Boys : Girls : Total
33 : 11 : 44
Find the simplest form:
3 : 1 : 4
Set the total to 60 ( so we multiply by 15)
3 x 15 : 1 x 15 : 4 x 15
45 : 15 : 60
Boys = 45
Girls = 15
Total = 60
Ans: There are 15 girls that signed up

Answer:
-7/2 = -2(x-1/2)^2
Step-by-step explanation:
0 = –2x^2 + 2x + 3
Subtract 3 from each side
-3 = –2x^2 + 2x
Factor out the -2
-3 =- 2(x^2 -x)
Take the coefficient of x and divide by 2 and square it
-1 /2 = -1/2 ^2 = 1/4
Add it to each side Remember the -2 on the outside so we need to multiply it by -2
-2 *1/4 = -1/2
-3 -1/2= -2(x^2 -x +1/4)
-7/2 = -2(x^2 -x +1/4)
-7/2 = -2(x-1/2)^2
