Answer:

Answer:

$|x-1|<3$

Step-by-step explanation:

You are given

$-2<x<4$

$-2-1<x-1<4-1\n \n-3<x-1<3$

Now, rewrite it using absolute value:

$|x-1|<3$

Sara Just Turned 18 Years Old. She Spent 4/9 Of Her Life Living In Rochester,NY. How Many Years Did Sara Live In Rochester?

8 years

Further explanation

Given:

Sara just turned 18 years old.

She spent $(4)/(9)$ of her life living in Rochester, NY.

Question:

How many years did Sara live in Rochester?

The Process:

From the information above, we make a suitable diagram as follows:

$\boxed{\cdot}\boxed{\cdot}\boxed{\cdot}\boxed{\cdot} = ? \ years$

Four of the nine parts are the question. The nine full parts below are Sara's ages.

$\boxed{\cdot}\boxed{\cdot}\boxed{\cdot}\boxed{\cdot}\boxed{\cdot}\boxed{\cdot}\boxed{\cdot}\boxed{\cdot}\boxed{\cdot} = 18 \ years$

Let us calculate how many years did Sara live in Rochester.

$\boxed{ \ 9 \ parts = 18 \ }$
$\boxed{ \ 4 \ parts = ? \ }$

$\boxed{ \ = (4)/(9) * 18 \ }$

We crossed out 9 and 18.

$\boxed{ \ = 4 * 2 \ }$

Thus Sara has lived in Rochester for $\boxed{\boxed{ \ 8 \ years \ }}$

Quick Steps:

$\boxed{ \ = (4)/(9) * 18 \ }$

$\boxed{ \ = 4 * 2 \ }$

$\boxed{\boxed{ \ 8 \ years \ }}$

Sue And Juanita Were Biking On The Track Around Their Town Park. Sue Started First. When She Had Biked 9 Laps, Juanita Had Biked 3 Laps. When Juanita Had completed 12 laps, Sue had completed 30 laps. did both rates remain steady

Answers

Answer:

No. Both rates did not remain steady.

Step-by-step explanation:

When Sue had biked 9 laps, Juanita had biked 3 laps. This means that Juanita's rate is 3 laps for every 9 laps Sue bikes.

When Juanita had completed 12 laps, Sue had completed 30 laps. This implies that Sue's rate is 30 laps for every 12 laps Juanita bikes.

In conclusion, the rates did not remain steady because Sue's rate was significantly faster than Juanita's.

No both rates did not remain steady
