by six, since there are six faces in a cube. Here is how to do it:


Volume of cube = side x side x side = 5 cm x 5 cm x 5 cm = 125 cm^3 Surface area of cube = 6 x (side x side) = 6 x (5 cm x 5 cm) = 6 x (25 cm^2) = 150 cm^2

Frequently Asked Questions




What is the difference between a ratio and a percent?




A ratio is a way of comparing two quantities using fractions or decimals. For example, the ratio of boys to girls in a class can be written as 12/15 or 0.8. A percent is a special type of ratio that compares a part to a whole using hundredths. For example, the percent of boys in a class can be written as 80%, which means 80 out of 100 or 80/100.


What is the difference between an expression and an equation?




An expression is a combination of numbers, variables, and operations that represents a quantity. For example, 2x + 5 is an expression. An equation is a statement that shows that two expressions are equal. For example, 2x + 5 = 13 is an equation.


What is the difference between an inequality and an equation?




An inequality is a statement that shows that two expressions are not equal. For example, 2x + 5


What is the difference between a parallelogram and a rectangle?




A parallelogram is a quadrilateral with two pairs of parallel sides. For example, a rhombus and a trapezoid are parallelograms. A rectangle is a special type of parallelogram with four right angles. For example, a square and an oblong are rectangles.


What is the difference between a cube and a prism?




A cube is a 3D figure with six square faces, eight vertices, and twelve edges. A prism is a 3D figure with two congruent polygonal bases and rectangular lateral faces. A cube is a special type of prism with square bases.
