Since you know you have 16 erasers and 24 pencils, the first thing you should do is put it in to an actual ratio, like so:
16:24
Now that you have a ratio, you need to simplify it. It is very similar to simplifying fractions. You can start by dividing by 2, which gives you:
8:12
And by two again:
4:6
And again:
2:3
So you now know that Gregory’s ratio of erasers to pencils in his locker is 2:3!!
You could also divide 16:24 by 8 which gives you the answer quicker, but I find it easier to break it down in smaller, more manageable chunks. It’s all in finding a common multiple and making the ratio the smallest whole numbers possible :)
Answer:

Step-by-step explanation:
we know that
The volume of the square base pyramid is equal to
where
b is the length side of the square base
h is the height of the pyramid
we have
substitute the value of h
Find the volume
Answer:
Nothing
Step-by-step explanation:
<PRQ and <RQP are not the same angle, so we cannot apply the transitive property.
The equivalent expression is -12y + 48 or -12(y - 4) or 12(-y + 4)
<em><u>Solution:</u></em>
Given that we have to simplify to create an equivalent expression
<em><u>Given expression is:</u></em>
6(7 – 3y) + 6(y + 1)
Remove the parenthesis by multiplying terms inside the bracket with constant outside the bracket
Combine the like terms
Add the constants
Thus the equivalent expression is -12y + 48 or -12(y - 4) or 12(-y + 4)
