Answer:
Step-by-step explanation:
Let k represent Kim's age. Then Jack's age is k-5 and the total of their ages is ...
k + (k -5) = 21
2k = 26 . . . . . . . add 5, collect terms
k = 13 . . . . . . . . . divide by 2; Kim's age
k -5 = 8 . . . . . . . Jack's age
Kim is 13; Jack is 8.
Showing fractions with models is giving a visual and sometimes can be easier to process.They also can be in picture form or other.Ex. A piece of pizza cut into fourths.
Showing fractions on a number line is also giving a visual but still allows you to add and subtract using numbers if that makes sense.Ex.

1/3 2/3 3/3
D) 34/5 because 6(5) = 30 30+4=34 , so its 34/5
Answer:
456
Step-by-step explanation:
Number of chairs around the round tables = 6×7=42
Number of chairs around the rectangular tables =23×18=414
The total number of chairs in the cafeteria = 6×7+23×18=456
Answer:
The required recursive formula is:
Step-by-step explanation:
We are given a geometric sequence as:
6,-18,54,-162,.....
Clearly after looking at different terms of the sequence we could observe that the sequence is an geometric progression (G.P.) with common ratio= -3 denoted by r.
Let 
represents the nth term of the sequence.
This means that:
As the common ratio is -3.
so,
Hence, the required recursive formula for the geometric sequence is:
