Week 4

Problem #1

Is the number shown in parentheses a solution for the given equation?

x + 8= -12 (-6)

No

Problem #2

Solve for x and check your result.

10x = -100

x = -100/10

x = -10

10 * (-10) = -100

Problem #3

Solve for x and check your result

= 2

x = 3 * 2

x = 6

6/3 = 2

Problem #4

Solve for x and check your result

8- 5x = -7

-5x = -8 - 7

-5x = -15

x = -15 / (-5)

x = 3

8 - 5 * 3 = 8 - 15 = -7

Problem #5

Solve the literal equation for the indicated variable

K = (for m) Energy

mv2 = K

m = K/ v2

Problem #6

Solve the equation for x, and check your result:

2(x + 3) = -6

x + 3 = -6/2

x + 3 = -3

x = -3 -3

x = -6

2 * (-6 + 3) = 2 * (-3) = -6

Problem #7

Solve the equation for x, and check your result

7(3x + 11) = 9(3 - 6x)

21x + 77 = 27 - 54x

21x +54x = 27 - 77

75x = -50

3x = -2

x = -2/3

7 ( 3 * (-2/3) + 11) = 9 (3 - 6 * (-2/3))

7 * 9 = 9 * 7

Problem #8

Identify the indicated quantity in the statement

The base in the statement "40% of 600 is 240."

600 * 40/100 = 600 * 4/10 = 60 * 4 = 240

Problem #9

Carlotta received a monthly raise of $162.50. If this represented

a 6.5% increase, what was her monthly salary before the raise?

x * 6.5/100 = 162.5

x = 162.5 / (6.5/100)

= (162.5 * 100)/6.5

= $2,500

Problem #10

Graph the solution of the follow inequality

x < -2

Shaded area is the graph.
