You and your friend are selling your old CDs. Your friend sells 14 the first day, and x the next day. You sell y the first day a
Deffense [45]

Answer: 30+x+y

Step-by-step explanation:

  • Commutative Property of Addition : a+b= b+a , where a and b are any arbitrary numbers.

Given : Number of CDs sold by friend on first day = 14

Number of CDs sold by friend on next day = x

Total CDs sold by friend  = 14 +x

Number of CDs sold by you on first day = 16

Number of CDs sold by you on next day = y

Total CDs sold by you  = 16+y

The expression that shows the total number of CDs sold both days =

Total CDs sold by friend  + Total CDs sold by you

=  14 +x+ 16+y

= 14 +(x+ 16)+y

= 14 +(16+x)+y   [By Commutative Property of Addition.]

= 14+16+x+y

= 30+x+y

Hence, the expression that shows the total number of CDs sold both days :

30+x+y

A clear box has the shape of a rectangular prism and is filled with sand. Find the volume if the box
Strike441 [17]

Answer:

24 m³

Step-by-step explanation:

Since you didn't state the dimensions of the rectangular prism, and you didn't add a picture to show it's dimensions, then permit me to assume dimensions for the question

Assuming it's breadth is 2 m.

Assuming it's length is 4 m.

Assuming it's height is 3 m

Then the volume of a rectangular prism is given as l * b * h. Which means we multiply all the sides by one another. From my assumption of values, we have that 2 * 3 * 4, and this gives us 24 m³

24 m

Now what you'd do is substitute your values for my assumed values.. Cheers

Solve the following 32 divided by 4 + 4 x 8
gizmo_the_mogwai [7]
You need to use pemdas here to understand order of operations. So you need to multiply the 8 by the 4 to give 32, then add 4 to get 36. And now you can take the 32 and divide. So you get 36/32 or 9/8
