If you add positive 5 and positive 5, you'll get positive 10.
If you add positive 5 and negative 5, you'll get positive 0.
If you add negative 5 and negative 5, you'll get negative 10.

-5 + 5 = -5 + 5
5 + 5 = 5 + 5
- 5 + -5 = -5 + -5

a person bought two watches for 2500, she sold one of them at 10% profit & the other one at 4% loss. what was her gain or lo
Zepler [3.9K]

Answer:

profit : RS 150 and profit % : 3%

Step-by-step explanation:

for profit 10% for loss 4%

s.p will be 2750. s.p will be 2400

Total s.p : 2750 +2400. total s.p : 5150

profit = s.p-c.p. profit%=?

=5150-5000. profit = p /c.p × 100

=150 = 150/5000×100

= 3%

In a gambling game, you roll 2 die and if you toss 2 sixes, you win $100, otherwise you lose $5.
Natalka [10]

Answer:

a. \frac{1}{36} chance you win.

b. The expected value of the game is -$2.08.

Step-by-step explanation:

A probability is the number of desired outcomes divided by the number of total outcomes.

You roll 2 die and if you toss 2 sixes

For each roll, 6 possible values, 1 of which is 6. So the probability of rolling two sixes is:

p = (\frac{1}{6})^2 = \frac{1}{36}

a. What is the chance you win?

\frac{1}{36} chance you win.

b. What is the expected value of the game?

1/36 probability of winning 100.

35/36 probability of losing 5. So

E = \frac{1}{36}*100 - \frac{35}{36}*5 = \frac{100 - 175}{36} = -\frac{75}{36} = -2.08

The expected value of the game is -$2.08.

Find an ordered pair that is a solution to the equation.<br><br> 3x - y = 8
mojhsa [17]

Answer:

Step-by-step explanation:

There are so many order pairs that can solve this equation.

To solve this problem, we choose any value of x and find y;

  Given expression;

            3x  - y  = 8

 if x  = 0,

           3(0) - y  = 8

                 -y  = 8

                 y = -8;

  (0,-8) is a solution

ii.

  if x  = 1,

          3(1) - y = 8

               - y = 8 - 3

                  y = -5

        (1, -5) is a solution

7n^2-4n-14=21<br> complete the square
Galina-37 [17]
Answer: (7n - 2)² = 249

Explanation:

1) Given expression: 7n² - 4n - 14 = 21

2) Transpose  - 14 =>

7n² - 4n = 21 + 14

3) Combine like terms =>

7n² - 4n = 35

4) multiply both terms by 7 =>

(7n)² - 4(7n) = 35×7

5) form the squared binomial:

(7n - 2)² - 4 = 35×7

6) Transpose - 4 =>

(7n - 2)² = 35×7 + 4

7) Do the operations on the right side:

(7n - 2)² = 249 or (7n - 2)² - 249 = 0

8) Verify the equivalence by expanding the binomial:

(7n)² - 2(7n) + 4 - 249 = 0

(7n)² - 14n - 245 = 0

Divide by 7: 7n² - 2n - 35 = 0 or 7n² - 2n = 35, which is equivalent to the given expression.
