Multiple Choice

Which of the following angles is  $90\degree$  ?

•  $\angle FGH$  

•  $\angle KJL$  

•  $\angle PJK$  

•  $\angle EGH$  

Multiple Choice

Is the solution below correct?
5d = 2d - 18
-2d   -2d
3d = -18
d = 6

• Yes
• No

Multiple Choice

Find the error in the problem below
19 - 2k = 3k - 1
     +3k   +3k
19 + 1k = -1
-19           -19
k = -20

• They should have divided by 1 for the last step
• They should add 19 instead of subtracting 19
• I can not find an error
• Instead of adding 3k they should subtract 3k

Multiple Choice

Solve for x:
8x - 10 = -34

• 4
• 3
• -3
• -24

Multiple Choice

Solve for the variable. 3x=-27

• x=9

• x=-30

• x=-9

• x=-24

Multiple Choice

Solve for w:
-6w + 1 = -11

• 2
• 1.2
• 12
• -2

Multiple Choice

Solve for n:
n+2=-14-n

• 6
• 8
• -8

Multiple Choice

3x + 12 + 9x = 72

• 5

• 6

• 7

• -7

Multiple Choice

• x+40 = 3x because both are x's using the clue

• x+40 + 3x = 180 supplementary angles because one is an x other is an O using the clue

Multiple Choice

• angle 3 = angle 7 because vertical angles

• angle 3 = angle 7 corresponding angles

• angle 3 = angle 7 supplementary angles

• angle 3 is not equal angle 7 supplementary angles

Multiple Choice

• 6y = 120 (corresponding angles)

• 6y = 120 (both are x from the clue)

• 6y + 120 = 180 ( 1 is a X and other is a O when i se the clue - supplementary angles)

Multiple Choice

• angle 2 = 115 (both are x's using the clue)

• angle 2 + 115 = 180 (one is a X other is a O - supplementary angles)

Multiple Choice

• 8x + 2 + 70 = 60 (interior angles of a triangle)

• 8x +2 +70 + 60 = 180 ( interior angles of a triangle)

• 8x + 2 = 70 + 60 ( exterior angles and interior angles

Multiple Choice

• 109 = 8x + 2 - 8x +11 ( exterior angle and interior angles

• 109 = 8x + 2 + 8x + 11 (exterior angle and interior angles of a triangle)

• 109 + 8x +2 + 8x + 11 = 180 ( sum of interior angles of a triangle)

Multiple Choice
