Solve for c:
-7c - 2 = \( \frac{c}{-7} \)

46% Answer Correctly

	-6\(\frac{3}{10}\)
	-\(\frac{7}{24}\)
	1\(\frac{2}{13}\)
	\(\frac{8}{57}\)

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.

-7c - 2 = \( \frac{c}{-7} \)
-7 x (-7c - 2) = c
(-7 x -7c) + (-7 x -2) = c
49c + 14 = c
49c + 14 - c = 0
49c - c = -14
48c = -14
c = \( \frac{-14}{48} \)
c = -\(\frac{7}{24}\)

If a = 4, b = 5, c = 4, and d = 8, what is the perimeter of this quadrilateral?

88% Answer Correctly

	21
	16
	20
	29

Solution

Perimeter is equal to the sum of the four sides:

p = a + b + c + d
p = 4 + 5 + 4 + 8
p = 21

If AD = 12 and BD = 8, AB = ?

75% Answer Correctly

	5
	19
	4
	1

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 = 12 - 8
AB = 4

A coordinate grid is composed of which of the following?

88% Answer Correctly

	all of these
	origin
	y-axis
	x-axis

Solution

The coordinate grid is composed of a horizontal x-axis and a vertical y-axis. The center of the grid, where the x-axis and y-axis meet, is called the origin.

What is the circumference of a circle with a radius of 7?

71% Answer Correctly

	34π
	12π
	14π
	1π

Solution

The formula for circumference is circle diameter x π. Circle diameter is 2 x radius:

c = πd
c = π(2 * r)
c = π(2 * 7)
c = 14π
