Step-by-step explanation:

We must ask a question that your answer corresponds to each of the topics in the statement, therefore we will review each one:

5. Distances members of the track team jogged last week

How far did you run last week?

6. Numbers of letters in name of street you live on

How many letters are there in the name of your street?

7. Cost of a restaurant dinner

How much did you pay for dinner?

8. Numbers of cars of different colors in a parking lot

What color is your car?

adam and betty purchased a printer together for $258. If adam paid $18 less than twice betty, how much money did Adam pay for th
LenKa [72]

Answer:

Step-by-step explanation:

Let A = Adam, B = Betty

Adam and Betty purchased a printer together for $258.

This means we can say A + B = 258.

We are also told Adam paid $18 less than twice Betty.

You can write this as:

Adam = 2 x Betty - 18

A = 2B - 18

Substitute "A" into the A + B equation and you get:

A + B = 258

2B - 18 + B = 258

3B - 18 = 258

Add 18 to both sides.

3B = 258 + 18

3B = 276

Divide both sides by 3 to find B

B = 276/3 = 92 (This means Betty paid $92).

Since the total that they paid together was $258.

This means Adam pays the Total - How much Betty paid

Adam = 258 - 92 = $166

1/2x^2 + 4x - 1 = 0<br> How to factor it
LenaWriter [7]

Answer:

x + 4 - 3√2 and x + 4 + 3√2

Step-by-step explanation:

When other methods seem to difficult to apply, try using the quadratic formula:

Here a = 1/2, b = 4 and c = -1.

Then the "discriminant" is b^2 - 4ac, or

(4)^2 - 4(1/2)(-1), or 16 + 2 = 18

Then the roots are:

     

      -4 ± √18, or -4 ± 3√2

and thus the factors are x + 4 - 3√2 and x + 4 + 3√2

x = ---------------------

Adding and Subtracting with Rational Numbers
stepladder [879]

Answer:

<h3>Part A</h3>

Net change is the change compared to zero level

  • From positive 2.2 feet to negative 2.4 feet
<h3>Part B</h3>

The distance between the elevations

  • 2.2 + 2.4 = 4.6 feet
<h3>Part C </h3>
  • 10 feet
<h3>Part D </h3>
  • 8.2 feet
<h3>Part E </h3>

Positive elevation brings the level close to the deck

  • 8.2 - 2.2 = 6 feet
<h3>Part F</h3>

Negative elevation takes the level apart from the elevation of the surf shop

  • 10 - (-2.4) = 12.4 feet
  • The surf shop was higher
