Answer:
x = 9/25, y = 7/25, z = 4/25
Explanation:
step 1: solve for y in first equation to use substitution
y = -2x + 1
step 2: insert into second equation to eliminate y variable and work with two variables
3(-2x+1) + z = 1 (now distribute)
-6x + 3 + z = 1 (bring over the -3)
-6x + z = -2
step 3: now left with -6x + z = -2 and x + 4z = 1, so eliminate z
-6x + z = -2 (multiply by 4)
4(-6x + z = -2)
-24x + 4z = -8
-
x + 4z = 1 (brought down third equation)
-25x = -9
x = 9/25
then just plug in x into the third equation to solve for z, followed by plugging it into the first equation to solve for y. you should end with y = 7/25 and z = 4/25
I believe the answer is "b", sorry if i am incorrect.
<span>The correct answer is A. younger than. This is all just fancy ways of saying that if you cut open a mountain and look at the rocks, the ones on the top will be younger than the ones on the bottom. That is because of the ways that the rocks formed and the way things were deposited.</span>
A. a heuristic they apply the appropriate knowledge before even choosing the answer from what they know before
Answer:
A. equal compression between cylinders.
Explanation:
Equal compression between cylinders lead to uniform propelling of the shaft which in turn results into smooth motion of the shaft hence a smoothly operating engine.
In case of unequal compression, there shall be experienced unequal propelling which shall in turn result to rough engine operation
