I assume we're solving for n.
3n/7 - 1 = 1/8.
First, add 1 to both sides.
3n/7 = 9/8
Now, let's multiply both sides by 7
3n = 63/8
Divide both sides by 3
n = 21/8
Determine what kind of solution you would expect from the system of equations 3x - 8y = 10 and 16x - 32y = 75 without graphing the system. Explain how you determined your answer.
Step-by-step explanation:
If two lines have the same slope and the same y-intercept, there are infinite solutions.
If two lines have the same slope and different y-intercepts, there are zero solutions.
Otherwise, if the two lines have different slopes, then there is one solution.
The slope of the first line is 3/8. The slope of the second line is 16/32 = 1/2. The slopes are different, so there is only one solution.
The solution of the given system of equations is (x, y) = (8.75, 2).
What is a Linear equation of two variables?These are the system of equations with two variables having a no solution, unique solution or infinitely many solutions.The highest order of the equation for this systems is one.Given: System of equations
3x - 8y = 10 …(1)
16x - 32y = 75 …(2)
Consider equation (2).
⇒ 16x - 32y = 75
Dividing both sides by 16, we get:
⇒ x - 2y = 75/16
⇒ x = 2y + 75/16 …(3)
Now, substitute the value of x = 2y + 75/16 in equation (1), we get:
⇒ 3(2y + 75/16) - 8y = 10
⇒ 6y + 225/16 - 8y = 10
⇒ 2y = 225/16 - 10
⇒ 2y = (225 - 160)/16
⇒ 2y = 65/16
⇒ y = 65/32
⇒ y ≈ 2
Now, put the value of y = 65/32 in equation (3), we get:
⇒ x = 2(65/32) + 75/16
⇒ x = (65/16) + (75/16)
⇒ x = 140/16
⇒ x = 8.75
Therefore, the solution for the given simultaneous equation is;
(x, y) = (8.75, 2)

Your friend, Jamie, rolled a number cube and got the number 5. On his next turn, he says he won’t be able to roll another 5 because he is only expected to roll a 5 once every six rolls. Is your friend correct? Explain your answer.
Answer:
No
Step-by-step explanation:
Even though he has a 1/6 chance of rolling it he still has a 16.67% percent chance
Answer:

does a function have to be linear
Answer:
Hi there
Step-by-step explanation:
A linear function is a type of function and so must follow certain rules to be classified as a “function”. For example, functions can only have one output for each input. On the other hand, equations are just statements that make two things equal, like x = y or 52x = 100.

Answer:
x= - 13
Step-by-step explanation:
2(3x+6) = 3(x-9)
6x+12 = 3x -27
-3x -3x
3x+12=-27
-12 -12
3x= -39
/3 /3
x= - 13
Answer:
x = -13
Step-by-step explanation:
2(3x + 6) = 3( x - 9)
Distribute
6x +12 = 3x - 27
Subtract 3x from each side
6x-3x+12 = 3x-27-3x
3x+12 = -27
Subtract 12 from each side
3x+12-12 = -27-12
3x = -39
Divide by 3
3x/3 = -39/3
x = -13

A chef turned on a faucet and filled a 2-gallon pot in 5 6 of a minute. What is the rate of water flow? Simplify your answer and write it as a proper fraction, mixed number, or whole number.
Answer: Rate of water flow is 12/5 gallon per minute
Step-by-step explanation:
Given the following :
Volume of faucet pot = 2 gallon
Time taken to fill the faucet pot = 5/6 of a minute = (5/6) minute.
Rate of water flow:
Volume of faucet pot / time taken
= 2 gallon ÷ (5/6) minute
= 2 gallon × (6/5) minutes
= (12 /5) gallon / minute
= 2 2/5 gallon / minute
Hence rate of water flow is 12/5 gallon per minute.

explain how 5x-3y=2 and 5x-3y=8 are parallel without doing any calculations
Answer:
They're parallel because the first part of the equations have the same numbers/variables (can see down below in bold). This tells us whether or not it's parallel. There's no need for any calculations due to this.
5x - 2y = 2
and
5x - 2y = 8
The answer of the equations doesn't affect it, only is they're the same number. Then it becomes overlap.
For Example:
5x - 2y = 9
and
5x - 2y = 9
they're the same, meaning overlap.
