Answer:

b = 24/5

General Formulas and Concepts:

<u>Pre-Alg</u>

  • Order of Operations: BPEMDAS
  • Equality Properties

Step-by-step explanation:

<u>Step 1: Define equation</u>

12 = 5/2b

<u>Step 2: Solve for </u><em><u>b</u></em>

  1. Rewrite:                                        5/2b = 12
  2. Divide both sides by 5/2:            b = 24/5

<u>Step 3: Check</u>

<em>Plug in b to verify it's a solution.</em>

  1. Substitute:                    12 = 5/2(24/5)
  2. Multiply:                        12 = 12

Liana is studying the activity of nurse sharks. She starts at a position that is 25 feet below sea level. She rises 9 feet, then
Reil [10]

Answer:

I believe the answer is -28

Step-by-step explanation

I gotchu bro

The answer is -28 because Liana starts at 25 below sea level (which is the same thing as -25) If she rises 9 feet, then you know to add because she is going up so your just gonna add. Next she descends 12 feet, so she went down, so subtract. So i know the answer is going to be -28 because -25+9 is -16, then imma subtract -16 and 12 so, -16 - 12= -28. There ye go

the population of masterton was 23 000 in 2012. Assume that Masterton population increases at a rate of 2% per year. Write an eq
Oksanka [162]
So, let's first focus on the first year:

the population then would be: 23000* (100+2)%

100% is the old population the 2% is the incease, so in total it's 102%, or 1.02 - the same number written differently.

So it will be 23000*1.02

After two years it will be 23000*1.02*1.02, and so on

so after x years it will be:

y=23000*1.02^{z}

James built a small electric car and recorded the distance it traveled. The table below shows the distance traveled (n) during t
Scrat [10]
<span>Table

Elapsed Time (seconds) Distance Traveled (feet)

1                                         6.2

2                                        12.4

3                                        18.6

4                                         24.8

Explanation:

You can check that 6.2 / 1 = 12.4 / 2 = 18.6 / 3 = 24.8 / 4 = 6.2

So, the relationship between the distance traveled and the time elapsed is a constant:

distance traveled / time elapsed = 6.2

n / f = 6.2

=> n = 6.2 f

Answer: n = 6.2 f
