Hope this helps!
What you need to do is to find a multiple of 20 and 16 in other words a number that can multiply into 20 and 16. You have 2 and you have 4. So now this is how it looks like.
Either:
4(5+4) Or
2(10+8)
A triangles angles add up to 180 degrees so
88 + 77 + 8 has to equal 88 or the triangle is impossible and
88 + 77 + 8 = 173
so the triangle would be impossible.
Answer:
$50
Step-by-step explanation:
Create a proportion where x is the cost of 8 books:
=
Cross multiply and solve for x:
3x = 150
x = 50
So, 8 books would cost $50
