Answer: 59 & 21
Step-by-step explanation:
so this probably won't be the best explanation, but here goes:
For the sake of knowing the two numbers aren't equal to each other, I decided to do variables n and x, so:
n+x=80
Now we need to find the value of n:
So the question sets this up as
n-2x=17. We need to change the equation so that we're solving for n, so: n=17+2x
Next we need to solve n+x=80, to do that we need to make it into x=80-n
Now that they're set up like this we can do : 80-n=17+2x.
I honestly don't know how to explain it the rest of the way but if you plug in those two numbers they should be right.
Answer:
Step-by-step explanation:
Since the time for the pot of water to boil is inversely proportional to the cooker setting, H, as one goes up, the other must go down:
Convert 5 minutes to seconds:
Therefore, from the initial data given (When H=6, T=90), the new time is larger. Therefore, H must be times <em>smaller </em>for them to be inversely proportional.
Answer:
Your answer is: (-1/2, 3/2)
Step-by-step explanation:
y = x + 2
y = -3x
Use substitution by plugging the second equation into the first.
-3x = x +2
Subtract x from both sides to combine the variables.
-4x = 2
Divide both sides by -4 to isolate the variable x.
x = 2/-4
Simplify.
x = -1/2
Plug x into one of the equations to find y.
y = (-1/2) + 2
y = 3/2
Plug x into the other equation to confirm your answer.
y = -3(-1/2)
y = 3/2
Your answer is: (-1/2, 3/2)
