Hey there!
a + 2 = 10
SUBTRACT 2 to BOTH SIDES
a + 2 - 2 = 10 - 2
CANCEL out: 2 - 2 because that gives you 0
KEEP: 10 - 2 because that helps solve for the a-value
10 - 2 = a
10 - 2 = 8
Answer: Option C. a = 8
Good luck on your assignment and enjoy your day!

Answer:
closest answer = 81
Step-by-step explanation:
81/27 = 3
81/30= 2.7
81/45 = 1.8
The first step of simplifying the expression would be summing up the "i"s. They are separate ("+i" and "+5i") but you can still sum them up though they are apart. This is thanks to the commutative property of addition which allows summing the terms of an expression with several additions in whatever order it is prefered. Commutative means that the terms can be interchangeable.
Answer:
- x > -2
- n ≤ -2 or n ≥ 8
Step-by-step explanation:
<h3>1.</h3>
Add 7x-2 to both sides and collect terms.
2x +2 -6x +7x -2 > -4 -7x +7x -2
3x > -6
x > -2 . . . . . . . divide by 3
