Complete Question
Kelvin finished 2/3 of his test in a 1/2 hour. Express this rate in hours per test.
Answer:
3/4 hours per test
Step-by-step explanation:
2/3 of his test = 1/2 hour
This rate in hours per test is calculated as:
x = 1/2 /2/3
x = 1/2 hour ÷ 2/3 test
x = 1/2 × 3/2
x = 3/4 hours per test
This rate in hours per test is given as 3/4 hours per test
Answer:
Addition and Subtracttion
Step-by-step explanation:
The order of operations has to with a generally accepted order to follow when evaluating a mathematical expression.
PEDMAS or BODMAS is the order of operations to follow.
The two operations that are on the same level within the order of operations are addition and subtracttion
This means that, neither has a preference over the other.
After factoring
the solutions are x=0 , x=3, x= -3
Step-by-step explanation:
We need to solve by factoring:

Solving:

Taking 3x common:

Now using formula 


So, After factoring
the solutions are x=0 , x=3, x= -3

So, we know the sum of the first 17 terms is -170, thus S₁₇ = -170, and we also know the first term is 2, well

well, since the 17th term is that much, let's check what "d" is then anyway,
