Answer:
I believe the answer is 20
Step-by-step explanation:
She rides from her house to school which is 4 kilometers. Then she rides from school to the library which is 6 kilometers. The total so far is 10 kilometers.The question then says she takes the same route home so you would multiple 10 by 2 so the answer should be 20 kilometers
We can use proportions
12/x = 10/5
12*5 = 10x
60 = 10x
x = 6
Check
12/6 = 10/5
2 = 2

❖ Mai has $4.90 left.
Add $4.35 and $5.25 to get the total amount that she spent:
$4.35 + $5.25 = $9.60
Then subtract to get the amount of money left:
$14.50 - $9.60 = $4.90
