15 = 80% * x
15 = 80/100 * x
15 = 8/10 * x
x = 15 * 10/8
x = 150/8
x = 18.75
<span>80% of 18.75 is </span>15<span>.</span>
So the three numbers can be turned into fractions.
1/5, 1/4, and 4/20.
fractions can be turned into decimals by dividing the denominator into the numerator.
now we have 0.2 , 0.25 , and 0.2
greatest to least, the numbers are 0.25 , 0.2 , and 0.2
(both 0.2s are equal, so order of those doesn't matter)
Answer:For the first one it would be x=35
And the 2nd one would just be x=-1
Step-by-step explanation:
You have 2x^2 + 9x -9 and 3x^2 -2x +14
To find total area add the two polynomials together by combining the like terms.
2x^2 + 3x^2 = 5x^2
9x + -2x = 9x-2x = 7x
-9 + 14 = 5
Total area = 5x^2 + 7x + 5
I think it’s A sorry if I’m wrong:)
