Answer:
$8
Step-by-step explanation:
if each person pays $12
then total cost is $24
so 150km --> $24
1km --> 24/150
1km --> $0.16
so 250 km --> $0.16 * 250 =$40
if 5 people travel, each person has to give $40 / 5 = $8
Answer:
a. 21: 45
d. 63: 135
Step-by-step explanation:
Ratio or Relationship of two quantities is the result of comparing two quantities.
Such a comparison could be indicated as a reason, in four different ways, in this way:
1)a: b
2)a ÷ b
3)a/b
d)The reason for a is a b.
Equivalent ratios can be used to show the same relationship between two quantities. Remember that the word "equivalent" means the same.
Problem development
We observe what are the equivalent relationships 7:15 and conclude that they are the following:
a.To find the equivalent ratio, we divide the numerator and denominator by the same number , In this case we divide by 3:
21: 45 = 21/45 = 21÷3 /45÷3 = 7/15
d.To find the equivalent ratio, we divide the numerator and denominator by the same number , In this case we divide by 9:
63: 135= 63/135 = 63÷9 /135÷9= 7/15

Answer:
x = 100
Step-by-step explanation:
(x - 20) + x = 180
2x - 20 = 180
<u> + 20 +20</u>
2x = 200
x = 200/2
x = 100
