Some people advise that in very cold weather, you should keep the gas tank in your car more than half full. Lou's car had 5.9 gallons in the 13-gallon tank on the coldest day of the year. Lou filled the tank with gas that cost $3.80 per gallon. How much did Lou spend on gas?

Answers

Answer 1

Answer:

Lou spends the total amount would be $26.98 on gas which is determined by subtracting 13 gallons and 5.9 gallons and multiplying the result by $3.80.

What are Arithmetic operations?

Arithmetic operations can also be specified by adding, subtracting, dividing, and multiplying built-in functions.

* Multiplication operation: Multiplies values on either side of the operator

For example 4*2 = 8

The following information is provided in the problem :

Lou topped up the tank with $3.80 per gallon of petrol.

Lou's car's 13-gallon tank held 5.9 gallons.

If he filled the tank, you can determine the total amount of money Lou spent by subtracting 13 gallons and 5.9 gallons and multiplying the result by $3.80.

So the total amount would be:

⇒ (13 - 5.9)(3.80)

⇒ (7.1)(3.80)

⇒ 26.98.

Therefore, the total amount would be $26.98

The tables represent two linear functions in a system. A 2 column table with 5 rows. The first column, x, has the entries, negative 4, negative 2, 0, 2. The second column, y, has the entries, 26, 18, 10, 2. A 2 column table with 5 rows. The first column, x, has the entries, negative 4, negative 2, 0, 2. The second column, y, has the entries, 14, 8, 2, negative 4. What is the solution to this system? (1, 0) (1, 6) (8, 26) (8, –22)

Answers

We want to solve a system of linear equations, we will get that the solution is (8, -22)

A system of equations is a group of equations that we must solve simultaneously.

Here we have two lines defined by tables:

line 1:

x y

-4 26

-2 18

0 10

2 2

line 2:

x y

-4 14

-2 8

0 2

2 -4

Remember that a line is written as:

y = a*x + b

Where a is the slope and b is the y-intercept.

We know that if a line passes through the points (x₁, y₁) and (x₂, y₂), then the slope can be computed as:

$a = (y_2 - y_1)/(x_2 - x_1)$

With this we can find the slope of the first line, using any pair of the given points, I will use (0, 10) and (2, 2)

$a = (2 - 10)/(2 - 0) = -4$

And we know that the line passes through (0, 10), then the y-intercept is equal to 10.

y = -4*x + 10

For line 2 we can use the points (0, 2) and (2, - 4), so we get:

$a = (-4 - 2)/(2 - 0) = -3$

And the y-intercept is y = 2, then the line is:

y = -3*x + 2

Now we must solve:

-4*x + 10 = -3*x + 2

10 - 2 = 4x - 3x

8 = x

Now we evaluate x = 8 in any of the two lines:

y = -3*8 + 2 = -22

Then the solution of the system is (8, -22)

How to round 8,230 to the nearest thousand

Answers

8,230. Look at the eight. Now look at the number BEHIND it. If the number is 4 or LOWER, then turn that number into a zero. If it is 5 or HIGHER, then turn the number behind it into the number that comes after. For example: 8,230. 2 is lower than 4, so the answer is 8,000. :-D

it is 8000 because 230 is not over 500
