A. n = 36
B. n = 18
C. n = 3
D. n = 4
Translate the following sentence into an equation. Then solve the equation.
3. The difference of a number and 7 is 21.
A. 21-7=n; n=14
B. n + 7=21; n=14
C. n-7=21; n=28
D. 21-n=7;n =14
4. Suppose you bought a pizza for $8.00. You also bought a salad, but you cannot remember how much you paid and you cannot find a receipt. You know that the total cost you spent was $10.00. Which equation would be best to use to find the cost of the salad
A. 8 + s = 10
B. 8 + 10 = s
C. 8 x s = 10
D. 10 x s =$8
5. How many more books do you need to read over the summer if you already read 4 books and you need to read a total of 16 books? Write a equation to represent this situation and solve the equation using mental math.

B. 4 x b = 16; b = 4 more books
C. 4 +16 = b; b = 20 more books
D. 4 + b = 16; b = 12 more books
Yeah, thx, but I think you forgot to put in the answer to number 2, or you just didn't know. I'm not hating, sorry. But, the answers are:
1. B
2. C

I promise, these answers are 100%, I just took the test/quick check if you are a Connexus student ;D
Thx Tempest!!!!!!!! i got a 100%!!!!!!!!!!
That answer is wrong I forgot to check. Thanks to my friend, the answer seems to be n=14
1. n + 7 = 21.
n = 14.
3. n - 7 = 21.
n =
4. 8 + s = 10.
5. 4 + b = 16.
I know alot of people put there 100% answers but i want to too.
B
C
C
A
D
Hope this helps. P.S. I am not in Connexus but it should work still.
Tempest is correct and i iz succeful xD
