Answer:
y=2
Step-by-step explanation:
7y-1=13
+1 +1
7y=14
/7 /7
y=2
Answer: 13 and 8
Step-by-step explanation:
13+8=21
13-8=5
All I did was trial and error. Plus, it helps to set up an equation : x+x=21, x-x=5
Answer:
Step-by-step explanation:
I input the equation and got this graph, hope this helped! :)
Sum of two monomials is not necessarily always a monomial.
For example:
Suppose we have two monomials as 2x and 5x.
Adding 2x+5x , we get 7x.
So if two monomials are both like terms then their sum will be a monomial.
Suppose we have two monomials as 3y and 4x
Now these are both monomials but unlike, so we cannot add them together and sum would be 3y + 4x , which is a binomial.
So if we have like terms then the sum is monomial but if we have unlike terms sum is binomial.
Product of monomials:
suppose we have 2x and 5y,
Product : 2x*5y = 10xy ( which is a monomial)
So yes product of two monomials is always a monomial.
To get the decimal think of 3/8 as a division question -3 divided by 8
3/8=0.375
now times the decimal by 100
0.375 * 100=37.5
so the answer is going to be 37.5%
