Since the total measure of all the angles of a triangle is always 180, solve for x with the equation: 3x+1+2x-3+9x=180. x=13. Now plug in x and look for the smallest one, which will be B. 23 degrees.
Answer:
Step-by-step explanation:
To solve this you take 0 as the starting number, he lost 20 points so you subtract 20 and get -20. Next add 15 points. You then get -5. Then he got another answer right so you add 35 to -5. It the same if you say 35-5. Which gives you 30. So your answer is 30
Answer:
8x + 5
Step-by-step explanation:
5 * (2x+1) = 10x +5
10x + 5 -2x
8x + 5
X - the number
4x² - four times its square
if you subtract the number from four times its square:
4x²-x
the result is three:
4x²-x=3
