Solve the equation 2×-31=3(×+2)

Answers

Answer 1

Answer:

x=-37

Step-by-step explanation:

First, rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation:

                    2*x-31-(3*(x+2))=0

(2x - 31) -  3 • (x + 2)  = 0

Pulling out like terms

3.1     Pull out like factors :

  -x - 37  =   -1 • (x + 37)

Equation at the end of step

 -x - 37  = 0

Solving a Single Variable Equation:

4.1      Solve  :    -x-37 = 0

Add  37  to both sides of the equation :

                     -x = 37

Multiply both sides of the equation by (-1) :  x = -37

Answers

Based on the mean from the sample, I would expect that the number of guests that will stay at the small hotel than at the bed and breakfast would be 4.50.

How many more guests will stay at the small hotel than at the bed and breakfast?

Mean is the average of a set of numbers. It is determined by adding the numbers together and dividing it by the total number

Mean = sum of the numbers / total number

The number of guests at the small hotel in excess of those at the bed and breakfast = 7.75 - 3.25 = 4.50

To learn more about mean, please check: https://brainly.com/question/25842202

Answer:

315 more guests will stay at the small hotel than at the bed and breakfast in a 10-week period.

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

At the small hotel, a mean of 7.75 guest stay per night. 10 weeks have 70 days, then the total amount is:

S = 7.75 x 70 = 542.5

At the bed and breakfast, the mean was of 3.25 guests per night, hence:

B = 3.25 x 70 = 227.5.

The difference is given by:

S - B = 542.5 - 227.5 = 315.

Therefore, 315 more guests will stay at the small hotel than at the bed and breakfast in a 10-week period.

a .circle with diamter at (2,2) and (8,14

Answers

the equation of the circle with diameter at (2,2) and (8,14) is (x-5)^2 + (y - 8)^2 = 45

How to calculate the equation of a circle?

A circle is a 2-dimensional shape with no edges.

The standard equation of a circle with centre (a, b) and radius "r" is given as:

(x-a)^2 + (y-b)^2 = r^2

Given the diameter of circle with coordinate  (2,2) and (8,14), the diameter is expressed as:

D = √12² + 6²

D = √144+36
D = √180

For the radius

r = √180/2

r² = 180/4

r² = 45

Determine the centre (a, b)
(a, b) = (2+8/2 2+14/2)
(a, b) = (5, 8)

Substitute

(x-5)^2 + (y - 8)^2 = 45

Hence the equation of the circle with diameter at (2,2) and (8,14) is (x-5)^2 + (y - 8)^2 = 45

At a basketball game, a vendor sold a combined total of 197 sodas and hot dogs. The number of hot dogs sold was 41 less than the number of sodas sold. Find the number of sodas sold and the number of hot dogs sold.

Answers

Question : -

At a basketball game, a vendor sold a combined total of 197 sodas and hot dogs. The number of hot dogs sold was 41 less than the number of sodas sold. Find the number of sodas sold and the number of hot dogs sold .

Given : -

Total of sodas and hot dog sold = 197

No. of hot dogs sold = 41 less than the no. of sodas sold

To Find : -

No. of soda sold

No. of hot dog sold

Concept : -

We have to solve this question by making equation and after creating equations we have to solve them properly to get the final answer .

To Assume : -

Let the no. of soda sold be x .

Let the no. of hot dogs sold be x - 41 ( Because they are 41 less than sodas )

So Starting Solution : -

According to question we know that combined total of sodas and hot dogs is :

x + ( x - 41 ) = 197

x + x - 41 = 197

2x - 41 = 197

2x = 197 + 41

2x = 238

x = 238/2

x = 119

Therefore , No. of sodas sold is 119 .

Now , Hot dogs :

x - 41

119 - 41

78

Therefore , No. of hot dogs sold is 78 .

Verifying :

We know that their combined sum is equal to 197 . So ,

Sodas + Hot Dogs = 197

119 + 78 = 197

197 = 197

L.H.S = R.H.S

Therefore , our answer is valid .

The muffin recipe requires 2/3 cup more milk than the bread recipe.

What is subtraction?

Subtraction is a mathematical operation. Which is used to remove terms or objects in the expression.

To find out how much more milk is needed for the muffin recipe than the bread recipe,

we need to calculate the difference between the amount of milk required for each recipe.

The muffin recipe calls for 1 1/3 cups of milk, which is equivalent to 4/3 cups of milk.

The bread recipe calls for 2/3 cup of milk.

To find the difference between the two amounts of milk, we can subtract the milk required for the bread recipe from the milk required for the muffin recipe:

4/3 - 2/3 = 2/3

Therefore, 2/3 is the required fraction.
