For this case what we have to take into account is the following variable:
x = represent the unknown number
We now write the following inequality:
"four times the sum of number and 15 is at least 20"
4 (x + 15)> = 20
We clear the value of x:
(x + 15)> = 20/4
(x + 15)> = 5
x> = 5 - 15
x> = - 10
The solution set is:
[-10, inf)
Answer:
all possible values for X are:
[-10, inf)

i think probably 20
Step-by-step explanation:
if 200 students, students do not prefer math 10/100 × 200 = 20
Step-by-step explanation:
2-×^2
t(×)=3×
(s o t )(x)=st(×)=s(t(x))=2-(3×)^2=2-9x^2
(s o t)(-7) =2-9(-7)^2=2-9(49)= 2-441= -439
Answer:
do no
