It isn't equal, and any proof that they are equal is flawed.
Assuming the given is written as: 4y/6y6=20 First off, this can be simplified down to: 2/3y5=20 Since this is an indirect proof, we must first assume the opposite of what you are trying to prove. You are trying to prove that y is not equal to -1. Let y=-1 If this was done, then the following substitution would be made: 2/3(-1)5=20 2/3(-1)=20 2/(-3)=20 -2/3 =20 Clearly, -2/3 does not equal 20. Since y=-1 causes a mathematically impossible statement, then y cannot equal -1. As far as formatting it for a formal indirect proof, I'm no help there. Different teachers like different formatting.
You have to prove it by showing what the mean of the five numbers is. First, you add up the five numbers, which is equal to 15. Then, you divide the sum by 5, which is 3, and not 8.
YES ... to prove it, divide both the numerator and the denominator of 5/15 by 5 and you will get 1/3

To prove that 1 kg is equal to 1000 grams, you can use the definition of the kilogram as the base unit of mass in the metric system. By definition, 1 kilogram is equal to 1000 grams. This relationship is established and accepted in the International System of Units (SI).

Mathematical Induction is a process uses in College Algebra It can be used to prove that a sequence is equal to an equation For Example: 1+3+5+7+n+2=2n+1 there are 3 steps to mathematical induction the first includes proving that the equation is true for n=1 the second includes substituting k for every n-term the third involves substituting k+1 for every k-term to prove that both sides are equal
It has 3 sides 2 of which are equal in length It has 3 angles 2 of which are the same size
1 and 3/4 is equal to 1.75
no, 3 and 1/3 is equal to 33/10!
