Answer:
The percent of boys and girls that naden it to the honor roll increased by 27 percent (27%)
Step-by-step explanation:
2x+4=sqrt(64)
x=8-4/2
x=-8-4/2
x=2 and x = -6
If you're doing it mentally, you should find a common factor between the nominator and denominator that also multiplies to make 100.

That gives you: 3/4
3/4 is 75%
3 x 25 = 75
