The correct answer is cone.
There's only one face, and only one vertex that leads to a single base. There are no edges because the base perimeter is not considered to be an edge because it's a vertex.
2x-1=5
2(3)-1=5
6-1=5
5=5
x=3
27 over 40 (as a fraction)
WORK:
.675 is 675 over 1000
5 goes into both of those so
675/5=135 1000/5=200
135/5=27
200/5=40
There are 87 girls and 58 boys!
i divided 5 from 145 and got 29.
i multiplied 29 and 3 and got 87.
87 is the girls total.
then subtracted 87 from 145 and got 58.
58 is the boys total.
hope this helps!
