just count how many letters there are until n - k
<u>Answer:</u>
3x - 2y = 10
<u>Step-by-step explanation:</u>
We are given that the sum of two numbers is 0 and twice the smaller number subtracted from 3 times the larger number is 10.
Assuming x to be the large number and y to be the smaller number we can write an equation to represent this.
Sum of two numbers is 0:

Twice the smaller number subtracted from 3 times the larger number is 10:

Answer:
If:
(1)
And we have to rewrite the following expresion in terms of
:
(2)
Firstly we have to rearrange the right side of equation (2) in terms of
, factorizing by the common factor:
Then, we can substitute
by
:
And set it equal to zero:
>>>>This is the resulting equation
Now, each term of an algebraic expresion (like the equation above) is composed of sign, coefficient, variable and exponent. The terms are separated from each other by the plus sign (+) or the minus sign (-).
In this case, the variable is
and the number that multiplies the variable (the coefficient) is
, whereas the constant (which is the term with no variable) is 
For a triangle, there is a proven inequality<span> that states that</span><span>, the sum of the lengths of any two sides must be greater than or equal to the length of the remaining side
21 + 37 >= 15
58 >= 15
21 + 15 >= 37
36 >= 37
37 + 15 >= 21
52 >= 21
We can see that the second inequality doesn't comply, thus there is not such triangle.</span>
