Step-by-step explanation:
Let 
, that is a be any real number.
The inverse property of addition says that, the sum of a number 
and its additive inverse 
gives the identity element of addition which is zero.
That is :
We can rewrite this as 
From the above options, we have the correct answer to be the first choice
3 3/22 isn't 69/66.
3 3/22 is like 3+3/22. To sum them,you have to have the same denominator. So 3=66/22. Know you can add them, so 3 3/22=3+ 3/22= 66/22+3/22=69/22.
Same way, 3 2/33= 3+2/33=99/33+2/33=101/33.
Know you have to compare 69/22 with 101/33. For this, you need to get them to the same denominator. So you multiply 69/22 with 3, and 101/33 with 2. Know you have to compare 207/66 with 202/66. Obviously, the first one is bigger, because 207>202. So in the end, 3 3/22> 3 2/33
A = 5
4a + b = 6
4(5) + b = 6
20 + b = 6
b = 6 - 20
b = - 14 <=== u can prove that b = -14
Answer:
x = -2
Step-by-step explanation:
-14 = x - 12
-14 + 12 = x
-2 = x
check:
-14 = -2 - 12
