Answer:
x=8
Step-by-step explanation:
I think you mean find x, not m.
since angle DEG and angle GEF are a linear pair, they equal 180º.
18x-9 + 4x+13 = 180
22x + 4 = 180
subtract 4 from each side
22x = 176
divide each side by 22
x=8
I think the correct answer is B
To solve this, first subtract 3kx from both sides so that both the x variables are on the same side. This will result in: 24=9kx-3kx.
Since 9kx and -3kx are like terms, they will combine and you will get 24=6kx
Now, divide 6k from both sides to isolate x and you get x=24/6k.
However, you notice that 24 and 6k both have a common factor which is 6, so you simplify 24/6k to 4/k which gives you your answer of x=4/k
The answer should be 1.05meters because there are 100cm in a meter.
