The property used in step 6 is the additive inverse.
<h3>What are algebra properties?</h3>
Algebra properties are mathematical properties used to simplify algebraic expressions
In step 6, we have the following expression:
The additive property of algebra states that:
i.e. when a number or an expression is added to its inverse, the result is 0.
In , we have:
2 and -2
2 and -2 are inverses or opposites.
So, when they are added; the result is 0
Hence, the property used in step 6 is the additive inverse.

Answer:
-9y-2(2-7y)+4 expand the brackets using-2
Step-by-step explanation:
-9y-4+14y+4
arrange the like terms
-9y+14y-4+4
=5y becoz -4+4=0
ans=5y
Answer: $2.40
Step-by-step explanation:
If Kevin gets 12 dollars for every 5 problems, we will need to divide 12 by 5 to find the unit rate; how much Kevin gets for each problem.
12 ÷ 5 = 2.4, and in dollars it is equal to $2.40. Because of this, Kevin is paid $2.40 for each problem he makes for the ST2 publishing Company.
Answer:
2
Step-by-step explanation:
So let's call the time she needs to catch up "x", and so Terry's rate would be x-6 since he left home 6 hours earlier. Then we multiply the rates to get 20x - 120 = 80x. The answer is -2, but we can just say 2.
Checking our answer, that means if it took Sally 2 hours, it took Terry 8 hours for he left home 6 hours earlier. So 8 times 20 = 160km traveled. 2 times 80 = 160km traveled. Same distance.
Answer:
Ah! Geometric sequences, Eh? Sucks I know....
Step-by-step explanation:
So first, we need to find the factor of this(been a while since I have done this)
So we found the relationship! Now we find the entire equation.
So we know the first term, 96, so let's use it!
So there is the equation!
Now to find the 10th term.
There you have it!
Hope this Helps!
P.S. Stay Safe!
