Answer:
360-(124+124)= 360-248=122 divided by 4=30.5
Percentage ridden = 14/40 x 100 = 35%
Answer: 35%
The answer would be 0.95 totaling 1 as there is only 1 chance that this will happen
To answer this, you can set up a system of equations. Solve for one of the variables and substitute this new equation into the 2nd equation.
2x + 5y = 243 - I'll solve this one for x.
8x + 6y = 538
2x + 5y = 243
2x = 243 - 5y
2 2
x = 121.5 - 2.5y ; substitute this in for x in the second equation
8x + 6y = 538
8 (121.5 - 2.5y) + 6y = 538
972 - 20y + 6y = 538
972 - 14y = 538
-972 -972
-14y = -434
-14 -14
y = 31
<u><em>The cost of a rod (y) is $31. </em></u>
x = 121.5 - 2.5y
x = 121.5 - 2.5 x 31
x = 44
<em><u>The cost of a reel(x) is $44.</u></em>
The constant of proportionality is <em>4 .</em>
The equation is [ <em>Height = (4) times (Days)</em> ] .
When the sunflower is 60cm tall, 60 = (4) times (Days).
Divide each side of the equation by 4: <em>15 = Days</em>
