wlad13 [49]

Answer:

6 combinations

Step-by-step explanation:

Let

x----> the number of adult tickets

y---> the number of a child tickets

we know that

5x+3y=100 ----> linear equation that represent the situation

y=-(5/3)x+(100/3)

The maximum number of adult tickets is 20 (20*$5=$100)

The maximum number of a child tickets is 33 (33*$3=$99)

Construct a table for different values of x and find the values of y

The possible combinations will be pairs of whole numbers

see the attached table

The solution is 6 combinations

Select all the equations that are equivalent. 52 = 8n + 4 4(2n + 1) = 52 4 = 52 – 8n 4n = 48 n = 6

san4es73 [151]

Answer:

52 = 8n + 4

4(2n + 1) = 52

4 = 52 – 8n

n = 6

Step-by-step explanation:

52 = 8n + 4

52 - 4 = 8n

48 = 8n

n = 48/8

n = 6

4(2n + 1) = 52

8n + 4 = 52

8n = 52 - 4

8n = 48

n = 48/8

n = 6

4 = 52 – 8n

4 - 52 = -8n

-48 = -8n

n = -48/-8

n = 6

4n = 48

n = 48/4

n =12

n = 6

52 = 8n + 4 is equivalent to 4(2n + 1) = 52 is equivalent to 4 = 52 – 8n is equivalent to n = 6
