Answer:
We have the following given
mileage = 70 miles per gallon
distance = 60 km
Required: amount of fuel in gallons
First, we must convert the distance to miles, so
60 km (1 mi/1.6 km) = 37.5 mi
So, the amount of fuel is
37.5 mi / (70 mi/gal) = 0.54 gallon
Answer:
6/6
Step-by-step explanation:
6/6 not equal -1/1 so these lines intersect each other at only one point hence these have only one solution.
Answer/Step-by-step explanation:
1. -14
2. 3
3. -3
4. 10
5. -8
1. 4 x -3 = -12 - 2 = 14
2. -3 x 2 = -6 + 9 = 3
3. 8 divided by 4 = 2 - 5 = -3
4. 3/2 = 1.5 x 2 = 3 + 7 = 10
5. -9/3 = -3 - 5 = -8
Answer:
X-intercept = -3 and y-intercept = 6
Step-by-step explanation:
We can start off by isolating the y term. To do that, we must add 2y to both sides to get
Now, we must add 12 to both sides and the y term will be all alone on the right side:
Now, to have only y on the right side, we must divide by 2 to get:
In slope-intercept form, b is the y-intercept, and 'b' in this equation is 6. We have our y-intercept.
To find our x-intercept, y must be equal to zero. We can plug in that value for y and solve for x:
We can start off by subtracting 6 from both sides to get:
We can then divide both sides to get 
when y is equal to 0. Thus, we have our x-intercept.
I'm going to assume that the table looks like this:
Plants: 15 | 20
Fish: 6 | 8
If this is what it looks like, then the equation is:
2F=5P, or F=2.5P
When you have 3 plants, then you can substitute and solve:
2F=5P --> 2F=5(3) --Substitute
2F=5(3) --> 2F=15 --Multiply
2F=15 --> F=7.5 --Divide
The mathematical answer says 7.5 fish, but this answer might
be incorrect because we can clearly see that there are more plants than fish.
So, another method that you could use is to fill in the table:
Plants: 0 | 5 | 10 |15 | 20
Fish: 0 | 2 | 4 | 6 | 8
We can see from the table that when there are 0 plants, there are 0 fish,
and when there are 5 plants, there are 2 fish. We know that 3 is 3/5 of 5,
so we can use this ration to find 3/5 of 2, to find the number of fish in the
tank when there are 3 plants.
3/5 of 2 ends up being 1.2, but it's impossible to have 1.2 fishes (yes,
fishes is indeed a word), so you should round down to the nearest whole
fish.
The answer is 1.
