Answer:
Convert the fraction to a decimal number. The fraction bar between the top number (numerator) and the bottom number (denominator) means "divided by." ...
Multiply by 100 to convert decimal number to percent. 0.25 × 100 = 25%
Step-by-step explanation:
The coefficients of x are already opposites, so you can simply add the two equations to eliminate x.
... (-7x +3y) + (7x -2y) = (14) + (-14)
... y = 0 . . . . . . . simplify
... -7x + 3·0 = 14 . . . . substitute the value of x into the first equation
.. x = 14/(-7) = -2
The solution is (x, y) = (-2, 0).
For this case, we have the following equation of the second degree:
If we divide between 2 on both sides of the equation, we will have:
Where:
The solutions will come from:
Substituting:
So, we have:
Answer:
Option A
Option E
Answer:
Explanation:
It is EXACTLY how it sounds, and of course, you must include grouping symbols to separate both parts of the expression.
