Answer:
631139.04 kilometers in 3 years
Step-by-step explanation:
Let x = how many kilometers she walk
y = time (minutes)
Since she walks 4km in 10 minutes.
x = 4, y = 10
(4,10)
But how many minutes if she walk only a kilometer? Divide x and y by 4.
(1,2.5)
She walks a kilometer under 2.5 minutes.
Now finding rate of changes.

Since m = 2.5
and of course, the function should be proportional so the equation should be y = mx.

Since time should be minutes instead of years.
Since 3 years = 1577847.6 minutes

Divide both sides by 2.5

Answer:
Please check the explanation.
Step-by-step explanation:
Given the expression
5.2v - (30 ÷ 6) + 12
<u>9) We need to determine which part of the expression represents a quotient?</u>
We know that when we divide one rational expression by another, the result would be termed as 'quotient'.
Here, it is clear that:
(30 ÷ 6) represents the expression part for a quotient.
When we divide 30 by 6, we get the result 5 which would be the quotient of the expression 30 ÷ 6.
10. Which part of the expression represents a product of two factors?
We know that when a multiply two number, we get the product. The multiplying numbers are the factors of the product.
For example, 4 × 9 = 36 therefore, 4 and 9 are the factors of 36.
In our case, 5.2v represents a product of two factors 5.2 and v. In other words, 5.2 and v are the factors of the product of 5.2v.

Answer:
in the form 81 and 324
Step-by-step explanation:
Divide 405 in the ratio 3: 12.
3x+12x=405
15x=405
x=405:15
x=27
=> 3*27 and 12*27
81 and 324
in the form 81 and 324
