Lois says any addition equation where the addends are all the same can be written as a multiplication equation. is lois correct? explain why or why not.

lois is correct. this is because multiplication is repeated addition. it means that when your addends are just the same number but added several times, the sum is just equivalent to the product of that number times the number of times it was added. for example, 4+4+4 = 4×3 = 12.

step-by-step explanation:

question 1 is 8, question 2 is 9, question 3 is 24

step-by-step explanation:

now, the numbers they give you at the top are the key. from there, you just have to plug and chug! let's try 1, 2, and 3!

key: a=3, b=5, c=6

1. a+5

remember, a=3, so we plug that in to get 3+5=8

2. 15-c

c=6, so we plug that in to get 15-6=9

3. 4b

b=6, so we plug it in to get 4*6=24

time to try the rest on your own! if you put the answers below in a comment, i'll check them for you!
