Answer:
9
Step-by-step explanation:
Simplifying
2y + -6 = 12
Reorder the terms:
-6 + 2y = 12
Solving
-6 + 2y = 12
Solving for variable 'y'.
Move all terms containing y to the left, all other terms to the right.
Add '6' to each side of the equation.
-6 + 6 + 2y = 12 + 6
Combine like terms: -6 + 6 = 0
0 + 2y = 12 + 6
2y = 12 + 6
Combine like terms: 12 + 6 = 18
2y = 18
Divide each side by '2'.
y = 9
Simplifying
y = 9
Let
x---------> my favorite number
we know that
(x+9)/15=3/5------> 5*(x+9)=15*3-----> divide by 5 both sides----> (x+9)=3*3
x+9=9------> x=0
therefore
the answer is
My favorite number is 0

Two conditionals from each biconditional are
- (1) A month has exactly 28 days (2) It is February
- (1)Two angels are complementary (2) The measures of the angles add up to 90
- (1) The area of square s^2 (2) The perimeter of the square is 4s
<h3>How to write two conditionals from each biconditional?</h3>
A biconditional statement is represented as:
if and only if p, then q
From the above biconditional statement, we have the following conditional statements
Conditional statement 1: p
Conditional statement 2: q
Using the above as a guide, the conditional statements from the biconditional statements are:
<u>Biconditional statement 30</u>
- A month has exactly 28 days
- It is February
<u>Biconditional statement 31</u>
- Two angels are complementary
- The measures of the angles add up to 90
<u>Biconditional statement 32</u>
- The area of square s^2
- The perimeter of the square is 4s
