The answer is 52 hopefully this help
A) The with is 8 inches. You would do 32/4 to get your answer
B) The perimeter is 12. P=l+w so P=8+4 which is 12.(P stands for perimeter
36÷4. 4 goes into 36, 9 times. Do your check work, which would be 9x4=36√. Hope that helps!
Write it out as a set of equation:
Let x be number of 8 cent stamps, y be 10 cent stamps, and z be 2 cent stamps.
x=y
z=x+y
8x+10y+2z=440
Lets first solve for x:
from x=y and z=2x(from first equation) the last equation is
8x+10x+4x=440
22x=440
x=20
know that x=20, you also know that y=20 as well, since z=x+y, z=40.
So 20 8-cent stamps, 20 10-cent stamps, and 40 2-cent stamps.
