There were 16 oat meal
40 divided 5/3 = 24
40-24 = 16
Hope this helps!
Answer:
5x+40
Step-by-step explanation:
You would distribute 5 to x+8 and that would add up to 5x+40.
Answer:
Step-by-step explanation:
If the liquid is cooling at a constant rate, then the equation for this is linear. We can use the info given to find the linear equation for this situation. We have 2 points: (2, 178) and (5, 154), where the x coordinate represents the time in minutes, and y represents the temperature. We use these values in the slope formula:
Now we will use one of the points to finish writing the equation. I chose (2, 178), but it doesn't matter which one you choose; they will both give you the same equation in the end.
y - 178 = -8(x - 2) and
y - 178 = -8x + 16 so
y = -8x + 196
If we are looking for the temp when the liquid starting cooling, then we are looking for the temp at time 0, or when x = 0 (sincce x is our time).
y = -8(0) + 196 so
y = 196
That's the temp of the liquid before it started any cooling.
Answer:
3/4
Step-by-step explanation:
Let's break it down
1 1/2 is a mixed number
How do we find the fraction form of mixed numbers?
We multiply the denomiator of the fraction part with the integer part and add the current number on the numerator to get your new numerator. The denomiator stays the same.
So in the case of 1 1/2, our new numerator is 2 x 1 + 1 = 3.
Thus, the fraction version is 3/2. Now we need to mulitply this by 1/2
3/2 x 1/2. We just have to multiply the numerator and demoniator
3 x 1 is our numerator
2 x 2 is our denomiator
3/4 cannot be simplified because the numerator and denomiator are both relatively prime (numerator is not divisible by denomiator and vice versa)
