ok one of my problems that i have and idk exactly how to do it and its very easy but i cant think of it and neither can my sister. so its an equation problem...
a person must burn 3500 Calories to lose one pound of weight.
so the problem is write an equation that represents the number of Calories a person would have to burn a day to lose four pounds in two weeks??
second one is how many Calories would the person have to burn each day?

answer to question 2 is 1000.
answer to q 1 is-
in a day calories to loose is x
no. of punds to loose- 4 pounds
no. of calories to loose for 1 pound- 3500
total no. of cals to loose- 3500 * 4 = 140000
no. of calories to loose in a day = total calories to loose/no. of days
equation is x=4*3500/14
thus 1000 calories are to be lost In ONE day so as to loose 140000 calories in 14 days.
did i help?

Since a person burns 3500 cals to lose 1 lb of weight, to lose 4 lbs, they must burn 4*3500 calories, or 14,000 calories. However, they're doing this over a period of 2 weeks, or 14 days. So to find the number of calories they need to burn per day, just divide 14,000 by 14. The answer is 1000 calories.

3500calories = 1lb weight
it's a ratio. so do 3500 calories / 1lb = x calories/4lb
cross multiply
3500*4 = x
x= 14,000 calories
this is in two weeks...2 weeks = 14 days.
so, 14,000/14 days = 1,000
tada!! :)

no of calories to be burnt for losing 1 pound=3500
no of calories to be burnt for losing 4 lbs=3500*4(direct variation)
=14000
calories to be burnt in 2 weeks or 14 days=14000 calories
calories to be burnt /day=14000/14=1000 calories

Divide 14,000 by 14.
