20-(2x6) +8 divided by 4
2 times 6 = 12
8/4 = 2
20-12+2
It would be 14 not 29
He used PEMDAS in the wrong order
Answer:
See answers below
Step-by-step explanation:
The Bisector Angle Theorem basically states that if a bisector cuts the middle of an angle, the two angles that it creates will be equal to each other.
Therefore:
#7 -> x=38
#8 -> x=144
#9 -> 2x=84 -> x=42
#10 -> x+3=30 -> x=27
Answer:
A) square; rectangle; rhombus
Step-by-step explanation:
Opposite sides are parallel and all sides are the same length. Angles at the corners are 90°, so the figure is a rhombus, rectangle, and square: choice A.
Answer:
x = 1 1/4
Step-by-step explanation:
6x - 1 = -2x + 9
Move the x to one side and the numbers to the other side:
8x = 10
Simplify:
x = 10/8 = 5/4 = 1 1/4
7 lines up and down and 3 lines shaded so 3/7 would be your answer
