Answer:
-2x - 5 (lesser than or equal to) 15
You will have to form the equation:
1.01+.09x=9.56 Solve for x. Start buy subtracting 1.01 from both sides.
.09x=8.55 Divide both sides by .09
x=95 The call was 95 additional minutes. So...
25+95=120 120 minutes in total. Check your answer by substituting x...
1.01+.09(95)=9.56
1.01+8.55=9.56
9.56=9.56
I hope this helps!

Answer:
There are 600 students in this school.
Step-by-step explanation:
Let p represent the total population of the school.
Then (1/3)p represents the number of students who like math. Subtracting this (1/3)p from p gives an expression representing those who do not like math:
p - (1/3)p = (2/3)p
400 students do not like math, so (2/3)p = 400.
Solve this for p by multiplying both sides by (3/2):
(3/2)(2/3)p = (3/2)(400), which simplifies to p = 600.
There are 600 students in this school.
