Answer:a=4
Step-by-step explanation:
Simplifying
4a + -5 + 2a + 9 = 28
Reorder the terms:
-5 + 9 + 4a + 2a = 28
Combine like terms: -5 + 9 = 4
4 + 4a + 2a = 28
Combine like terms: 4a + 2a = 6a
4 + 6a = 28
Solving
4 + 6a = 28
Solving for variable 'a'.
Move all terms containing a to the left, all other terms to the right.
Add '-4' to each side of the equation.
4 + -4 + 6a = 28 + -4
Combine like terms: 4 + -4 = 0
0 + 6a = 28 + -4
6a = 28 + -4
Combine like terms: 28 + -4 = 24
6a = 24
Divide each side by '6'.
a = 4
Simplifying
a = 4
Woah I haven’t done this in a while but all sides have to add up to 180 and the top angle is 60 because it’s a 30, 60, 90 triangel.
Start at 0,0 and go up on over 4 and keep going and do it both ways
until you run out of room
3-|4-n|>1
3-3 -|4-n| > 1-3
-|4-n| > -2
-|4-n|/-1 > -2/-1
|4-n| < 2
**inequality flips when dividing by a negative, absolute values give 2 answers
4-n <2
or
4-n >-2
n > 2. or. n < 6
2 < n < 6
