Answer:
David's score= 160 ; Aaron's score = 55
Step-by-step explanation:
let Aaron's score be 'x'.
so, David's score will be 3x - 5
(3x - 5) + x = 215
3x + x - 5 = 215
4x = 215 + 5
4x = 220
x = 220/4
x = 55
therefore, Aaron's score = 55
David's score is (3x - 5) = (3*55) - 5 = 165 - 5 = 160
We can subtract from the number of strings of length 4 of lower case letters the number of string of length 4 of lower case letters other than x. Thus the answer is 264 − 254 = 66,<span>351</span>
*the table being referred to is attached below
Answer:
The table does not show a proportional relationship between variable g and h.
Step-by-step explanation:
For a proportional relationship to exist between two variables, there must be a constant, of which serves like a unit rate, when comparing two variables.
Thus, in the table attached below, there is no obvious constant of proportionality between variable g and variable h.
Thus,

F(x)+g(x) = (x+7) + (x-3) =
x + 7 + x - 3 =
