Answer:
x >
Step-by-step explanation:
Given
x - > 1
Multiply through by 15 to clear the fractions
10x - 3 > 15 ( add 3 to both sides )
10x > 18 ( divide both sides by 10 )
x > , that is
x >

Answer:
Step-by-step explanation:
let the national average be x
11/100 * x = 11x/100
25.47 - x = 11x/100
100(25.47-x) = 11x
2547 - 100x = 11x
2547 = 11x + 100x
2547 = 111x
x = 2547/111
x = 22.945945945946
22.95
Answer:
Step-by-step explanation:
Let x represent the number of adult tickets that were sold.
Let y represent the number of children tickets that were sold.
The auditorium can hold no more than 200 audience members. This means that
x + y ≤ 200
An adult ticket costs $9 and a child's ticket costs $4. The students would like ticket sales of at least $1300. This means that
9x + 4y ≥ 1300
These are the set of inequalities that represents the situation.
