Answer from: santosv3136

Answer with Step-by-step explanation:

We are given that Shelly and Kristen share a birthday

Let x be the age of Kristen and y be the age of Shelly.

Age of Shelly= y=x+5

a.We have to make a table showing ages of Shelly and Kristen.

Suppose, Kristen was born in year 2000.

x=0 then y=5

Now, the age of Shelly and Kristen increases by every year by 1.

b.If age of Kristen=16 years

We have to find the age of Shelly

Substitute x=16

y=16+5=21 years

c.Age of Kristen =K years

We have to find the age of Shelly.

Substitute x=K

Then, we get

Age of Shelly= y=K+5 years

d.Age of Shelly=S years

We have to find the age of Kristen.

Substitute y=S then we get

S=x+5

x=S-5

Hence, age of Kristen= y=S-5 years

Shelly and kristen share a birthday, but shelly is 5 years older. a. make a table showing their ages

Answer from: Quest

The question is kind of confusing. if it's asking how many variations of answers can you give. then do 4^5 for your answer.this would be something like the first question could be a and the 2nd c or first b next c etc. if you can, ask the teacher for a better confirmation of what it's asking. if i'm assuming correctly what it's asking, it's 625 different variations.
