Water is leaking from a tank. After t minutes, the volume of the water in the tank is 16(200-9t) milliliters. What is the volume of water left in the tank after 18 minuets?

To solve the equation -3x = 15, you divide by -3 to get x = -5. To check, substitute -5 for x in the original equation to verify that the left and right sides are equal.

To solve the equation -3x = 15, we want to isolate x on one side of the equation. The algebraic property we will use here is the Division Property of Equality, which states that if we divide both sides of an equation by the same nonzero number, the two sides remain equal.

Step-by-Step Solution:

Now, let's check the answer to verify it's reasonable. Substitute x = -5 back into the original equation (-3x = 15) and see if the equation holds true:

The value of the variable t is greater than or equal to 3.

The analysis of mathematical representations is algebra, and the handling of those symbols is logic.

PEMDAS rule means for the Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This rule is used to solve the equation in a proper and correct manner.

Fifteen is no more than a number t divided by 5 will be given in the mathematical form. Then the inequality is given as,

15 ≤ 5t

t ≥ 15 / 5

t ≥ 3

The value of the variable t is greater than or equal to 3.

A line is a straight, infinite, one-dimensional entity with no thickness or endpoints. It can be represented mathematically, intersects at points or can be parallel to other lines.

Given that,

To find the characteristic of a line.

Now, A line is a fundamental geometric concept characterized by several key properties.

Firstly, it is straight and extends infinitely in both directions.

Secondly, it has no thickness, meaning it is one-dimensional and can be represented by a mathematical equation or equation system.

Thirdly, any two points on a line can be connected to form a segment, making it possible to measure distances along the line.

Now, Additionally, a line has no endpoints, which distinguishes it from a line segment.

Lastly, lines can intersect each other at a single point or be parallel, maintaining a constant distance from one another throughout their lengths.

The constant rate of change of $8 per hour signifies that for each hour that passes, the associated value increases by $8. To find missing values in the table, you add or subtract $8 per hour depending on whether you're looking forward or backward in time.

Since the constant rate of change in your table is $8 per hour, this means that for each hour that passes, the value in your relationship increases by $8. This value is akin to the concept of constant slope in the graph of a linear function, where the 'rise over run' (or change in y-values over change in x-values) remains the same.

To find the missing values in your table, start with the first known value and add $8 for each subsequent hour. If you're moving backwards (i.e., from a time later to an earlier time), you would subtract $8 for each hour.

For example, if you know that the value at 2 hours is $20, then the value at 3 hours would be $20 + $8 = $28. On the other hand, the value at 1 hour would be $20 - $8 = $12.

By applying this step-by-step process, you should be able to fill in the missing values in your table.

To find the total cost of shipping a 7-pound care package, you can use the formula: Total Cost = (Cost per pound * Number of pounds) + Flat fee. When applying this formula to the given scenario, the total cost to ship a 7-pound care package is $17.95.

To find the total cost of shipping a 7-pound care package, consider that it costs $0.85 per pound plus a flat fee of $12. You can create an algebraic expression to find the total cost:

Total Cost = (Cost per pound * Number of pounds) + Flat fee

Substitute in the values: Total Cost = ($0.85 * 7) + $12 = $5.95 + $12 = $17.95

sqrt(60) =7.745967 rounded to nearest 100th = 7.75

58/8 = 7.25

7.3 rounded to nearest 100th = 7.33

7 3/5 = 7.6

7.6 +7.33 +7.25+7.75 = 29.93/4 = 7.4825 = 7.48km

The value of x is 32.

An equation is a mathematical statement that is made up of two expressions connected by an equal sign.

Example:

2x + 3 = 9 is an equation.

We have,

x/8 + 12 = 16

Solve for x.

x/8 + 12 = 16
Subtract 12 on both sides.

x/8 = 16 - 12

x/8 = 4

Multiply 8 on both sides.

x = 8 x 4

x = 32

Thus,

The value of x is 32.

One bag of sugar can make 19 batches of chocolate chip cookies.

To determine how many batches of chocolate chip cookies can be made with one bag of sugar, we need to divide the total amount of sugar in the bag by the amount of sugar used in each batch of cookies. Since the bag holds 23 3/4 cups of sugar, and the recipe uses 1 1/4 cups of sugar per batch, we can set up the following division:

23 3/4 ÷ 1 1/4 = (95/4) ÷ (5/4) = (95/4) × (4/5) = 95/5 = 19

Therefore, one bag of sugar can make 19 batches of chocolate chip cookies.
