She can color 1/20 of a square in one second, so 1/20*40=2. Hope this helps, and Brainliest answer would be appreciated!
The answer to the question is the second and the fourth equations
95% of
20 is 19
Convert your percentage into a decimal:
Divide 19 by your decimal:
Use the equation .8x + x = 252
x is the number, and .8 is the decimal equivalent of 80%.
1.8x = 252
x = 140
1. ratio = 2 c of dressing / 4 lb of vegetables
Use two variables: d for the number of c of dressing and v for the number of pounds of vegetables.
Then d / v = 2/4 = 1/2 => d = v/2
Now you can make a table
v d
2 1
4 2
6 3
8 2
And you can draw a line for the points (2,1); (4,2); (6,3), (8,4) ... the slope of the graph is the ratio = 1/2
b) I already did it above as part ot the explanation: d/v = 1/2
