Subtract 32 to both sides to the equation becomes -5x^2 + 7x + 9 = 0.
To solve this equation, we can use the quadratic formula. The quadratic formula solves equations of the form ax^2 + bx + c = 0
x = [ -b ± √(b^2 - 4ac) ] / (2a)
x = [ -7 ± √(7^2 - 4(-5)(9)) ] / ( 2(-5) )
x = [ -7 ± √(49 - (-180) ) ] / ( -10 )
x = [ -7 ± √(229) ] / ( -10)
x = [ -7 ± sqrt(229) ] / ( -10 )
x = 7/10 ± -sqrt(229)/10
The answers are 7/10 + sqrt(229)/10 and 7/10 - sqrt(229)/10.
Answer:
A) 2/10 or 20%
B) 3/10 or 30%
Step-by-step explanation:
There are 10 ice pops.
10 is going to be your denominator
Your numerator is going to be whatever amount of ice pops is.
After finding your fraction, divide the numerator by the denominator.
Lastly turn your decimal into a fraction.
2/10=0.2=20%
Hope I helped you.
