Which expression is equivalent to x + 11? 11 x 11 + x 11 minus x Negative x + 11

11 + x

Step-by-step explanation:

Let's write out each of the answer choices:

A) 11x

B) 11 + x

C) 11 minus x  ⇒  11 - x

D) Negative x + 11  ⇒  -x + 11

Examine each of them. Clearly, A and D aren't the same (A is multiplication, not addition, and D has a negative x instead of a positive x). C is actually the same as D, if you switch the places of 11 and -x: 11 - x = -x = 11.

Finally, answer choice B is correct because by the Commutative Property of Addition, 11 + x = x + 11.

Hope this helps!

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!
