Answer:
Below
Step-by-step explanation:
Let's prove that cos^2(O) = 1+ cos(2O)/2
We khow that cos(2O) = 2 cos^2-1
● cos(2O) = 2 cos^2-1
Add one to both sides:
● cos(2O) +1 = 2 cos^2-1+1
● cos(2O) +1 = 2 cos ^2
Divide both sides by 2
● [cos(2O)+1]/2 = cos^2
When you multiply two fractions together, multiply the two top numbers and then multiply the two bottom numbers.
5/12 x 1/3 = (5x1) / (12x3) = 5/36
For this case we have:
Let p be the highest price of the TV that Meg can buy
We have to:
5% of p is given by:
So, we have:
Clearing p we have:
Thus, the highest price of the television that Meg purchases should be 
dollars.
Answer:
Answer:
the first one
Step-by-step explanation:
The first equation is -5m+15
and the first one is 15-5m
Which is basically the same thing.

First, lets figure out how many pencils we will need. so we can do that by 4 pencils x 28 children and we get 112. Then if there are 8 pencils in a package, we divide 112 by 8 and get 14
