Answer:
Step-by-step explanation:
Make a quadratic:
2
-8x+7=0
Then use quadratic formula to solve.
It would be x= 2 ± 
14(3+1) - (3 - 7)
"double" - times by 2
"and" - addition
when using " first second and third" you just have to assign the numbers by the way it comes in the problem...
first number - 7
second number - 3
third number - 1
Answer:
15:100:60 or simplify to 3:20:12
Step-by-step explanation:
15 is 15 percent of 100, 60 is 3/5 of 100. assume x is 100 because it makes the answer simpler. finally simplify by dividing everything by 5 so that you get the most simplified version of the equation because 3 is a pride umber and can no longer be divided unless in fraction or decimal form.
