Answer:
A) , C)
Step-by-step explanation:
Additive inverse means that, when the pair of integers are added together, they will equal 0. In this case, your answers are:
a. 4, -4
4 + (-4) = 4 - 4 = 0
c. 5, -5
5 + (-5) = 5 - 5 = 0
A) & C) is your answer. Note that you must have the same number, in which one is positive, and the other negative.

Answer:
$2500
Step-by-step explanation:
25% is one fourth of the total monthly income.
If $625 is = x/4 then multiply both sides of the equation with 4
4 × 625 = x/4 × 4 ➡ 2500 = x
You know this when the two values (x and y) are inversely proportional to each other by their product being constant (always remaining the same). This means when x increases y will decrease.
Hope this helped :)

12.6
Step-by-step explanation:
1.8X7
7x1=7
0.8x7=5.6
7+5.6=12.6
Answer:
B) 36/(y+4)
Step-by-step explanation:
Use the process of elimination.
A cannot work because we are changing the operation. Instead of dividing thirty-six by the sum of four and a number, we are dividing thirty-six by four, then adding the unknown number. This is not the same as the original expression, so we know it is not this.
Next, check C. C doesn't seem right either. Remember that, unlike multiplication and addition, you cannot flip the order in which the operation is being done and still get the same answer. C says four plus a number divided by thirty-six, which is entirely different from our original expression. So the answer is not C.
And finally, check D. D doesn't work either. With D, we are dividing thirty-six by a number, then adding it to thirty-six divided by four. This is not the same as our original expression, so D isn't it.
That leaves us with B. Does it work? Yes, because changing the y and the four still will give the same thing. And yes, because 36 is being divided by the sum of that number and four. So it is our answer.
