Answer:

commercial =  9

movie = 5

Step-by-step explanation:

Step one:

let the number of commercials be x and movies be y

so

40x+130y=1010-------------1

since there are a total of 14 commercials and movies combined

x+y=14--------------2

Hence the systems of equation is

40x+130y=1010------1

x+y=14-------------------2

Step two:

from equation 2

x=14-y

substui]te the value of x in  equation 1

40(14-y)+130y=1010

560-40y+130y=1010

collect like terms

130y-40y=1010-560

90y=450

divide both sides by 90

y=450/90

y=5

movies is 90

put y=5 in equation 2

x+5=14

x=14-5

x= 9

commercial is 9 in numbers

and movie is 5

Answer:

Ln or an = 3n - 16

Step-by-step explanation:

This is an arithmetic series. You are adding 4 to get the next term.

Ln = a + (n - 1)d

Ln is the last term or the nth term.

a = - 13

d = 3

Solution

Ln = - 13 + (n - 1)3          Remove the brackets

Ln = - 13 + 3n - 3           Combine like terms

Ln = -16 + 3n or

Ln = 3n - 16
