Answer 2
Answer:

The Associative Property of Mulitplication states that you can solve the expression by switching the group order. Since the current group is (7*50), we can change the group to (50*4).

From this: (7*50)*4

To This: 7*(50*4)

Hope this helps! Please correct me if I have made any mistakes!

At the market 2.4 pounds of peas cost 1.68 how much does one pound of peas cost?

Answers

it think the answer would probably be 4.08
2.4x=1.68. x= 1pound
So to get the x away from the 2.4 you must divide. And what you do to one side of the equation you must do to the other side
2.4/2.4=1 So then you would go 1.68/2.4 to calculate the cost of one pound

The dimensions of rectangular prism X are twice the dimensions of rectangular prism Y. The surface area of prism X is 100 square inches. What is the surface area of prism Y? The dimensions of Prism Z are three times the dimensions of rectangular prism Y. What is the surface area of prism Z?PLEASEEE help and it would be awesome to tell me how you got your answer so I know what to do.
Thx!

Answers

Given: 
Dimensions of rectangular prism X are twice the dimension of rectangular prism Y.

prism X = 2(prism Y)
Surface area of X = 2(Surface area of Y)
100 square inches = 2(Surface area of Y)
100 square inches ÷ 2 = Surface area of Y
50 square inches = Surface area of Y

Dimensions of Prism Z are three times the dimensions of rectangular prism Y.

Prism Z = 3(Prism Y)
Surface Area Z = 3(50 square inches)
Surface Area of Z = 150 square inches
