The range of the data is 6.
Answer:
x= -7/5 y=8/5
Step-by-step explanation:
1. choose a variable to eliminate (i chose 6)
2. multiply the first equation by 2 and the second equation by 3
3. now you have
-6x+6y=18
6x-21y=-42
and the x's can now cancel out when you add the equations together
4. after adding the equations, you get
-15y=-24
5. solve for y (y= 8/5)
6. now plug in 8/5 for the y in one of the original equations to solve for x. (i chose the first one)
7. -3x+3(8/5)=9
-3x+24/5=9
-3x=21/5
x= -7/5
Correct because X doesn't repeat its self
For the
problems presented, the answer would be the following:
1. Givens
are:
Θ – 25 degrees
<span>µ = 0.27 </span>
g = acceleration due to
gravity = 9.8 m/sec^2
Answer
would be <span>a = 2.14 m/sec^2.</span>
2. Givens are:
<span>N = 257.32 newtons </span>
<span>f = 0.27(257.32) </span><span>
<span>f = 69.48
N </span></span>
Answer would be <span>a = 2.80 m/sec^2 </span>
I am hoping that these answers have satisfied your queries
