Answer:
20 days
Step-by-step explanation:
2212 divided by 114 =19.40350877, so round it up to the nearest tenth, which is 20. he has read for 20 days
the math behind it:
your equation looks like this: .25x = 10
then you divide both sides by .25 and then ur equation looks like this: x=40
by the way the variable x stands for the number you are looking for. and since x=40, the number you are looking for is 40
well i hope i helped!
Answer:
you can go on a maximum of 11 rides
Step-by-step explanation:
you first have to subtract 30 from 100 since that is the admissons fee.
So now you are left with 70 dollars.
You divide 70 by 6 since you need 6 dollars to go on each ride.
and 70 divided by 6 is 11.6666666667 but round it to 11 since that the whole number you're left with.
hope this helped :)
Answer: C is correct, No solution
Step-by-step explanation:
Let’s simplify the second equation,
8x-4y=-20
We can divide the whole equation by 4...
8x/4-4y/4=-20/4
Which becomes....
2x-y=-5
Now let’s move things around to see if it’s the same equation as the one on top...
-y=-2x-5
y=2x+5
Now we need to solve the systems...
y=2x-5
y=2x+5
Since their slopes are both 2 and their y-intercepts are not identical, the answer is no solution. The two lines will continue on without ever crossing because they have the same slope.
