They biked 120 km
they bussed 80 km
because 120 + 80 = 200 and 120 is 40 more than 80
Answer:
40 customers
Step-by-step explanation:
40% brown,
25% black
20% blonde
15% red
100% = 160
(40* 160)/ 100
6400 / 100 = 64
40% = 64 customers
(15 * 160)/100
2400/100 = 24
15% = 24 customers
64 customers - 24 customers =40 customers.
Step-by-step explanation:
x+y=12
3×+y=20
×=12-y
3 (12-y)+y=20
36-3y+y=20
36-4y=20
-4y=20-36
-4y= -16
y =16÷4
y=4
×+y=12
×+4=12
×=12-4
×=8
therefoer;y=4,x=8
The answer will be
x=root 121
x=11
