20-23 red marbles makes the most sense
5/7x + 1/7 = 63
7(5/7x) + 7(1/7) = 7(63)
5/x + 1 = 441
5/x = 440
5 = 440x
5/440 = x
1/88 = x
Answer:
Red Gold
Step-by-step explanation:
Assuming you mean 9/40
Red gold = 25%
Pink Gold = .2 which is 20%
Rose gold is 
= .225 which is 22.5%
Answer:
The second choice is correct
Step-by-step explanation:
Go to a point like 4,3 and 0,1. the difference in x is 4 since 4-0 = 4.
4,3 and 0,1 now we find the change in y, 3-1 which is 2. the formula for slope is change in y over change in x so 2/4 is the slope or 1/2.
The y intercept of the line is 1 since the line touches the y-axis at the y, 1.
therefore the equation is y = 1/2x + 1.
