Answer:

60 chickens

Step-by-step explanation:

We assume the 140 refers to the number animals (heads, noses, bodies, whatever). If all of those were chickens, there would be 280 legs. There are 160 legs more than that.

Since each pig that replaces a chicken adds 2 legs, there must be 160/2 = 80 pigs. That leaves 140 -80 = 60 chickens.

15 is 25% of what number

Sergio [31]

<span>The answer is 60. Let x be the number we are looking for. So x is 100% and we know that 15 is 25%. Make a proportion: x : 100% = 15 : 25%. Cross the products: x * 25% = 15 * 100%. x * 25% = 1500%. x = 1500% : 25%. x = 60. Thus, 60 is 100%, and 15 is 25% of 60. </span>

Find the solution to the system. Write your solution as an ordered pair (x,y)

Studentka2010 [4]

Answer:

Infinitely many

Step-by-step explanation:

If we multiply the equation x-3y=7 by 3, we get 3x-9y=21, which is also the second equation. That means the two lines are on top of each other, meaning infinite many solutions.
