Resolve to do so
5x3=15
5x9=45
3+9=12
15+45=5x12
15+45=60
5x12=60
60=60
Which property is shown I did not understand but I think with the result 60 = 60 alone, but you will understand if you can not send me a comment, so I'll try to make you understand =)

Nostrana [21]

Answer:

He must lose 4.4 pounds per week.

Step-by-step explanation:

Buffalo Bill currently weighs 202 lb. He wants to weigh 180 lbs for his reunion.

This means that he needs to lose 202 - 180 = 22 lb.

35 days from today.

Each week has 7 days. So this is 35/7 = 5 weeks from now.

How many pounds per week must he lose?

22 pounds in 5 weeks, that is 22/5 = 4.4 pounds per week.

All we need to do is plug the numbers into the equation.

$2(3)--1=0\\6--1=0\\7\neq0$

Not A.

$2(2)--4=0\\4--4=0\\8\neq0$

Not B.

$2(1)-2=0\\0=0$

C is the correct answer

Two towns, Ancaster and Dundas, are 4 km and 6 km, respectively, from an old railroad line that has been made into a bike trail.

serg [7]

Okay, so first you draw a picture and let x be the distance from point D to the rest stop. Then the distance from point to the rest stop is 8 - x

You know that the length of the new trail is y + z, where y is the distance from Ancaster to the rest stop and z is the distance from Dundas to the rest stop.

Now by the Pythagorean theorem, y^2 = 4^2 + x^2 and z^2 = 6^2 + (8 - x) ^2

So take square roots of these, add them, and minimize.

Note: I am assuming the path is perfectly straight, otherwise this approach fails.
