7.5
The expression is: 15/n -2
15 - 2x
7.5
X divided by 4 - 10=2 x=48
x/4 - 4 = -2 Therefore, x/4 = -2 + 4 = 2 Therefore, x = 2 x 4 x = 8
2.5
A prime number can only be divided by itself and 1. 4 can be divided by 2 26 can be divided by 2 15 can be divided by 3
15 - 2x
7.5
8x/2 - 10 = 148x/2 = 248x = 48x = 6
3x + 15/2
(3n + 15) / 2
Because it can't be divided with the number 2.
X divided by 4 - 10=2 x=48
(3x+15)/2
Yes. All numbers that do not give a decimal-free number when divided by 2 are odd numbers. We get 15/2=7.5 => 15 is an odd number;)
x/4 - 4 = -2 Therefore, x/4 = -2 + 4 = 2 Therefore, x = 2 x 4 x = 8
Because when it is divided by 2 the remainder is 1.
