What is the value for x? 8x-13 and 5x+14

Answers

Answer 1

Answer:

9

Step-by-step explanation:

8x-13=5x+14

you subtract 5x from both sides and get

3x-13=14

then add 13 to both sides  and get

3x=27

then divide 3 from both sides

3/3=x

27/3=9

x=9

Answer 2

Answer:

x = 9

Step-by-step explanation:

8x - 13 = 5x + 14                                                                                                                                Subtract 5x from both sides of the equation                                                                    3x - 13 = 14                                                                                                                          Add 13 to both sides of the equation                                                                            3x = 27                                                                                                                                     Divide by 3 for both sides of hte eqation                                                                        x = 9

Step-by-step explanation:

I used process of elimination to determine which one fits.

here's how I know I'm correct:

the rule is, y = 4x - 7

if you put in the numbers from table 2

-3 = 4(1) - 7

-3 = 4-7

-3 = -3

How does the side length of the square relate to the square root?

Answers

Answer:

The sides can be found by taking the square root of the area. , where = side.

Step-by-step explanation:

Answer:

the area of any quadrilateral can be determined by multiplying the length of its Base by its height. since we know the shape here is square we know that all sides are of equal length. from this we can work backwards by taking the square root of the area to find the length of one side.

Mr. and Mrs. Wagner are getting ready to drive across the USA from Philadelphia, PA to Los Angeles, CA in five days. The distance is approximately 3,000 miles. The average price of gasoline is about $2.10 per gallon. They plan to stay in a hotel for four nights and budget the cost of meals be about $45 per day per person.

Answers

Answer:

(a) $ 84.

Step-by-step explanation:

Given that, the distance between the PA to CA = 3000 miles.

Time of travel, t = 5 days.

The average price of gasoline, r = $ 2.10/ gallon

Cost of meal for one person, c = $ 45/ day

Total number of persons, n = 2 (Mr. and Mrs. Wagner)

(a)  The average of van = 75 mpg.

So, to cover 75 miles, the amount of gasoline required = 1 gallon

By using the elementary method, the amount of gasoline required to cover 1 mile = 1/75 gallons.

So, the amount of gasoline required to cover 3000 miles

= (1/75)x 3000= 40 gallons.

Now, cost for gasoline = 40 x 2.10=$84

Hence, the total cost of the gas for the trip is $84.

Express the statement "A rectangular field with an area of 120m' has it length 12mn longer than the width" as quadratic equation.

Answers

Answer:

The quadratic equation is x^2 -12x -120 = 0

where x represents the length of the field

Step-by-step explanation:

We want to make an expression in terms of a quadratic equation;

Let the length of the field be x mm , then the width will be (x-12) mm

Mathematically , the area of the field will be L * B

Thus;

x * (x-12) = 120

That gives;

x^2 -12x = 120

x^2 -12x -120 = 0
