Answer:

k = 324

Step-by-step explanation:

Y varies inversely as x

Let k be the constant of variation

Y = k/ x

Y= 36 and x= 9

Substitute the value of Y and x

36 = k/9

Make k the subject of the formula

k= 36*9

k =324

Find the GCF 4x^5y^3+8x^4y^4+4x^3y^2
Alekssandra [29.7K]

4x^5y^3+8x^4y^4+4x^3y^2

GCF is the greatest common factor

We take GCF of numbers  first and then we take GCF for variables

GCF of 4, 8, 4 is 4 because all the numbers are divisible by 4

For variable, lowest exponent is our GCF

GCF of x^5+x^4+x^3 is x^3

GCF of y^3+y^4+y^2 is y^2

So GCF is 4x^3y^2

Sergeu [11.5K]

Answer:

Mina took 2,986 steps on the third hour.

Step-by-step explanation:

With the information provided, you know that Mina took a total of 9,245 steps in three hours and as you know the quantity of steps she took on the first and second hour, you can subtract the steps she took on the first and second hour from the total amount of steps to determine the steps she took on the third hour:

9,245-2,387-3,872=2,986

According to this, the answer is that Mina took 2,986 steps on the third hour.
