The machine could punch out 500 plastic pterodactyls in 20 minutes at that rate how many could it punch out in 1 and 1/2 hours

1 answer:

8 0

I would find it easiest to reduce the number to minutes, like this: 500 in 20 minutes would be 500 divided by 20 = 25 pteradactyls /min.

There are 90 minutes in an hour and a half, so 25 x 90 = 2,250 pteradactyls in 1 1/2 hours.

Please help with Part A and Part B

svp [43]

Part A:
The area of the rectangle will be the length times the width, so 4•(x+3). Using distributive property, you'll multiply every term inside the parentheses by 4.

The area of the rectangle can be expressed by 4x+12.

Part B:
Multiply 4•2 and (x+3)•2, then multiply them together.

8(2x+6) Now use distributive property to find your answer simplified.

16x+48 is your answer
