You have to find the common divider, which is twelve in this case. So, when you multiply all of them with numbers to get twelve, and add them together, you will get:
12/12 + 6/12 + 9/12 + 2/12 = 29/12.
Definitely irrational because the decimal never repeat
(3) 8
Step-by-step explanation:
Note that ∆ADE is similar to ∆ABC. As such, the ratios of their legs are equal. Also note that AD = AB + BD.
BC/AB = DE/AD
BC/10 = 12/(10 + 5) = 12/15 = 4/5
or
BC = 10(4/5) = 8
3 hours because 39 divided by 13 equals 3 and to check just do 13x3 and it will get you to 39. in conclusion edgar will have to do 3 hours of hard work to get $39
