BIDMAS
Step-by-step explanation:
FIRST DO 7+7÷7 AND TIMES THE ANSWER BY 7
We are asked to find 7 is what percent to 30.
We will use proportions to solve our given problem.
Let us assume that 7 is n% of 30. So we can set a proportion as:

Let us solve for n.




Therefore, 7 is
of 30.
If there are no repeating x values and an x value only goes to <em>one</em><em> </em>y value, then yes, it is a function.
A²-b²=(a-b)(a+b)
4x² - 25= (2x)²- 5² =(2x-5)(2x+5)
You do not have this choice, so the answer is D.None of the above.
Be right there! Let's do this!
