Question

Can you please help ?

Answer 1

69

Explanation:

The order of operations is PEMDAS; parentheses, exponents, multiplication and division, and finally addition and subtraction.

We know that x is the first row, and if there are 30 spots in the first row, then x=30. Using this information, all we have to do now is plug in 30 for x and solve.

`(5(x))/(2) -6`

`(5(30))/(2)-6`

`(150)/(2)-6`

`75-6`

`69`
