Answer:
Step-by-step explanation:
The letter "x" is often used in algebra to mean a value that is not yet known. It is called a "variable" or sometimes an "unknown". In x + 2 = 7, x is a variable, but we can work out its value if we try!

Answer:
<h2>A) Population A has a high water potential and loss due to transpiration because of the increased humidity.</h2>
Step-by-step explanation:
Notice that the hypothesis is that relative humidity affects the transpiration of the body. So, in order to prove such hypothesis, we need to find enough evidence about water loss due to higher humidity. Knowing the relative humidity as the relation between water vapor and the pressure of it.
Therefore, the right answer is A, because we need to prove that a high water potential and loss due to transpitation happens because of the increased humidity.
Answer:
Step-by-step explanation:
(2x^2-x)+(x^2+3x-1)
2x^2-x+x^2+3x-1
x^2+3x-1
5x^2+2x-1+(4x^2-x+2)
5x^2+2x-1+4x^2+x-2
9x^2+6x-3
(3x^2+2x+1)+(x^2-1)
3x^2+2x+1+x^2-1
4x^2+2x
-x^2-1+(4x^2-x)
-x^2-1+4x^2-x
3x^2-1-x
Answer:
x + y = 24
16x + 20y = 434
x = 11.5
y = 12.5
Step-by-step explanation:
Part A:
x + y = 24
16x + 20y = 434
Part B:
simplify the second equation to find a "kind of answer" to a variable,
so we could simplify it to either y = 21.7 - 0.8x or x = 27.125 - 1.25y
in this case we will use y = 21.7 - 0.8x
substitute your new value of y into the first equation:
x + (21.7 - 0.8x) = 24
now, we can solve this to find the actual value of x: x = 11.5
so plug in your real x value to the simplified second equation (y = 21.7 - 0.8x)
you get y = 12.5
