Pamela's age is two times jiri's age. the sum of their ages is 51. what is jiris age?

Jiri is seventeen years old.

J=Jiris

P=2J

P+J-51

Use substitution to solve

2J + J = 51

3J = 51

J=17

Plug 17 into one of the equations

J=17, P + J = 51

P + 17 = 51

P= 34

So Pamela is 34 and Jiris is 17

arithmetic sequence

step-by-step explanation:

given that a sequence has terms as

19, 15, 11,

this is represented on a graph

the pattern indicates that the sequence is an arithmetic sequence with i term

a=19 and common difference d =-4

any general term

thus the sequence is reduced by 4 for each successive term starting from 1 and nth term is

24-5n.

first negative term would start after 5th term

5th term =24-25< 0

from 5th term onwards the sequence would be negative.

the entire expression should be subtracted from 30. to subtract the quantity, distribute the negative sign, which changes the signs on the terms. so, the –2 changes to positive and gets added to 30 instead of subtracted from it.

hope this ! ^w^
