<span>1. </span><span>Original ratio of the bike and
scooter is equals to :
=> 3 : 4, where 3 is the bike and 4 is the scooter
=> 48 bikes
=> original order = 64 scooter
=> 64 / 4 = 16
however, bike is more popular than scooter, so they changed it into new ratio:
=> 5 : 2 , where 5 is equals to bikes and 2 is equals to scooter.
=> 5 x 16 = 80 bikes
=> 2 x 16 = 32 scooter.</span>
So 50 miles/60 minutes and you basically just convert it
you want to divided by 10 so you will get
5miles/6minutes
and then multiply both by 3 and you will get 18
so it takes 18 minutes
8(7x-1)+4(x+5)
multiply; 8 x 7=
56x + -1 + 4x +5
reorder the terms;
-1 + 5 + 56x + 4x
Combine like terms; -1 + 5 = 4
4 + 56x + 4x
Combine like terms again; 56x + 4x = 60x
4 + 60x
Answer:
18
Step-by-step explanation:
x = 3
2(3) + 12
6 + 12
18
Answer: 68
Step-by-step explanation: Complementary angles are angles that add up to 90. So, you need to do 90-22=68.
