If anyone can figure the answer, please tell me. Anything would be helpful :) I have to master 20 lessons for khan all 100% and it's very difficult for some of them.

Adeli charges the same price, $5.50, for all of its different sandwiches. if a company ordered n sandwiches for a luncheon, which equation could be used to find the total price, p, that the deli charged for the sandwiches? a- n/5.50=p b-5.50n=p c-5.50/n=p d-5.50+n=p

What is the answer to this question? i'm a bit stumped. also how do i do it? 5(x - 4) = 2(x + 5)

Could someone with number 1 and 2
