Answer:
Even.
Step-by-step explanation:
They will be even.
All even numbers, by definition, are divisible by 2.
We can write 3 even numbers as 2m, 2n and 2p.
So the sum = 2m + 2n + 2p
= 2(m + n + p).
This proves it because the sum is a multiple of 2 and must be even.
8% write left handed.
90+60=150
9+3=12
12/150=.08
The <em>correct answers</em> are:
A) Both can be solved by graphing;
C) Both can be solved by substitution; and
D) Both have solutions at the points of intersection.
Explanation:
Just as a system of linear equations can be solved by graphing, a system of quadratic equations can as well. We graph both equations. We then look for the intersection points of the graphs; these intersection points will be the solutions to the system.
We can also solve the system by substitution. If we can get one variable isolated, we can substitute this into the other equation to solve.
Answer: 8+7
Step-by-step explanation: 3+5+7 is equivalent to 8+7 because if you add the both of them you’ll get the same exact answer which is 15
