Hmm, so they seem to be increaeing by powers of 5
10=2 times 5
25=5 times 5
35=7 times 5
60=12 times 5
so maybe it is
nth term=5(n+2) or 5n+10
lets try it
0th term
5(0)+10
0+10=10
corrrect
3rd term
5(3)+10
15+10
25
correct
so the function is
f(x)=5(x+2)
The answer to your question is 8 hope it helps
Jim is 19
let fathers age be x then mothers age = x - 5 and Jim's age is 
(x - 5)
Total their ages and equate to 100
x + x - 5 + (x - 5 ) = 100
multiply through by 2 to eliminate the fraction
2x + 2x - 10 + x - 5 = 200
5x - 15 = 200 ( add 15 to both sides )
5x = 215 ( divide both sides by 5 )
x = 43
father is 43 years, mother is 38 and Jim is 19
Answer:
7.5
Step-by-step explanation:
Lets define what we're looking for, the "number", to be equal to x.
number = x
Following the questions hints:
" The sum of twice a number and three times a number"
(2x) + (3x)
is (which means equals to basically)
" triple the quantity of five more than a number"
3(x+5)
We connect all of this to find the number and get:
(2x) + (3x) = 3(x+5)
5x = 3x + 15
5x -3x = 15
2x = 15
x = 15/2
x = 7.5
A hopes that helps
Because with you divided 16 1.25
