Answer:

6

Step-by-step explanation:

Answer:

z=-16

Step-by-step explanation:

-7 = (z/2) + 1 Original equation

-7-1 = (z/2) Combining like terms

-8 = z/2 Simplification

-8 × 2 = (z/2) × 2 Isolating the variable

-16 = z The answer

Check your answer

-7 = (-16/2) + 1 Substitution

-7= -8 + 1 Simplify

-7 = -7 Your answer is right

Hope this helped!!!

Answer:

subtract 2a + 3b - 3b =5 - 3b

simply 2a = 5 -3b

divide both sides by 2 . 2a over 2 = 5 over 2 - 3b over 2

simply a= 5- 3b over 2

Answer:

1) At least two equal sides

2) One pair of equal angles

The parametric equations that models the path of the rider are:

This refers to the type of equation that makes use of a parameter to define dependent variables.

Hence, we can see that to model the path of the rider, the parametric equation that can be best used is to model the direction of the bicycle which is moving 5 miles east and then continues 8 miles north, and the fact that they started at rest 0 and the equations to make the model are:

People should rescue animals from pet stores.

Step-by-step explanation:

An argument is a series of propositions that is organized in such a way that the final proposition appears to be a conclusion which is intended to obey the logical concept of the prior propositions that function as the premise. From "The Case for Shelter Animals", the sentence that best conveys the argument tells us that People should rescue animals from pet stores.

2w=36

Answer:

Step-by-step explanation:

This may be confusing but bear with me

20=(x+17+22+18+21)/5 is our equation because

20 is our mean and we are adding all of our values and diving by how many values we have. we have 5 values

we multiply 5 by 20 to cancel the dividing 5 on the right so

100=x+17+22+18+21

To make this simpler we can add all of the values (except x) so

100=x+78

lets subtract 78 from 100

22=x or x=22

Correct choice is D

Answer:

D. 9 mm³

Step-by-step explanation:

Dimension of the prism

= 3 * 4* 6

side of each small cube

= 1/2 mm

In terms of number of small cubes , volume of the prism = 3 *4 * 6= 72

Volume of each unit of cube

= (1/2)³

Answer:

No, because grabbing the math book changed the odds of grabbing the notebook.

These are not independent events as you didn't replace the first book so that changed the probability that you would draw a notebook second , Option C is the answer.

Probability is the likeliness of an event to happen.

It is given that there are three math books, two science books, and five notebooks.

Total number of books = 3 + 2 + 5 = 10

The probability of drawing a mathbook is 3 / 10 = 0.3

and then if the mathbook is not replaced then the total outcomes for drawing a notebook changes.

Therefore they are not independent events and Option C is the answer.
