To solve the problem, we created an equation representing the total cost of 3 T-shirts and a program, and then solved it to find the cost of one T-shirt, which is $25.

Let's denote the cost of one T-shirt as 'T'. Since the total cost of 3 T-shirts and a program is $90, and we know that the cost of the program is $15, we can write our equation as follows: 3T + 15 = 90.

To solve for 'T', we start by subtracting 15 from both sides of the equation, getting us 3T = 90 - 15 = 75.

Next, we would divide both sides by 3 to find the cost of one T-shirt. Hence T = 75 / 3 = $25. So, the cost of one T-shirt is $25.

The length of the square living room is 16 feet.

To find the length of the square living room, we need to calculate the square root of the area.

Given:

Area of the square living room = 256 ft²

Let's denote the length of one side of the square as "s".

The formula for the area of a square is:

Area = side length x side length

256 = s x s

256 = s²

To find the length of the room (s), we take the square root of 256:

s = √256

s = 16

Therefore, the length of the square living room is 16 feet.

The probable question may be:

The area of a square living room is 256 ft^2. Which is the length of the room?

The value of the given expression 2x{6+[12 divided by (3+1)]}-1 is 17 when following the order of operations.

To solve the mathematical expression 2x{6+[12 divided by (3+1)]}-1, the first thing you have to do is follow the order of operations, which is abbreviated as PEMDAS (Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right)).

Step 1: Solve the operation within parentheses, 12 ÷ (3+1) = 12 ÷ 4 = 3.

Step 2: Subtitute the result back into the equation, 2x{6+[3]}-1.

Step 3: Solve the operation within brackets, {6+[3]} = {9}.

Step 4: Substitute the result back into the equation, 2x{9}-1 = 2x9 - 1 = 18 -1 = 17.

Cole have 45 minutes of free time and he play the guitar for 30 minutes. That is 2/3 of free time.

Because the number of minutes in an hour is fixed at 60, you can divide any number of minutes by 60 to get a fraction of an hour. For example, 10 minutes equals 10/60 = 1/6 hour, and 24 minutes equals 24/60 = 6/15 hour.

For example, 375 minutes divided by 60 equals 6.25 hours. Multiply that fraction of an hour by 60 to get it back to minutes. In this case,. 25 x 60 = 15, implying that 375 minutes equals 6 hours and 15 minutes.

Although numbers such as 1/6 and 6/15 of an hour are accurate, they are not always easy to compare to other time measurements.

1 hour = 60 minutes meaning 1 whole,

3/4 of an hour = 45 minutes

so 2/3 of 45 minutes = 30 minutes

15+15+15= 45

so 15 + 15 = 30 minutes

He play the guitar for 30 minutes

The inequality represent the given situation is 200-15d<80.

Inequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.

Given that, a scrapyard had 200 tons of recycled steel.

They sold 15 tons per day for several days.

Let the number of days be d.

Here, the inequality is 200-15d<80

Add 15d on both the sides of an inequality, we get

200-15d+15d<80+15d

200<80+15d

Subtract 80 on both the sides of an inequality, we get

120<15d

Divide 15 on both the sides of an inequality, we get

d>8

Therefore, the inequality represent the given situation is 200-15d<80.

An angle that turns through one-twelfth of a circle measures 30 degrees.

The measure of an angle that turns through one-twelfth (1/12) of a circle is 30 degrees. A full turn of a circle is 360 degrees, so if we divide that by 12, we get the angle of a single twelfth of a turn. Mathematically, this is calculated as 360 degrees / 12 = 30 degrees. In other terms such as radians, this angle can be calculated as 2π radians (which represents a full turn) divided by 12, giving us π/6 radians, but for middle school mathematics, measuring in degrees is more common.

The system of linear equations is solved by substitution, resulting in the solution x=-3/5 and y=6.2.

To solve the system of linear equations by substitution, start with the given system:

4x − 2y = 14
y = 12x − 1

Since y is already isolated in the second equation, substitute (12x − 1) for y in the first equation:

Now substitute x = −3/5 into the second equation to find y:

The solution for the system of equations is x = −3/5, y = 6.2.

The second cabinet has a greater volume of 63 cubic feet compared to the first cabinet's volume of 37.5 cubic feet.

To compare the volume of the two cabinets, we will calculate the volume for each by multiplying the length, width, and height.

For the first cabinet, the volume is 3 feet x 2.5 feet x 5 feet, which is 37.5 cubic feet.

3 feet x 2.5 feet x 5 feet = 37.5 cubic feet

The second cabinet has a volume of 4 feet x 3.5 feet x 4.5 feet, which equals 63 cubic feet.

4 feet x 3.5 feet x 4.5 feet = 63 cubic feet

Therefore, the second cabinet has a greater volume than the first.
