Tommy has a stamps. his sister has 5 more stamps. together they have 41 stamps. record using algebra.

Where a=Tommy's stamps

41=a+(5+a)

41-5a=2a

36=2a

18=a

(check Tommy has 18, his sister as 18+5=23. 18+23=41)

TOMMY HAS 18 STAMPS

Step-by-step explanation:

x = number of stamps for Tommy

Write an equation

x + x + 5 = 41

2x +5 =41

2x = 36

x = 18

  y= -3x is the required function.

step-by-step explanation:

we have been given a table:

x             y

0             0

1             -3

3             -9

-2             6

we can see that the values of y is -3 times the value of x

hence, the function would be: y= -3x.

put the values of x will give the same y as in the table that means function is satisfying the given table.

in if you ask questions, the points are taken from your total and given to the one who answered it..

so if i have 30 points and i ask a question for 5 points, then when someone asks a question i will lose 5 points and the answerer earns 5
