1 = 90
2 = 65
3 = 65
4 = 25
90+25=115
180-115=65
have a merry christmas :)
Let x be the number of 5 points question.
Let y be the number of 2 points question.
Total number of questions is 38
x + y = 38
Total points is 100
5x + 2y = 100
x + y = 38 ------------- (1)
5x + 2y = 100 ---------(2)
From (1):
x + y = 38
x = 38 - y -------------- sub into (2)
5(38 - y) + 2y = 100
190 - 5y + 2y = 100
3y = 90
y = 30 ------------------ sub into (1)
x + 30 = 38
x = 38 - 30
x = 8
There are 8 5-point questions and 30 2-point questions
Well If john has to pay
89.95 a month so 179.9$
He was given 95$ from the company so 179.9 - 95= 84.9
and he owes 12.75 for late fees so 84.9 + 12.75
He owes a grand total of 97.4$ to the phone company
1. 60 because 5 x 12 = 60
2. 84 is the next one because 14 x 6 = 84
(if number two is wrong forgive me)
there are 6 sections and the sections are 4 x 4
so the correct expression can be 6x4x4
