Answer:
B. x = 20
Step-by-step explanation:
angles on a straight line are supplementary
therefore, 6x+9 + 2x+11 = 180
so, 8x+20=180
8x = 160
x = 20
Answer: a
Step-by-step explanation:
The answer to this question is "D". To understand where to shade, just plug in (0,0) to the linear equation. when you plug in (0,0) it makes your last option true
Answer:
x=10
5x=50
2x=20
Step-by-step explanation:
110+5x+2x = 180 combine like terms and move the constants to the same side
7x=70
x = 10
5(10) = 50
2(10) = 20
Answer:
B. 96 units
Step-by-step explanation:
DA is 6 units and HE is 36 units. There are the same side, but HE is 6 times larger.
AB is 16 units, but since all the sides on the left shape are 6 times larger, EF has to be 16*6, which is 96 units.
Hope this helps
