Jonas has $75 to spend on new clothes. The pair of jeans he wants costs $48.50. What is the most Jonas can spend on shirts?
Mice21 [21]

Answer:

The most Jonas can spend on shirts is $26.50.

Step-by-step explanation:

Given:

Money Jonas has to spend on new clothes = $75.

The cost of the pair of jeans = $48.50

Now, find the most amount which Jonas can spend on shirts.

So, to get the amount for shirts we subtract the cost of jeans from the total money to spend for new clothes:

⇒75-48.50 =\$26.50

So, Jonas remained with $26.50 to spend on shirts.

Therefore, the most Jonas can spend on shirts is $26.50.

Match each pair of polynomials to their sum.
Alex17521 [72]
<span>Answers:

(12x^2 + 3x + 6) + (-7x^2 – 4x – 2) = 5x^2 - x + 4

(2x2 – x) + (-x – 2x2 – 2) = -2x - 2 

(x3 + x2 + 2) +  (x2 – 2 – x3) = 2x^2 

(x2 + x) + (x2 + 8x – 2) = 2x^2 + 9x - 2

The mean salary of people living in a certain city is $37500 with a standard deviation of $1561. a sample of 33 people is select
Murrr4er [49]
The probability is 0.9671.

The z-score for this is given by

z = (x - μ)/(σ/√n)
z = (38000-37500)/(1561/(√33)) = 1.84.

Using a z-table (http://www.z-table.com) we see that the area under the curve to the left of, less than, this is 0.9671.

6y+4−3y−7=3(y−1) How many solutions are for this?
Kryger [21]

Answer:

Infinite amount of solutions.

General Formulas and Concepts:

  • Order of Operations: BPEMDAS
  • Regular + Equality Properties

Step-by-step explanation:

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

6y + 4 - 3y - 7 = 3(y - 1)

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

  1. Combine like terms:                         3y - 3 = 3(y - 1)
  2. Distribute 3:                                       3y - 3 = 3y - 3
  3. Subtract 3y on both sides:               -3 = -3

Here we see that there will be infinite amount of solutions. We can plug in any number <em>y</em> and it will render the equation true.
