All you are really doing is if you divide you are moving the decimal to the left and when you times you are moving the decimal to the right
Answer: divison is were you divided numbers and multiplication is were you times the number
Step-by-step explanation:
L = length w = width
Write System of Equations:
l = 2w
l + w = 66
Substitute 2w for l:
2w + w = 66
3w = 66
w = 22
Solve for l:
l = 2w
l = 2(22)
l = ww
Answer:
$90-$70=$20
Step-by-step explanation: U take 90 from 20
Answer:

Step-by-step explanation:
We can divide it into two parts:
First, we can fin the volume of the parallelepiped:
h1 = 16 cm
w1 = 2 cm
d1 = 3 cm

Now, the volume of the second parallelepiped is:
h2 = (8-2) cm = 6 cm
w2 = 2 cm
d2 = 3 cm

Finally, the total volume will be the addition of these two volumes.

I hope it helps you!
