Question

Cassie has 8 red marbles and 12 yellow marbles. Her mom doubles her red and yellow marbles for her birthday. Use the distributive property to show how many marbles Cassie has.

Answer 1

Answer:

Cassie will have 40 marbles.

Step-by-step explanation:

Cassie has 8 red marbles and 12 yellow marbles.

Her mom doubles her red and yellow marbles for her birthday.

So, we can denote this mathematically as:

2(8) for red marbles.

2(12) for yellow marbles.

We can write total marbles as:

$2(8)+2(12)$ or

$(8+12)\times2$

= $(20)\times2$

Total marbles = 40

Answer 2

2(8+12)

Distribute the 2 to the 8 and the 12

16+24

40
