<u>2/5 x + 1/3 x = 22</u>
First of all, I've been answering so many of these things lately that I'm
getting really tired of 'x'. Let's call the unknown number ' Q ' instead.
<u>2/5 Q + 1/3 Q = 22</u>
Multiply each side by 5 :
2Q + 5/3 Q = 110
Multiply each side by 3 :
6Q + 5Q = 330
Add the like terms on the left side:
11Q = 330
Divide each side by 11 :
<u>Q = 30</u> .

Answer:
b. -x^2 + 50 = 25
c. |2x| = 10
d. x < 0
e. 2x < 10
Step-by-step explanation:
x = -5
-(-5)² + 50
-25 + 50 = 25
|2(-5)| = |-10| = 10
-5 < 0
2(-5) = -10 < 10
