If a rug is 6 feet wide by 8 feet long and suki makes a diagram that is 1 1/3 feet long how many inches should its width be
soldier1979 [14.2K]
The length in the diagram is 4/3 feet.
(4/3)/8=w/6 where w is the width.
So 4/(3×8)=w/6.
1/6=w/6 so w=1 foot or 12 inches.

3.<br>What is the<br>distributive property<br>of<br>40 + 64?​
Ivan

Answer:

104

Step-by-step explanation:

This is not a distributive property question though.

A distributive property has a number (a) outside the parenthesis

a(b+c)

so in this case a(40+64)

then you would multiply a by both numbers

40a+64a

then add them together

104a

However if it is a number outside the parenthesis and not a variable, it will come out different

For example

5(40+64)

(5*40)+(5*64)

200+320

520

Hope this helps!
