So you add 13+5=18
Then you do 144/18=8
8x13=104 8x5=40
104+40=144✅
Answer= 104 : 40
Answer:
28
Step-by-step explanation:
Question Image is attached.
Triangle BED and Triangle CFD are similar.
We can let the length of BD be 5x and DC 7x
We also know BC = 48, thus we can write:
5x + 7x = 48
12x = 48
x = 4
Now, Since DC = 7x, we plug in x = 4 into it.
DC = 7x
DC = 7(4)
DC = 28
Length of DC is 28
4 miles because 15 x 4 is 60 which is an hour and takes 15 mins to walk 1 mile

So, the blank should have ^4
