Find how many numbers are divisible by two and three, then place that number above the total number of items in the set as a fraction. Like this:
Answer:
x=-6
Step-by-step explanation:
Let x be the number
3x = x^2 -54
Subtract 3x
3x-3x = x^2 -3x-54
0 = x^2 -3x-54
Factor
What 2 numbers multiply to -54 and add to -3
-9*6 = -54
-9+6 = -3
0=(x-9) (x+6)
Using the zero product property
x-9=0 x+6=0
x=9 x=-6
The questions asks for the negative solution
x=-6
1 dimes are worth 10 cents.
Multiply.
6 * 10 = 60
Put in a fraction with the denominator given.
60/100
Reduce the fraction.
60/100
30/50
15/25
3/5
Best of Luck!
