The first step you would take is to combine all like terms in the parentheses.
5a - 4a = a
Then you would multiply 2 by a, which would equal 2a.
Finally, combine all like terms (all terms with a), to get 8a. (2a + 6a = 8a)
Hope this helps!
Hello,
If the numbers are a and b and (a>=b)
Are-you asking a/b ?
If yes,
a+b=20
a-b=4
==>2a=24
==>a=12 and b=20-12=8
a/b=12/8=3/2
<u>Bus:</u>
40 min = 36 miles
1 min = 36 ÷ 40 = 0.9 mile
<u>Car:</u>
1 min = 0.9 x 1.4 = 1.26 miles
<u>Total distance covered by both vehicles in 1 min: </u>
1.26 + 0.9 = 2.16 miles
<u>Time needed for both of them to cover 36km:</u>
36 ÷ 2.16 = 16 2/3 min
Answer: They will meet 16 2/3 mins after they have started.
