Answer:

Divide each side by -8

Distribute

Step-by-step explanation:

-8(n + 7) = -88.

Method 1

Divide each side by -8

n+7 = 11

Subtract 7 from each side

n = 4

Method 2

Distribute

-8n-56= -88

Add 56 to each side

-8n = -32

Divide by -8

n=4

Answer:

Distributive property & dividing -8 on both sides.

Step-by-step explanation:

You can begin solving the equation by either using the distributive property or dividing -8 on both sides.

Distributive Property:

\(-8(n+7)=-88\\-8n-56=-88\\-8n=-32\\n=4\)

Dividing:

\(-8(n+7)=-88\\n+7=11\\n=4\)

$-108.44

Step-by-step explanation:

Hey! Let's help you out with this question!

We always want to begin with what we know. We know that Jason has $284.31 on his lunch account and that during the year he mowed 13 lawns and earned $30 for each lawn. By the end, he spent $782.75 and now we need to figure out what his balance was at the end of the year. This can be split into 2 parts:

Part 1:

Let's start by how much money he has in total. We can take the current balance in his account of $284.31 and add the amount of money he made mowing lawns. We know that he mowed 13 lawns and earned $30 for each lawn. So, we can just chalk that total to be:

\(13*30=390\)

Based on our calculation, we know that he has earned $390 in total from mowing 13 lawns for $30 each lawn. Now that we have that, let's add that earning into his current balance and that'll give us:

\(284.31+390=674.31\)

Therefore, in total Jason has $674.31. including how much he earned from mowing lawns.

Part 2:

Now, we need to figure out Jason's account balance at the end of the school year. From here, we take the new total of Jason's account balance and subtract it from how much he spent on lunches throughout the school year. So, it would look like this:

\(674.31-782.75=-108.44\)

Unfortunately, Jason has spent too much on his lunches and his account balance at the end of the school year is $-108.44

Step-by-step explanation:

The surface area of the top open cylinder is 6810.149 sq.cm.

A cylinder is a three-dimensional solid that consists of two congruent surfaces (bases) and one lateral surface.

Surface area of a cylinder = Base area + Lateral area

Base area of a cylinder = 2 × π × r²

Lateral area of a cylinder = (2 × π × r) × h

Therefore, here base area of a cylinder = 2× π × 12²

                                                                  = 5837.27 sq.cm.

And, lateral area of a cylinder = (2 × π × 12) × 2

                                                  = 972.8784 sq.cm.

Therefore, total surface area of a cylinder = 5837.27 + 972.8784

                                                                      = 6810.149 sq.cm.

Answer: x = 0.22 cents

Step-by-step explanation: This is my first time trying to help someone so if I get something wrong I AM SO SORRY!!!!

First, find the unit rate of both companies.

To find company A's unit rate find what is the numerator and denominator. This is 65/13. We want a unit rate where 1 is in the denominator, so we divide the top and bottom by 13:

65 cents / 13

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

13 dollars / 13

Divide both by 13 and you get 5 cents per dollar.

Now find company B's unit rate. Find the numerator and denominator, 11/40.50. Now this time we want 1 where the denominator is again. So we divide the top and bottom by 40.5.

11 cents ÷ 40.5

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

40.5 dollars ÷ 40.5

Divide by 40.5 and you get 0.271605 cents per dollar. Round to the hundreths and get 0.27 cents per dollar

Now time to find how much company A charges more than company B. subtract 0.27 by 0.05 and you have your answer! x = 0.22 cents

Step-by-step explanation

For the first sum you nee to find the same coefficient or add or subtract a number

\(-x^3 -2x -7\)

This the simplified version of the sum above. I have basically subtracted -2x^3 by x^3 to make -x^3. Then I have subtracted -3x and x to make -2x. Finally I have added -4 and -3 as the rule suggests to add two numerals the minus symbol on both of them.

The next sum we have to simplify both numerals so we know if both sum’s answer are

\(-x^3 -2x -7-x^3 -2x -7\)

After simplifying them,  both of them have the same answer, so the statement is true. To explain this, we could say that the sums were basically rotated around to trick us but the answer is still the same

Answer:

The number is 32.

The equation is 32 - 9 = 23.

Explanation:

The original number is 32, but when you subtract 9, the number changes to 23. So the digits reversed.

The required number is 32 and the equation is 10x+y.

The sum of the digits of a two-digit number is 5. If nine is subtracted from the number, the digits will be reversed. To Find the number and the equation

In mathematics it deals with numbers of operations according to the statements.

Let the number at unit place is y and at tenth place is x so the number is
=10x+y
Now sum of the number is 5
x + y =5    -------(1)
When 9 is subtracted from the number, the digits will be reversed.
10x+y-9=10y+x
9x-9y=9
x-y=1    ------(2)

Solving equation 1 and 2
y = 2
x = 3
the number 10(3)+2 = 32

Thus, The required number is 32.the equation is 10x+y.

Answer:

Step-by-step explanation:

To solve the congruence 5x ≡ 6 (mod 7), we need to find a value for x that satisfies the equation.

First, we'll find the multiplicative inverse of 5 modulo 7. The multiplicative inverse of a modulo m is a number x such that ax ≡ 1 (mod m). In this case, we need to find a number x such that 5x ≡ 1 (mod 7).

To find the multiplicative inverse, we can try different values of x and compute the result until we find one that satisfies the equation. Alternatively, we can use a more efficient method like the Extended Euclidean Algorithm.

Using the Extended Euclidean Algorithm, we find that the multiplicative inverse of 5 modulo 7 is 3, as 5 * 3 ≡ 1 (mod 7).

Now, we can multiply both sides of the congruence by the multiplicative inverse (3) to isolate x:

5x ≡ 6 (mod 7)

3 * 5x ≡ 3 * 6 (mod 7)

15x ≡ 18 (mod 7)

Reducing the coefficients:

1 * x ≡ 4 (mod 7)

Since x ≡ 4 (mod 7), the solution to the congruence 5x ≡ 6 (mod 7) is x ≡ 4 (mod 7). This means that x can be written as x = 4 + 7k, where k is any integer.

Answer:

Ribeye (ea) = $18.54

Salmon (ea) = $9.78

Step-by-step explanation:

x is the price for each ribeye steak

y is the price for each grilled salmon

15x + 28y  = $551.97 (a)

24x + 14y = $581.91 (b) -----(x2)------> 48x + 28y = 1163.82 (c)

Subtract c with a

48x + 28y = 1163.82 (c)

15x + 28y  = $551.97 (a)

===================  -

33x           = 611.85

x = 18.54

Put the value of x into a

15 · 18.54 + 28y = 551.97

278.1 +28y = 551.97

28y = 273.87

y = 9.78

In conclusion, the price of 1 ribeye is $18.54, and the price of 1 salmon is $9.78.

Answer:

34.54

Step-by-step explanation:

So lets go over this.

In a circle, the line that goes straight through the middle of the circle and touches both sides is called the diameter, or d.

The radius is r, which is half the diameter, and on a circle, goes from the very middle of the circle to the side of the circle.

C is the circumference of the circle.

The formula for the circumference, C is \(\pi *2r\\\), or \(\pi *d\).

In our situation here, d is equal to 11 inches.

So if we plug that in we get:
\(\pi * 11 = 34.54\)

So 34.54 = c, our circumference.
