<u>Answer:</u>

<u>Explanation:</u>
let the number be x, now we are given that four times the cube of a number which means four multiplied by the cube of number
i.e 4 multiplied by
is less than the difference of 40 and the number x i.e 40 - x
x is for sure less than 40 as
is less than the difference between 40 and x so if we write x - 40 then we will obtain negative value which will be greater than
.
So, the inequality obtained can be written as 
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

The answer to your question is
No
Answer:
A.
Step-by-step explanation:
you have to find the discriminant
b²-4ac for each equation
if discriminant < 0 no real solutions because will be negative under the squareroot whhan you try to find the roots
if discriminant = 0 there is only one solution
if discriminant > 0 two real solutions
for your given problems
A. discriminant =(-2)²-4*2*15 will be negative
