X + 25 - 10. 25-10 is 15 so you had 15 after class. You must had 8 sheets of paper because 8+25=33. 33-15 is 18. So, you had 8 sheets of paper before class. Hope this helps!
Subtract 3 from each side to isolate the x and you get x=y-3
Answer:
scalene triangle
Not a right angled triangle cause 2,10,11 are not Pythagorean triplets.
Using the identity:
, we get:
There are two solutions to this equation:
1) Since the period of cosine is 2π, so 0 + 2π = 2π will also be a solution to the given equation
2) Therefore, there are 3 solutions to the given trigonometric equation.
so we're trying to figure what portion of silas' slime is detergent. we know that his slime is a combo of 5 oz glue and 2 oz detergent for a total of 7 oz of slime.
what we want to find is how much of those 7 oz of slime is detergent.
quite simply 2 oz of the 7 is detergent.
to make that into a percent just divide 2 by 7.
2/7 = 0.2857
then move the decimal over two spots to get
28.57 or
D. 28.6%
just remember that percents are just how much makes up the whole.
