Lisa is 53 3 4 inches tall. Joey is 1 1 2 inches shorter than Lisa and Jane is 1 1 5 inches shorter than Joey. How tall is Jane?

tester [92]

Answer: Jane's height = $51\dfrac{1}{20}\text{ inches}$

Step-by-step explanation:

Given: Lisa's height = $53\dfrac34\text{ inches}=\dfrac{4\times53+3}{4}\text{ inches}$

$=\dfrac{215}{4}\text{ inches}$

Joey's height = $\dfrac{215}4-1\dfrac12$ inches

$=\dfrac{215}4-\dfrac32\\\\=\dfrac{215-6}{4}\\\\=\dfrac{209}{4}\text{ inches}$

Jane's height = $\dfrac{209}{4}-1\dfrac15$ inches

$=\dfrac{209}{4}-\dfrac{6}{5}\\\\=\dfrac{209\times5-6\times4}{20}\\\\=\dfrac{1045-24}{20}\\\\=\dfrac{1021}{20}\\\\=51\dfrac{1}{20}\text{ inches}$

Hence, Jane's height = $51\dfrac{1}{20}\text{ inches}$

Jennifer is twice as old as laurel, who is 4 years younger than nana. If nana is two years younger than Jennifer what is nana’s

shutvik [7]

Nana's age: 10 years

Step-by-step explanation:

Here we call:

J = Jennifer's age

L = Laurel's age

N = Nana's age

We have the following information:

- Jennifer is twice as old as laurel, so

J = 2L (1)

- Laurel is 4 years younger than Nana, so

L = N - 4 (2)

- Nana is 2 years younger than Jennifer, so

N = J -2 (3)

Substituting (2) into (1),

J = 2(N-4) = 2N - 8

And substituting this into (3) and solving for J, we find Nana's age:

N = (2N-8) - 2

N = 2N - 10

N = 10

Which means that Jennifer's age is:

J = N + 2 = 12

And Laurel's age is

L = J/2 = 6
