Answer:
1/8
Step-by-step explanation:
The least common multiple of 6, 8, and 3 is 24. That will be the common denominator:
1/6 +5/8 -2/3
= 4/24 +15/24 -16/24
= (4 +15 -16)/24 = 3/24
= 1/8
_____
<em>Alternate solution</em>
You can take advantage of the commutative property of addition and the distributive property to rewrite the problem as ...
5/8 -(2/3 -1/6)
= 5/8 - (4/6 -1/6) . . . . use a common denominator of 6
= 5/8 -3/6
= 5/8 =1/2 . . . . . . . simplify
= 5/8 -4/8 . . . . . . use a common denominator of 8
= 1/8

Answer:
10x - 6
Step-by-step explanation:
x = 3/2
10 * x = 15
10x + 6 = 21
21-6 = 15
Hope this helps : )
Distance=speed times time
if they take the same time, we cal the time , t
b=bike speed
w=walking speed
bikedistnace=17=bt
walkdistance=9=wt
b is 4 more than w
b=4+w
we have
17=bt
9=wt
b=4w
ok so
multiply first equation by 9 and 2nd by 17
153=9bt
153=17wt
set equal
9bt=17wt
divide both sides by t
9b=17w
sub b=4+w for b
9(4+w)=17w
distribute
36+9w=17w
minus 9w both sides
36=8w
divide both sides by 8
4.5=w
he walks 4.5kph
