Answer:

There are 25 students in the class.

Step-by-step explanation:

Since we know the percentage of students who want an ice cream party is 20%, and 5 students want an ice cream party, we know that:

$\frac{5}{S}=0.2$

, where S is the total amount of students. We can then solve for S:

$\frac{5}{S}=0.2$ Given equation

$5=0.2*S$ Multiply by S

$25=S$ Divide by 0.2

Therefore, there are 25 students in the class.

Solve this quadratic equation using the quadratic formula. 5 - 10x - 3x2 = 0

horsena [70]

Answer:

x = (-5 ± 2√10) / 3

Step-by-step explanation:

5 − 10x − 3x² = 0

Write in standard form:

-3x² − 10x + 5 = 0

Solve with quadratic formula:

x = [ -b ± √(b² − 4ac) ] / 2a

x = [ -(-10) ± √((-10)² − 4(-3)(5)) ] / 2(-3)

x = [ 10 ± √(100 + 60) ] / -6

x = (10 ± 4√10) / -6

x = (-5 ± 2√10) / 3
