Atomic number tells you the number of ______________ contained in the nucleus of an atom. Which is always equal to the number of _____________ in an atom.

5 = -2 (x –  1)  (remove the parantheses)

5 = -2x + 2 (move the terms)

2x = 2 - 5 (calculate)

2x = -3 (divide both sides)

x= -3/2

5= -2x + 2 (move the terms)

2x = 2 - 5 (calculate)

2x = -3 (divide both sides)

x= -3/2

Step-by-step explanation:

Answer:

1. a

2. b

3. c

Step-by-step explanation:

1. a

For this first graph, we know that it matches a because of the domain. A tells us that the x≠-1. We know this because of the denominator.

(x+1)(x+1)=0          subtract both sides by 1]

x=-1

Therefore, a matches graph 1.

------------------------------------------------------------------------------------------------------

2. b

For graph 2, we can see that the graph is under the x-axis, meaning it is all negative. The only option that gives us a negative point is b. You can tell by the negative sign in front of the square root.

Therefore, b matches graph 2.

------------------------------------------------------------------------------------------------------

3. c

For graph 3, we see that everything is above the x-axis, meaning the graph is always positive. The option that fits this is c. In c, there are absolute values. Absolute values tell us that the answer is always going to be positive.

Therefore, c matches graph 3.

Provided in the question, total number of people that can be accommodated in the theatre are 471.

Then, according to the question there are two possibilities. The number of people is less than the total number of People who can be accommodated.

[tex]1) \: p + 254 < 471[/tex]

Or, they can be equal to the number of people.

[tex]2) \: p + 254 = 471[/tex]

Combining both the inequations, We get

[tex] \boxed{ p + 254 \leqslant 471}[/tex]

So, the correct option is Option D

Step-by-step explanation:

In miles it is 29,035 / 5280

= 5.5 miles.

In kilometers it is 5.5 / 0.621 kilometres

= 8.857 km.

= 8857 m.

Answer:

In miles it is 29,035 / 5280= 5.5 miles I umm belive

Step-by-step explanation:

x = # of miles

$59.31 = $31 + $0.19x

Subtract $31 from both sides

$28.31 = $0.19x

Divide both sides by $0.19

149 = x

Answer:

A, B, and D

Step-by-step explanation:

A would be a correct answer since the book was 94 pages shorter than expected, so it was -94 pages of what was expected.

B would be a correct answer since Andrew no longer has that $94. His account would show a transaction of -$94.

C would not be a correct answer since the temperature was a positive number. For it to have been a correct answer, the temperature would've had to have been -94.

D would be a correct answer since Jennifer no longer has 94 apples. She now has a value of -94 apples compared to the value she had before she started selling them.

Answer:

49

Step-by-step explanation:

First, multiply 5 on both sides:

2n = 50

Then, we divide 2 on both sides:

n = 25

Now we got the value of n, let's calculate 2n - 1.

First, multiply 2 by n so we can get 2n:

2 * 25 = 50

Then, we calculate 50 - 1:

We got 49, and that's the answer ^^

Hope this helps!

The value of 2n-1 is 49 if 2n/5=10, after applying the concept of a linear equation and the value of n is 25.

It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.

If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.

It is given that:

2n/5 = 10

2n = 50

n = 25

Plug the value of n in the expression 2n - 1

= 2(25) - 1

= 49

Thus, the value of 2n-1 is 49.

v=16+11(2) Do multiplication first

v=16+22

v=38

Answer:

38

Step-by-step explanation:

1. Plug in the each number for its variable to get v = 16 + 11 x 2

2. Multiply 11 and 2 to get 22

3. add 16 to 22 to get 38

We know 3x16=48

Since there is a minus sign, the answer is -48.

Answer:

Change in elevation= 431 feet/mile marker

Step-by-step explanation:

given data

Elevation at mile marker 4 = 6135 feet

Elevation at mile marker9 = 8290 feet

to find out

average change in elevation

solution

we get here average change in feet per mile marker  that is express as

average change in feet per mile = change in elevation ÷ change in mile marker     .....................1

put hree value we get

average change in feet per mile = [tex]\frac{8290-6135}{9-4}[/tex]  

average change in feet per mile = 431 feet/mile marker

so

Change in elevation= 431 feet/mile marker

The equivalent fractions for 2/3 are 6/9, 10/15, and 12/18 because multiplicative identity is a feature of multiplication that is used to determine equivalent fractions.

Fraction number consists of two parts, one is the top of the fraction number which is called the numerator and the second is the bottom of the fraction number which is called the denominator.

It is given that:

2/3 by multiplying by 3/3, 5/5, and 6/6.

= (2/3)(3/3)

= 6/9

= (2/3)(5/5)

= 10/15

= (2/3)(6/6)

= 12/18

The multiplicative identity is a feature of multiplication that is used to determine equivalent fractions.

The numerator and denominator of a fraction are multiplied by the same number for determining equivalent fractions.

Thus, the equivalent fractions for 2/3 are 6/9, 10/15, and 12/18 because multiplicative identity is a feature of multiplication that is used to determine equivalent fractions.

Answer:

7 hours.

Step-by-step explanation:

6x7=42

42+18=60

For number of hours Jimmy rented the bike Krystal's bikes is 8 hours.

In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.

Given that, Jimmy rented a bike from Krystal's bikes. It costs $18 plus $6 per hour and Jimmy paid $60.

Let the number of hours be x.

Now, 18+6x=60

6x=42

x=8

Therefore, for number of hours Jimmy rented the bike Krystal's bikes is 8 hours.
