If there are 36 potato plants, and they are in 4 even rows, that means that there is 9 in each column because 9 x 4 is 36. Since 7 of them were eaten by the sheep and the goat, that means that there are 2 leftover in that row that the sheep and goat got to since 9-7 is 2.
Could you attach an illustration? I apologise.
The slope of the first equation is -2, you can see it right off.
the slope of the second equation is 2, notice both are in slope-intercept form.
both equations are the equations of a line, so is really just two lines.
because their slope differs, they're not parallel or equivalent, therefore, they lines do meet at some point, and one point only, and therefore, they have 1 solution only.
a system of equations with at least 1 solution, is a consistent system.
a consistent system with exactly 1 solution only, is not just consistent, but also independent.
150,000 = 50000a^20
a^20 = 150000/50000 = 3
a = 20th root of 3 = 1.056467
Required equation is P = 50000(1.056467)^t
Answer:
72 green marbles
Step-by-step explanation:
45 divided by 5 is 9 so 8 times 9 is 72
