Whats -2(x-3)=5(2x+3)
puteri [66]
-2(x - 3) = 5(2x + 3)

-2x + 6 = 10x + 15

6 = 10x + 15 + 2

6 = 12x + 15

6 - 15 = 12x

-9 = 12x

-9/12 = x

-3/4 = x     or in decimal form; -0.75

hope this helps, God bless!

The bottom two questions that correspond to the word problem... I don't get it
lisov135 [29]
So basically, the first question after the word problem is asking you to write an equation to represent the value of Mama's car after a certain amount of years (t). Since the value of her car decreases by 3% each year, you could multiply 3% by the original value of her car, to find what 3% is, OR you could subtract 19,400 (the value of her car after 1 year) from 20,000 INSTEAD of multiplying 20,000 by 3%. 

Equation:  value=20,000 - 600t

To answer the next question, just plug it into the equation you created. 

500<20,000 - 600t

-19500< -600t

32.5>t
Final Answer: It would take at least 32 and 1/2 years for the value of Mama's car to be less than $500. 

Hope this helps!! :)
