Evaluate:
-1 + 8(-9) -|-3-7

Answer:

C.50

Step-by-step explanation:

It would be 50 because there are 2 sides to the coin. So if you take 100/2 you get 50. that would be the best estimate answer in my opinion

Number of times the coin will land heads will be 50

Number of trials or observation when each trial has the same probability of attaining one particular value. It determines the probability of observing a specified number of successful outcome in a specific number of trial.

Here , number of times the coin had tosses: 100

P(probability of getting a head in a coin ) : number of time head can come when flipped once / total number of observations

 since , head can come once and there are two possibility either head or tail

hence P= 1/2

this implies number of times heads land up = n*P = 100 *(1/2) = 50

option c) 50

since each side is a -2y you do the opposite which is adding :)

hope this helped! Good luck!

The value of x after eliminating the variable y is -9.

The elimination method involves taking one variable out of the system of linear equations by using addition or subtraction along with multiplication or division of the variable coefficients.

Given that the two equations are 9x – 2y = – 75  and 2x – 2y = -12. The equations will be solved as,

9x – 2y = – 75  

2x – 2y = -12

The value of x will be calculated by elimination of the variable y,

9x – 2y = – 75  

-2x + 2y =+12

_____________

7x + 0 = -63

x = -9

Therefore, the value of x after eliminating the variable y is -9.

Step-by-step explanation:

Given parameters:

    Number that rode in columns = [tex]3\frac{2}{3}[/tex] times the number that rode in rows.

       2200 rode in columns

Unknown:

Number of people that rode in rows = ?

Solution:

  Let the number of people that rode in columns  = C

   Let the number of people that rode in rows  = R

                 C = [tex]\frac{11}{3}[/tex]R

Number of people that rode in rows  = 2200;

            2200 =  [tex]\frac{11}{3}[/tex]R

             11R  = 2200 x 3

                R  = [tex]\frac{2200 x 3}{11}[/tex]

                R = 200 x 3

               R  = 600

Number of people that rode in rows  = 600

Answer:

[tex]120in.^{2}[/tex]

To find the enlarged value, you have to multiply.

So, let's multiply 20 by 6, since it was enlarged by 6.

20 x 6 = 120.

So, the answer to the question is 120in.

Hope this helps you!

Answer:

Multiply 20 by 6 and then find the square of your answer

20×6=120

Answer:

Divide both sides by V

Step-by-step explanation:

The equation is not well written.

Mariko needs to solve the equation below for D. Here is the equation:

M = DV

For Mariko to get D, he needs to make D the subject of the formula by dividing both sides of the equation by the coefficient of D i.e V as shown;

Divide both sides by V

M/V = DV/V

V at the denominator will cancel out the V at the numerator to have:

M/V = D

Rearrange

D = M/V

Therefore, the statement which correctly describes the step he should take is:

Divide both sides by V. Option B is correct.

Answer:

8640

Step-by-step explanation:

All exterior angles must = 360 degrees.

There are 50 exterior angles, so it's logically concluded that there are 50 sides.

Interior angle= 180-7.2= 172.8

172.8 x 50= 8640.
