Answer:
12
Step-by-step explanation:
Let the number = x
7x + 1 = 5x + 25 Subtract 5x from both sides.
7x - 5x + 1 = 5x - 5x + 25 Combine
2x + 1 = 25 Subtract 1 from both sides.
2x + 1 - 1 = 25-1 Combine
2x = 24 Divide by 2
2x/2 = 24/2
x = 12
If y is the red marbles and x is the blue marbles, then for every x value you would be able to multiply by 2 to get the y value... it is the equivalent of looking at is as the slope rise/run or 2/1
D is the graph that shows this relationship. Look at the x value and multiply by 2 for the y value.
6.25t + 8 = 12.5t + 13
Subtract 8 from both sides
6.25t = 12.5t +5
Subtract 12.5t from both sides
-6.25t = 5
Divide -6.25 by both sides
t = 0.8
