Five times a number added to negative 8, subtracted from triple the sum of eight times the number and 3

How do i put this in a mathematical expression?

Let the u known number = x

Five times the number added to negative eight would be written as:

5x + (-8) which simplifies tips 5x -8

That gets subtracted from triple the sum of eight times the number and 3. Sum is addition so that part of the equation would be 3(8x+3)

Final equation is : 3(8x+3) - 5x -8

This can then be simplified to :

3(8x+3) = 24x +9

To get: 24x +9 -5x-8

Combine like terms to get: 19x+1

step-by-step explanation:

answer: - (a)

(b) 88 seats

step-by-step explanation:

given: in an auditorium, there are 22 seats in the first row and 28 seats in the second row.

thus first term=

second term=

the number of seats in a row continues to increase by 6 with each additional row.

⇒d= 6

a) given formula :

b)   let the number of seats (n) = 12

substitute n=12 in the explicit rule formed in (a)

∴there are 88 seats in 12 rows.
