Well if you add them all together you would get 25. You would have 9/25 red marbles. Then you would take 9 and divide it by 25 and get 0.36 and if you move the decimal over 2 places you’ll get 36%
For this problem I would change:
2x + 3y = 25 into
-2x - 3y = -25
Then, I would add up both equations by lining them up top of another.
5x + 3y = 31
+ -2x - 3y = -25
3x = 6
x = 2
Now that you have x, solve for y.
5x + 3y = 31
5(2) + 3y = 31
10 + 3y = 31
3y = 21
y = 7
So, x is 2 and y is 7.
Check to see if the values are correct by plugging them into the other equation.
2x + 3y = 25
2(2) + 3(7) = 25
4 + 21 = 25
25 = 25
Since the values are correct, the solution to this problem is A (2, 7).

Answer:
we can say that You drive 43.79 km
Step-by-step explanation:
Distance covered for drive to school = 24.84 km
Distance covered for drive to friends = 18.95 km
We need to find how far do you drive.
It means we need to find the total distance covered
<em>Total Distance Covered = Distance covered for drive to school + Distance covered for drive to friends</em>
Putting values and finding total distance
<em>Total Distance Covered = Distance covered for drive to school + Distance covered for drive to friends</em>
<em>Total Distance Covered = 24.84 + 18.95</em>
<em>Total Distance Covered = 43.79</em>
So, the total distance covered by you during driving is: 43.79 km
Therefore we can say that You drive 43.79 km
Q1 shows the position of the first 25% of the data set. Since Q1 = 110, 25% of the electricians had a score of 110 or less.
