Answer: The things that we know in this problem are:

"the number of postcards is 12 more than 3/4 of the number of stamps"

This means that if P is the number of postcards, and S the number of stamps, then:

P - (3/4)S = 12

And we also know that P = 39

39 - (3/4)S = 12

(3/4)S =39 - 12 = 27

S = (4/3)*27 = 36

So he has 36 stamps.

then the correct answer is A.

The area of a rectangular garden is 38 1/4 square meters the width of the garden is 4 1/2 meters what is the length of the garde
Snowcat [4.5K]

Hello...

Area is measured by the formula A=L*W (Area = Length X Width)  We know the area is 38 1/4 and the width is 4 1/2. It is easiest to convert them to decimals and solve. 38 1/4 = 38.25 and 4 1/2= 4.5 .    so, 38.25 = 4.5 * W

To solve for Width, we need to isolate it by getting 4.5 on the other side. To do this, we divide by 4.5 on both sides of the equals sign. this will give us W=8.5 or Width = 8 1/2 meters.
