The history museum is less that 9 4/5 miles. 9/10 means that the 9 3/4 mile is broken up into 10 equal parts and the distance to the museum is only 9 of those parts. 9 3/4 (9.8) divided by 10 equals 98/100 (.98)
98/100 x 9 = 882/100 or 8.82
Justin's house is 8.82 miles from the museum.
So the equation is x + 2x + 5= 29
Here are the steps -5 -5
-----------------------
3x = 24
Divide both sides by 3 so you get
x = 8
Then look back at the question, the second number has to be twice that number plus 5
So the 1st number is 8 The second # is 2(8)+5= 21
