It’s 3/6 but you simplify it to 1/2
1/2 is ur answer :)
2ˣ = 2³
Since 2ˣ is EQUAL to 2³ and since 2 is equal to 2, then the solution is a must that the 2 exponents are equal.
Then x = 3
Answer: the system of equations are
x + y = 35
3x + 2y = 100
Step-by-step explanation:
Let x= the number of short answer questions.
Let y= the number of multiple choice questions.
Noah wants 35 questions on the exam. This means that
x + y = 35
He plans to mix short answer questions, worth 3 points, with multiple choice questions worth 2 points. This means that x short answer questions will give 3x points and y multiple choice questions will give 2y points
Since the exam is worth 100 points, then,
3x + 2y = 100 - - - - - - - -1
Substituting x = 35 - y into equation 1, it becomes
3(35 - y) + 2y = 100
105 - 3y + 2y = 100
y = 105 - 100 = 5
x = 35 - y = 35 - 5
x = 30
Answer:
314.16
Step-by-step explanation:
pi times radius squared is your formula, so plug it into your calculator just like that. 10^2*pi
