I think it's D hope you get it right
40% of the jerseys are medium sized,
That is because to find the percentage do,
20/50 = 0.40
This shows that 40% of the jerseys are medium
You can also do this:
20 to 50 (Ratio of medium to total jersey)
Multiply by 2 to both sides to get 100 for the total jerseys,
40 to 100
This also shows that 40% of the jerseys are medium sized
Answer:y=3x+14
Step-by-step explanation:
<span>ets say in this case x is the amount or rainfall in inches on a given day. We imagine that the ground around the lake absorbs some amount of rainfall. When rainfall is less than this the lake level does not go up. Lets say that rainfall level is 1 inch so we want the polynomial to equal zero for x = 1 and to increase after that.
The polynomial y (water level) = (x-1)(x+1) has a solution y = 0 at x = 1 and is an upward facing parabola so that as x increases so does y. negative values of rainfall have no meaning so we are interested only in the polynomial when x is GT zero.
x=0 y=-1 lake level drops one inch a day without rain
x=1 y=0 one inch of rain and water level stays constant
x=2 y = 3 two inches of rain and water level goes up 3 inches</span>
Let the number of baskets be x
Let the number of points be y
32 +3x = y
19 + 4x = y
Rearrange both equations then solve them as simultaneous equations
32 = y - 3x
19 = y - 4x
y - 3x = 32
- y - 4x = 19
x = 13
Substitute x into one of the equations
y - 3x = 32
y - (3 x 13) = 32
y - 39 = 32
y = 32 + 39
y = 71
Number of baskets (x) = 13
Number of points (y) = 71
