Idon’t understand number 18 i wrote the equation but i need solving it the equation is 13 n - 1.50= 35.50

Hi there!

It appears you've written the equation wrong.

It should be: 13 + 1.5n ≤ 35.5

(13 - 13) + 1.5n ≤ (35.5 - 13)

1.5n ≤ 22.5

1.5n / 1.5 ≤ 22.5 / 1.5

n ≤ 15 rides

The most amount of rides you can take is 15.

Hope this helps.

1. 8 or -82. 14 or -143. -11, -3, 0, 7, 10

The 8th term is 512
