Answer:
Step-by-step explanation:
5 red
15 black
10 white
altogether the is 30 marbles so that means it is 'out of' 30
and because the is 5 red it would be 5/30
and because the is 10 white it would be 10/30
that should be the answer but if you have to work the total all together then it would be 15/30
hope this helps :)
Answer:
There is no solution of the system of equations.
Step-by-step explanation:
We are given two equations y = - 4 and y = 4 and are to find the solution to the equations.
Now, the straight line y = - 4 is parallel to the x-axis as the equation of straight lines that are parallel to the x-axis are given by y = c, where c is any constant value.
Again, the straight line y = 4 is parallel to the x-axis.
Therefore, y = - 4 and y = 4 two lines are parallel to each other and we know, parallel lines never intersect and hence there is no solution of the system of equations. (Answer)
While you cannot solve 946x+642y=911 for numerical values of x and y, you can indeed solve 946x+642y=911 first for x and then for y:
-911 - 642y
For x: 946x+642y=911 becomes 946x = 911 - 642y, or x = ------------------
946
911-946x
For y: 946x+642y=911 becomes 642y = 911-946x, or y = ---------------
642
Answer:
1) u > 4
2) 7 < u
3) u < 4
4) 7 > u
Step-by-step explanation:
1) subtract 6 - 2
2) add 3 + 4
3) subtract 4 on both sides (8-4)
4) subtract 9 - 2
