What is the percent change if you paid $1.87 per gallon on February 6th and $1.80 per gallon on February 17th?

The solution for the equations x = 1 and y = 3

A system of linear equations is a collection of at least two linear equations.

In this case, the system of equations is given as

x + y=4

-x + y = 2

Add the equations

So, we have

2y = 6

Divide both sides by 2

y = 3

Substitute y = 3 in x + y = 4

x + 3 = 4

Evaluate

x = 1

Hence, the solution for the system of linear equations x + y=4 and -x + y = 2 are x = 1 and y = 3

The inequality is given to be:

Recall the Absolute Rule:

Applying this to the inequality, we have:

or

Therefore, the solution to the inequality is:

The (equivalent) compound annual rate at which Anders' salary has grown during the 12 years is 4.9%.

The compound annual rate is the equivalent rate of interest at which the present value of money grows to attain a future value.

At a 4.9% compound annual rate, Anders' salary has been growing by adding the growth amount to the initial salary and compounding both the principal and subsequent interest amounts until 12 years.

N (# of periods) = 12 years

PV (Present Value) = $2,800

PMT (Periodic Payment) = $0

FV = $-4,971.23

Results:

I/Y (Interest per year) = 4.9%

Total Interest = $2,171.23

Thus, using the online finance calculator, we can determine that Anders' salary has been compounded at 4.9% annually.

In the metric system, centimeters per minute (cpm) represents speed or velocity. It counts the centimeters that are covered in a minute.

65 mi/hr to 174346 centimeters per minute.

$1 mi/h = 2682.2346355307 cm/ min.

65 × 2682.2346355307 cm/min = 174345.2513095 Centimeters Per Minute.

Always check the results; rounding errors may occur.

The base unit of [speed] (meters per second), 1 Miles Per Hour (mi/h) exists equivalent to

0.44704 meters-per-second,

while 1 Centimeters Per Minute (cm/min) = 0.000166667 meters-per-second.

65 Miles Per Hour to common speed units

65 mi/ h = 65 miles per hour (mi/h)

65 mi/h = 1.0833333333333 miles per minute (mi/m)

65 mi/h = 174346 centimeters per minute

Therefore, the correct answer is 174346 centimeters per minute.

Dependent events: The likelihood of one event happening influences the likelihood of the other event happening.

When the result of one event affects the result of another, two events are said to be dependent events.

The likelihood of two connected events is the sum of the probabilities of the occurrences X and Y that happen after X.

The likelihood of one event does influence the likelihood of the other happening.

The value of absolute inequality will be given by 0.002 ≥ |x-3|.

Inequality may be defined as the expression which shows unequal behavior between two entities while absolute inequality expression includes inequality along with an absolute value. For example, |x| > 3, |x| <3, |x| ≤3 or |x| ≥3. Now, let us assume the length of the part in the question as x. Since, the desired length is given as 3mm and also the parts are within 0.002 mm of the desired specifications.

Therefore, the maximum length of the part can be = 3 + 0.002

and the minimum length of the part can be = 3 - 0.002

Therefore, we can write the inequality as

3 - 0.002 ≤ x ≤ 3 + 0.002

⇒ 3 - 0.002 ≤ x and x ≤ 3 + 0.002

⇒ -0.002 ≤ x-3 and x-3 ≤ 0.002

⇒ 0.002 ≥ -(x-3) and x-3 ≤ 0.002 (Because a > b ⇒ -a<-b)

⇒ 0.002 ≥ | x - 3 |

Step-by-step explanation:

A 22-inch piece of steel is divided into three parts, the length of 1st 2nd and 3rd piece are 3 inch,6 inch and 13 inch.

Given that,

A 22-inch piece of steel is divided into three parts, the second of which is twice as long as the first and the third of which is one inch longer than the first.

We have to find the parts' lengths.

Let us take, the length of the first piece is x inch.

Then the length of the second piece is 2x.

Then the length of the third piece is 4x + 1 inch.

We know total length of the steel is 22 inch.

We can write as,

x + 2x + 4x + 1 = 22

7x = 21

x = 3.

Then, the length of the first piece is 3 inch.

Then the length of the second piece is 2×3=6 inch.

Then the length of the third piece is 4×3 + 1=12+1=13 inch.

Therefore, the length of 1st 2nd and 3rd piece are 3 inch,6inch and 13 inch.

Step-by-step explanation:

You want to write "City A has three times as many people as cities B and C combined" as an equation in standard form, letting x, y, z, w represent the populations of cities A, B, C, D, respectively.

The populations of cites B and C combined can be expressed by ...

  y +z

Three times the combined population is then ...

  3(y +z)

This is equal to the population of city A, so we can write ...
