Subtract the two Y values of X = 2 and X = 4 to find the total difference, then divide by the difference between X=2 and X =4
When X = 2 Y = 9
When X = 4 Y = 64
Difference between the two Y values = 64 -9 = 55
Difference between the two X values = 4-2 = 2
The rate of change = difference in Y divided by difference in X:
55/2 = 27.5
In the example given, we see there are 14 trout out of 50 fish. This can be written as 14/50. You then make the bottom number equal 7500, and multiply the top number by the same amount to get the answer. In this case, 7500 ÷ 50 = 150. So then we just do 14 × 150 = 700, and 700 is your answer. Hope this helped!
Answer:
2.50x+7.00=10.00+4.00x
Step-by-step explanation:
The time it will take for Tyler to finish planting tomatoes alone is; 75 minutes
<h3>
Understanding Work Proportion</h3>
We are told that three people are planting tomatoes in a community garden. The time each alone takes to plant are;
Thus, their individual rates are;
Since together, they take 20 minutes, then it means that;
1/50 + 1/x + 1/(x + 15) = 1/20
Multiply through by x(x + 15) to get;
(x² + 15x)/50 + (x + 15) + x = (x² + 15x)/20
Multiply through by 100 to get;
2(x² + 15x) + 100(x + 15) + 100x = 5(x² + 15x)
100x + 1500 + 100x = 5(x² + 15x) - 2(x² + 15x)
200x + 1600 = 3x² + 45x
3x² - 155x - 1600 = 0
Solving this using quadratic formula calculator online gives;
x ≈ 60
Thus, the time it will take tyler alone to finish is;
60 + 15 = 75 minutes
