2 minutes of time both the tanks have same amount of water and total amount of water at that minute will be 25 gallons.

Two or more expressions with an Equal sign is called as Equation.

The amount of water in Jason's dunk tank is represented by the equation below, where W represents the amount of water, in gallons, x minutes after he began to fill.

w=2x+1

The amount of water in Mark's dunk tank is represented by the equation

w=10x+5

The total amount of water in both dunk tanks will be the same.

2x+1=10x+5

8x=-4

Divide both sides by 4

x=-2

So at 2 minutes of time both the tanks have same amount of water.

Now plug in 2 value in any of equation

W=25

Hence, at 2 minutes of time both the tanks have same amount of water and total amount of water at that minute will be 25 gallons.

Answer:

  ∆ABC is an isosceles triangle

Step-by-step explanation:

You have a triangle ABC such that the angle bisector of angle B also bisects side AC.

An angle bisector divides the sides of the triangle proportionally. This means the sides BA and BC will have the same ratio as the segments of AC on either side of the point of intersection with the angle bisector.

Since AC is bisected, that means those segments are congruent, hence sides BA and BC are congruent. The triangle is isosceles.

The value of the equations are

A =  0.93 x 2.6 = 2.418

B = 93 x 0.26 = 24.18

C = 9.3 x 26 = 241.8

D = 0.93 x 0.26 = 0.2418

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Elisa was charged a basic interest rate of 120% per year by the pawnbroker since she needed the money to fix her house air conditioner.

By dividing the initial by the interest income, the aging process, and other factors, simple interest is determined. Simple yield equals principal plus interest full days is the concept used in marketing. The easiest thing to compute interest is to employ this method. The most frequent method for calculating it is as a portion of the outstanding sum. For example, if he takes $100 from a buddy and undertakes to return the loan at 5% interest, he will only spend his share of the 100% interest. $100 (0.05) = $5. When you borrow money, you must make payments, and you must pay the interest whenever you lend it. Typically, interest is computed as an indicator of the overall of the loan total. The loan's interest is the name given to this percentage.

given

I = PRT/100

Simple interest (I) is calculated as follows: amount - principal ($279.90 - $270) = $9.90

P (principal) is the $270 loan made to Elisa.

R is the interest rate on a yearly basis.

The loan's amortisation period, or T (time), is 11 days, or 11/360 years.

9.9 = 270 × R × 11/360 × 1/100

R = (9.9×360×100)/(270×11) = 120%

120% is the annual simple interest rate.

Answer: The number of solutions for the system of linear equations depends on whether the lines are parallel or intersect at a single point. If the lines are parallel, there are no solutions, as they never meet. If the lines intersect at a single point, there is exactly one solution.

To determine the number of solutions, we need to find the point of intersection of the two lines. We can do this by solving for x in one equation and substituting it into the other equation:

2x + 3 = 8/4 x - 1/4

8x + 12 = 2x - 1/2

6x = - 12.5

x = -2.08

Then, substituting this value of x back into either equation to find the corresponding value of y:

y = 2 * (-2.08) + 3 = 0.16

So, the two lines intersect at the point (-2.08, 0.16), which means there is exactly one solution to the system of linear equations.

A interaction between two terms or concepts that is neither equal in mathematics is referred to as an inequality. Consequently, inequity results from imbalance. In algebra, an inequality establishes the connection between two non-equal numbers. Egality and inequalities are not the same. Use the not comparable symbol most usually when two components are really not equal (). Values of any size can be contrasted using a variety of inequalities. By changing the two aspects until only the variables are left, many straightforward inequalities can be solved. But, a variety of factors support inequality: Both sides' 0 are split or added.

-22 < 7x is the inequality that is equivalent to the given inequality.

What is inequality?

An inequality is a relation that compares two numbers or other mathematical expressions in an unequal way. The majority of the time, size comparisons between two numbers on the number line are made. Different types of inequalities are represented by a variety of notations, including:

The symbol a < b indicates that an is smaller than b.

When a > b is used, it indicates that an is bigger than b.

Here, we have

Given: -4(x + 7) < 3(x - 2)

To find out which inequality is equivalent, you solve for x.

-4(x+7) < 3(x-2): distribute variables

-4x-28 < 3x-6: Add 6 to both sided

-4x-22 < 3x: add 4x to both sides

Answer:

Step-by-step explanation:The equation for the nth term of an arithmetic sequence is given by:

an = a1 + (n-1)d

Where:

a1 is the first term of the sequence

d is the common difference

n is the number of the term we want to find

Using the given information, we have:

a1 = -9 and d = 2

Plugging these values into the formula, we get:

an = -9 + (n-1)2

To find the 12th term of the sequence:

n = 12

an = -9 + (12-1)2

an = -9 + 11 * 2

an = -9 + 22

an = 13

So the 12th term of the sequence is 13.

The required final balance on interest rate of 6%per annul is  $354.

The fee you pay to borrow money or the fee you charge to lend money is called interest. The most common way to represent interest is as a yearly percentage of the loan amount. The interest rate on the loan is known as this percentage.

Simple interest is calculated as:

I = P * r * t

where I is the interest, P is the principal (initial investment), r is the annual interest rate as a decimal, and t is the number of years.

So, in this case:

I = 300 * 0.06 * 3

I = 300 * 0.06 * 3 = 54

The final balance would be the sum of the initial investment and the interest earned:

Final balance = P + I

Final balance = 300 + 54

Final balance = 300 + 54 = 354

Rounded to the nearest cent, the final balance is $354.
