First, we translate the information that the question gives us:20+x is "twenty added to a certain number"(20+x)/5 is "the sum divided by five"1+12x is "one more than twelve times the original number"Putting it all together, we get the following equation:(x+20)/5 = 1 + 12xSolve for x:x+20=5(1+12x)x+20=5+60x20-5=60x-x15=59x15/59 = xTherefore, the original number was 15/59
The constant is 3.
This is because when x=1, y=3 and when x=2, y=6 so that is a constant change over each interval as seen in the graph which is 3 :)
126+24x=90+30x
x = the number of hours
then you solve the equation
The answer is x=6, so after 6 hours they will be on the same page.

Answer: 7 cars
Step-by-step explanation: Since he earned 400$ a week and he had 1450$ by the end, subtract 1450-400 and you get 1050. You then divide 1050 by 150 (1050÷150) and you get 7, so he sold 7 cars
