We have a system of equations 2x - 4y = 5 and 6x - 3y = 10.
We want to eliminate one variable when we add up the equations.
If we want to eliminate the x variable, we need to multiply the top, bottom or both of the equations with a number that when the equations are added together will eliminate the x variable.
Multiply the top equation by -3.
-3(2x - 4y) = 5 * -3
-6x + 12y = -15
Now when we add the two equations together, the x's will be eliminated.
-6x + 12y = -15
6x + 6y = 10
18y = -5
The x's were eliminated.
For a number to be divisible by 14 it needs to be both divisible by 7 and 2 which are factors of 14. Every time you have a number (x) to check if it is divisible by some larger number you find the factor of that larger number and check is the x divisible by both.
Answer: it cannot be divisible by 14.
Answer:
Ans: 36
Step-by-step explanation:
just separate it into three rectangles and use the formula
A=l*b
and at last add all of them
Answer:
true
Step-by-step explanation:
a prime number is an odd number.
If you add 1 to an odd number, it will become an even number, then it is divisible by 2.
The answer would be 460 centimeters
