Answer:

s < 8

Step-by-step explanation:

7−s/2>3

Subtract 7 from each side

7-7−s/2>3-7

-s/2 > -4

Multiply each side by -2. Remember to flip the inequality since we are multiplying by a negative.

-s/2 * -2 < -4*-2

s < 8

professor190 [17]

Answer:

For c=5 there are not solutions for the compound inequality

Step-by-step explanation:

we know that

In the compound inequality

$x < 5$ -----> inequality A

$x > c$ -----> inequality B

The solution of the system of inequalities must satisfy inequality A and must satisfy inequality B

If c=5

then

There is no solution that satisfies both inequalities simultaneously.

therefore

For c=5 there are not solutions for the compound inequality

The school that Lisa goes to is selling tickets to the annual talent show. On the first day of ticket sales the school sold 4 se

kakasveta [241]

Let:
x = cost of senior citizen ticket
y = cost of student ticket

4x + 5y = 102
7x + 5y = 126

4x + 5y = 102
4x = 102 - 5y
x = (102 - 5y)/4
x = 102/4 - 5y/4

7x + 5y = 126
7(102/4 - 5y/4) + 5y = 126
(714/4 - 35y/4) + 5y = 126
-35y/4 + 5y = 126 - 714/4

note:
-35y/4 = -8.75y
714/4 = 178.5

-8.75y + 5y = 126 - 178.5
-3.75y = -52.5
y = -52.5/-3.75
y = 14

x = 102/4 - 5y/4
x = 102/4 - 5(14)/4
x = 8

x = cost of senior citizen ticket = $8/ea
y = cost of student ticket = $14/ea
