Answer:
There are 49 white marbles.
Step-by-step explanation:
w + g = 62 (w = white and g = green marbles).
w = 4g - 3
w - 4g = -3 Subtract this equation from the first equation:
g - (-4g) = 62 - (-3)
5g = 65
g = 65/5 = 13.
So w = 62 - 13 = 49.
Answer:
wheres the picture?
Step-by-step explanation:
Amount from dimes would be: 0.1y
Amount from quarters = 0.25x
So, total amount = 0.25x + 0.1y
So, she is not correct
Hope this helps!
Answer:
See attached picture.
Step-by-step explanation:
Find critical points to graph the rational function.
When x = 0, then y = 5 / 2 = 2.5.
When y=0, then 0=-3x+5 and x= 5/3 =1.6667.
Plot the points (0,2.5) and (1.6667, 0). Then draw the "L" shape graphs of the rational function.
