I really don’t know sorry I’m doing it for the points
Let x=the number of $1 bills she has, and let y=the number of $5 she has. From the information given, we can say:
x+5y=40
x+y=12
When you subtract the first equation from the second equation, you get:
x+5y-x-y=40-12
4y=28
y=7
Therefore, Hermione has 7 $5 bills in her purse.
{ Answer(s) }
Left side of big triangle (X & Y) : 15
Bottom side of big triangle (Y & Z) : 20
{ Explanation }
We know the top sides of both triangles. To find out how many units they are separated by, we need to divide 5 by 25.
25 / 5 = 5
Now we can continue.
3 * 5 = 15
4 * 5 = 20
The missing sides are 15 and 20.
