Answer:
The simple interest is $300.
Step-by-step explanation:
<em>Find the Interest amount.</em>
I: Interest ?
P: Principle Amount $2500
R: Rate 6% = .06
T: Time Period (in years) 2 Years
<em>Convert into equation to find Simple Interest</em>
I = Prt
I = (2500)(.06)(2)
<em>Calculate</em>
I = 300

A. 38
Let X = seventh graders
6th graders are twice the number of 7th graders; therefore, 6th graders will be 2X.
The total number of students is 57.
2X + X = 57
3X = 57
X = 57 / 3
X = 19
IF X represents the 7th graders; there are 19 seventh graders present.
Since 6th graders are represented by 2X; Then, 2 * 19 = 38 is the number of 6th graders present.
Add both numbers to check: 19 + 38 = 57.
The volume of this prism would be 294 cubic units.
To determine this you can use the given perimeter of 28 to create combinations of dimensions of a recatangule prism.
I started with 7 + 7 + 7 + 7 to get 28. This means the length and width were both 7 units.
This would make the dimensions of this prism 7 x 7 x 6(the height).
The find the volume multiply all three numbers.
The volume is 296 cubic units.
The pair has one solution.
Answer: Option B.
<u>Explanation:</u>
A system of two linear equations can have one solution, an infinite number of solutions, or no solution. Systems of equations can be classified by the number of solutions. If a system has at least one solution, it is said to be consistent . If a consistent system has exactly one solution, it is independent.
If the system in two variables has one solution, it is an ordered pair that is a solution to both equations. In other words, when you plug in the values of the ordered pair it makes both equations TRUE.
