2x^2=50
/2. /2
X^2=25
To get x alone you have to square root the ^2 to cancel it out , and what you do to one side you must do to the other. This means you also have to square root 25
The square root of x^2 is x and the square root of 25 is 5
The answer is x=5
Five Millon four thousand and three hundred
Answer:
2y - 15
Step-by-step explanation:
well 15 LESS than TWICE a number. okay so let’s start off by making a variable for the unknown number.... y. the variable is y. so now we have to think, TWICE that number, but we don’t know the number.
Now that we have the variable and we know it has to be doubled, let’s start off making the first half... we can out that into 2y. which is 2 multiplied by the unknown number.
now that we have the first half done, we have to take the 15 less. Less can mean or subtract in this kind of situation. but for this certain scenario, it will be subtraction. so the equation would be 2y - 15.
