The system of equations would be x + y = 28 and 3x + 5y = 100.
<h3>What is a system of equations?</h3>
A system of equations is two or more equations that can be solved to get a unique solution. the power of the equation must be in one degree.
Given;
A test is worth 100 points. Multiple-choice questions are worth 3 points and short-answer questions are worth 5 points.
If the test has 28 questions
Let x be multiple-choice questions
Let y be short-answer questions
The system of equations would be
x + y = 28
3x + 5y = 100

We know that:
perimeter = (2 x width) + (2 x length)
Plugging in what we know to this equation:
40 = (2 x 8) + (2 x length)
40 = 16 <span>+ (2 x length)
</span>24 = <span>2 x length
</span>12 = length
The length of the room is 12 feet
Step-by-step explanation:
Head(H) Tails(T)
Sample space is S (HHH,HHT,HTH,THH)
Event(HHT,HTH,THH)
so the probability is 3/4
