Answer:

  11·11^4

Step-by-step explanation:

The applicable rules of exponents are ...

  (a^b)(a^c) = a^(b+c)

  a = a^1

  (a^b)/(a^c) = a^(b-c)

  a^0 = 1 . . . . for any 'a' not 0

__

The given expression is ...

  (11^8)/(11^3) = 11^(8-3) = 11^5

The offered choices are ...

  (11^7)/(11^7) = 11^(7-7) = 11^0 = 1

  11·11^4 = (11^1)(11^4) = 11^(1+4) = 11^5 . . . . matches the given expression

  (11^0)/(11^5) = 11^(0-5) = 11^-5

  11^0 = 1

Answer:

x+65≤84

Step-by-step explanation:

Inequality that represents the number 'x' of additional people who can enter the restaurant​ is -

x + 65 ≤ 84

Inequality refers to a relationship that makes a non-equal comparison between two numbers or other mathematical expressions.

Given is a restaurant which has 65 people in it. The restaurant has a maximum capacity of 84 people.

Assume that 'x' more people can enter inside the restaurant. Then -

the inequality can be written as follows -

x + 65 ≤ 84

65 people were already inside. 'x' more people can enter it such that the total number of people inside is either less or greater than 84.

Therefore, inequality that represents the number 'x' of additional people who can enter the restaurant​ is -

x + 65 ≤ 84

Answer:

Answer:

The answer is negative one half. If I am wrong let me know because the picture is a little hard to read.

Step-by-step explanation: To find the slope, you look at the Y axis and see where the line crosses perfectly(or goes through) the Y axis first. Then, you look at the x axis and see where the line crosses perfectly on the x axis. For example, the line crosses the Y axis at negative, and the line crosses the X axis at positive 2.  The vertical line is the y axis and the horizontal line is the x axis.

Answer:

you times the number by itself the number of times the power is. 10 to the fourth power is 10 times 10 times 10 times 10, etc.

Step-by-step explanation:

For instance 10 to the third power is 1000 because 10 times 10 times 10=1000/

For your example the answer is 2 times 2 times 2 times 2=16. To figure out how much you times it by is if it is to the power of 4, you times it by itself 4 times, power of 5 = times it by itself 5 times, etc. Hope it helps!

Answer:

Then common factor is 16

Step-by-step explanation:

The factored expression is equivalent to -

8(6 + 10)

In mathematics, the greatest common divisor of two or more integers, which are not all zero, is the largest positive integer that divides each of the integers.

Given is to factor the given expression using the greatest common factor A = 48 + 80

For -

48 = 2 x 2 x 2 x 2 x 3

80 = 2 x 2 x 2 x 5

Using the greatest common factor, we can write -

48 + 80

8(6 + 10)

Therefore, the factored expression is equivalent to -

8(6 + 10)

Answer:

7.9

Step-by-step explanation:

When a number (or multiple numbers) is placed between two lines like this | |, that is the absolute value grouping symbol. Absolute value is the distance between the grouped number(s) and another defined number. In this case there are no other given numbers so 0 is assumed.

Now, say a friend is driving to your house and you call them to ask how far away they are from arriving (in distance), and they say "Around negative 5 miles away." That doesn't make sense! Distance can never be negative, and because absolute value is the distance between a number and another, a number within that grouping symbol can never be negative if there is a solution. Therefore, |-7.9| would be 7.9, because -7.9 is that exact amount away from 0.

Answer:

It's A

Step-by-step explanation:

Answer:

-1

Step-by-step explanation:

Original Equation:

3n - 5 = -8(6 + 5n)

Use distributive property on the parentheses.

-8 ⋅ 6 = -48

-8 ⋅ 5n = -40n

Equation now:

3n - 5 = -48 - 40n

Add 40n to both sides.

43n - 5 = -48

Add 5 to both sides.

43n = -43

Divide both sides by 43

n = -1
