<span>Which statement about the following equation is true?

3x^2-8x+5=5x^2

[8/(2x-2)=(8+6)/(3x)
 8/(2x-2)=14/(3x)
 14(2x-2)=8(3x)
 28x-28=24x
x=7
So by using the similarity of the sides, we can make ratios that can give is the value of x.<span />

The table shows the Grades that students received on a test what fraction of the students scored an A or B on the test
Triss [41]
Okay. So, 15% is 15/100 and 33% is 33/100. 15 + 33 is 48. You leave the denominator the same, so the fraction is 48/100. However, the fraction needs to be simplified. Whatever you do to the numerator, we must do to the denominator. We can divide both numbers by 4 to get the simplified fraction form. 48/4 is 12. 100/4 is 25. There. The simplified fraction is 12/25. The answer is H: 12/25.

a circus charges $2.50 for kids tickets and $6 for adult tickets last week and twice as many kids attended the circus than adult
aliina [53]
Let
x-----------> the number of kids
y----------> the number of adults

we know that
2.5x+6y=$7150---------> equation 1
x=2y-------------> equation 2
substitute 2 in 1
2.5*[2y]+6y=7150-----> 5y+6y=7150----> 11y=7150-----> y=650
x=2y----> x=2*650----> 1300

the answer is
the number of kids is 1300
