Answer:
3
Step-by-step explanation:
3x+3-x+3=12
3x-x=12-3-3
2x=6
x=6/2
x=3
Answer:
x=3/2y+3
Step-by-step explanation:
Let's solve for x.
2x−3y=6
Step 1: Add 3y to both sides.
2x−3y+3y=6+3y
2x=3y+6
Step 2: Divide both sides by 2.
2x2=3y+62
x=32y+3
You take out the biggest factor of 9 and 36 which is 9c^2. The factors both have the c variable in common so you take the least exponent and put it with the gcf.
9c^2(c^2+4)
Consider that 100%-72%=28% represents the percentage of wrong answers. I would think as fractions as:
if 100% is the total number of answers and 28% are the wrong ones
as
if x is the total you have 14 wrong you can write:

x=(100/28)*14=50 questions
Answer:
30 degrees
Step-by-step explanation:
USE the sine function to determine S. Set up the equation:
sine(S) = 1/2 -->
S = Sine^-1(1/2) -->
S = 30 degrees
