Answer:
x=28°
Step-by-step explanation:
supplementary angles equal 180°
So:
3x+2x+x+12=180°
6x+12=180
6x=168
x=28°
Therefore:
3x:
3(28)=84°
2x:
2(28)=26°
x+12:
28+12=40°
Answer:
15
Step-by-step explanation:
20 precent is 1/5 of one hundred so if 20% is 3 that means that 3*5=15 so the answer is 15
Up, right, down, left, up
Well, you can estimate the decimal. For example if you have 1.35678 you can round the three to a four because there is a 5 beside it so the estimated decimal would be 1.4, 1.4 as a fraction would be 1 4/10 which can be simplified down to 1 2/5.
Answer: X- 4y - 12=0
step by step explanation:
First, move the constant to the left by adding its opposite to both sides
x-4y -12 = 12-12 =
X-4y-12 = 0
So the answer is X- 4y - 12=0
