Answer:

$13,800

Step-by-step explanation:

She sells the car for 115% of the value of the car, because she wants a 15% profit. 115% of 12000 is the same as 12000*1.15, since 115% is eqaul to 1.15. 12000*1.15 = 13800

x−(−16)=−28+12

x+16=−28+12

x+16=(−28+12)

x+16=−16

  • Solving systems of equations using substitution/elimination

Step-by-step explanation:

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

y = -8x

4x - y = 3

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

<em>Substitution</em>

  1. Substitute in <em>y</em>:                    4x - (-8x) = 3
  2. Simplify:                               4x + 8x = 3
  3. Combine like terms:           12x = 3
  4. Isolate <em>x</em>:                              x = 3/12
  5. Simplify:                               x = 1/4

<u>Step 3: Solve for </u><em><u>y</u></em>

  1. Define equation:                    y = -8x
  2. Substitute in <em>x</em>:                       y = -8(1/4)
  3. Multiply:                                  y = -2

Jason decided that he will sell his stocks if their value per share (x) goes below $5 or above $15. Which compound inequality re
Veronika [31]

Answer:

  B.  x < $5 or x > $15

Step-by-step explanation:

The "or" in the problem statement gives you a clue that answer choices C and D can be rejected.

If x is the stock value, then value per share "below $5" means x < $5. This corresponds with answer choice B. Of course, "above $15" means x > $15, also corresponding to answer choice B.

mestny [16]

Answer:

\begin{array}{cccccc}{x} & {V} & {W} & {X} & {Y} & {Z} & P(x) & {0.20} & {0.20} & {0.20} & {0.20} & {0.20} \ \end{array}

Step-by-step explanation:

Given

S = \{V,W,X,Y,Z\}

n(S) = 5

Required

The probability model

To do this, we simply calculate the probability of each container.

So, we have:

P(V) = \frac{n(V)}{n(S)} = \frac{1}{5} = 0.20

P(W) = \frac{n(W)}{n(S)} = \frac{1}{5} = 0.20

P(X) = \frac{n(X)}{n(S)} = \frac{1}{5} = 0.20

P(Y) = \frac{n(Y)}{n(S)} = \frac{1}{5} = 0.20

P(Z) = \frac{n(Z)}{n(S)} = \frac{1}{5} = 0.20

So, the probability model is:

\begin{array}{cccccc}{x} & {V} & {W} & {X} & {Y} & {Z} & P(x) & {0.20} & {0.20} & {0.20} & {0.20} & {0.20} \ \end{array}

A sofa is on sale for 73% off. The sale price is $172.80. What is the regular price?
Lapatulllka [165]
To get the answer you have to divide the sale price $172.80 by 73%.
So first you turn 73% into a decimal by moving the decimal two places to the left turning it into .73 

$172.80 divided by .73 = $236.71

You can check by then multiplying $236.71 with .73
