<span>64 boxes of pencils per case x 2.5 ounces per box ÷16 ounces per pound = pounds per case</span>
Answer:
D
Step-by-step explanation:
The other ones don't make sense. The answer is 3.5x+x=9.90
Perimeter of rectangle=66
length of rectangle=L
width of rectangle=w
P of a rect.= 2(length)+ 2(width)
66= 2L+2w
if the length is 7in more than the width, then
L=7+w
Now we will substitute 7+w in for L. Here is our new equation:
66=2(7+w) + 2w
Solve for w
66=14+2w+2w
66=14+4w
52=4w
w=13
L=7+13, so L=20
I hooe this is explained well enough
-10-f=-6f+10
-f+6f=10+10
5f=20
F=4
