Answer: option A, 3x + 5
first, i rewrote it and removed the parentheses.
2x - 4 + x + 9
then, i collected the like terms.
3x + 5
Answer
x^154
54b^20
step by step
Answer:
5 > k
Step-by-step explanation:
-45 < -9k
Switch sides
-9k > -45
Multiply both sides by -1 (reverse the inequality)
( -9k )( -1 ) < ( -45 )( -1 )
Simplify
9k < 45
Divide both sides by 9
9k/9 < 45/9
Simplify
K < 5
(9x+5) - (6x-8) = 9x+5 - 6x+8 = (9x-6x) + (5+8) = 3x+13
___
(4x+10) - (-3x+5) = 4x+10 + 3x-5 = (4x+3x) + (10-5) = 7x+5
In order to add the fractions, we need to create complex fractions with a Least Common Denominator (LCD).
The LCD between 9 and 2 is 18
3 1/2 = 3(18/18) + 9/18 = 54/18 + 9/18 = 63/18
3/9 = 6/18
So now we can solve...
3 1/2 + 3/9 is the same as 63/18 + 6/18 = 69/18 = 3 5/6 which is none of the given answers.
