Answer:
It's actually the 3rd choice because AE is double DB so to find x we must double AE and set it equals to DB.
Answer:
means that he picks any of the 5 choices at random
Step-by-step explanation:
"guesses" means that the student will pick at random any of the 5 choices that he has with the hope to select the right one. Then we are assuming that any of the 5 choices are equally likely to be the correct one , so there is no answer that is closest to be the right one ( we do not have any information that can judge whether any answer is more likely to be the right one with respect to the others).
Ur answer is B- 4/5 because when u subtract them u get 0.8 and then u have to turn it as a fraction then it will be 8/10 then u simplify it and u get 4/5.
Hope u get it right!
12x=4(x+5) (multiplying 4 by each argument in the parenhesis)
12x=4x+20 /-4x both sides
8x=20 /:8 divide both sides by 8

15x-3(3x+4)=6 (-3 times each argument in the parenthesis)
15x-9x-12=6
6x-12=6 /+12 both sides
6x=18 /:6 divide both sides by 6
x=3
3x-5x+10=36
-2x+10=36 /-10 both sides
-2x=26 /:(-2) divide both sides by -2
x=-13
2(x+3)=x+10
2x+6=x+10 /-x
x+6=10 /-6
x=4
