Solve for c:
9c + 3 = 6 + c

58% Answer Correctly

	\(\frac{3}{8}\)
	1\(\frac{1}{6}\)
	-\(\frac{1}{2}\)
	4\(\frac{1}{2}\)

Solution

To solve this equation, repeatedly do the same thing to both sides of the equation until the variable is isolated on one side of the equal sign and the answer on the other.

9c + 3 = 6 + c
9c = 6 + c - 3
9c - c = 6 - 3
8c = 3
c = \( \frac{3}{8} \)
c = \(\frac{3}{8}\)

If AD = 25 and BD = 16, AB = ?

75% Answer Correctly

	7
	9
	12
	14

Solution

The entire length of this line is represented by AD which is AB + BD:

AD = AB + BD

Solving for AB:

AB = AD - BD
AB = 25 - 16
AB = 9

If the base of this triangle is 5 and the height is 9, what is the area?

58% Answer Correctly

	22\(\frac{1}{2}\)
	32
	50
	30

Solution

The area of a triangle is equal to ½ base x height:

a = ½bh
a = ½ x 5 x 9 = \( \frac{45}{2} \) = 22\(\frac{1}{2}\)

The formula for the area of a circle is which of the following?

76% Answer Correctly

	a = π r
	a = π r²
	a = π d
	a = π d²

Solution

The circumference of a circle is the distance around its perimeter and equals π (approx. 3.14159) x diameter: c = π d. The area of a circle is π x (radius)² : a = π r².

A quadrilateral is a shape with __________ sides.

90% Answer Correctly

	3
	5
	2
	4

Solution

A quadrilateral is a shape with four sides. The perimeter of a quadrilateral is the sum of the lengths of its four sides.
