A grown man will burn roughly 120 calories for each mile run. How many calories will be burned when a grown man runs 6.5 miles (that is info for my questions)my questions: What is the independent quantity?
What is the dependent quantity?
Write an eqaution to solve the problem?
And Solve the eqaution?

The independent quantity is 120, as it will never change.

The dependent quantity is x, or 6.5 in this case, because that number will vary

120x = y. Where x is the amount of miles ran, and y is the total calories burned

Since we know that x=6.5, we can replace x for 6.5.

120(6.5)=y

780=y

i think it's ф or x=6,-6

step-by-step explanation:

-x^2=-36

x^2=-36

ф

or

if you mean by : -(x^2)=-36

it'll be: x^2=36

x=6,x=-6

hope it'll ! have a good day!

you for asking!

the 8 in 8,420 is in the thousands place so it's value is 8 thousand.

the 8 in 6,870 is in the hundreds place so it's value is 8 hundred.

divide 8000 by 800 to find the answer:

8000 / 800 = 10

the 8 in 8,420 is 10 times greater than the 8 in 6,870
