Answer:I have this same problem but if you’re asking for the independent and other questions here’s the answer. Independent variable is the radio since that’s the only change happening to the 10 other pots. Dependent variable is the height of the plant since that’s what Ramona wants to see change as the output. Control group is the 5 pots without the radio i’m pretty sure. The constants are the amount of seeds, pots, soil, and water.

What is the error in the equation

dimulka [17.4K]

Answer:

The fifth line contains the error.

Step-by-step explanation:

Line 1 is the equation.

Lines 2, 3, and 4 are correct.

The error is in the 5th line.

The square root of a negative number is not a real number, so if this problem is solved only with real numbers, there is no solution.

If imaginary numbers are allowed, then the last line should read:

$x = \pm\dfrac{i\sqrt{11}}{2}$

A+b=95<br> 4a+1.50b=267.5

Papessa [141]

Answer:

a=50
b=45

Step-by-step explanation:

We can subtract the second equation from 4 times the first:

4(a +b) -(4a +1.5b) = 4(95) -(267.5)

2.5b = 112.5 . . . . . simplify

b = 45 . . . . . . . . . . divide by 2.5

a = 95 -b = 50 . . . find 'a'

The solution is (a, b) = (50, 45).
