You would do 2x-3+x+3x-15=360
combine like terms which then gives you
5x-18=360 then you would add 18 to both sides giving you
5x=378
and then you divide by 5 on both sides which will then give you your answer x=?
Answer:
Step-by-step explanation:
For testing of significance of correlation coefficient denoted by r, we create hypotheses in three ways
They are one tailed, two tailed. One tailed can be stated as right tailed and also left tailed.
The null hypothesis would normally be as r=0
Verbally we can say this there is no association between the dependent and independent variable (linear)
Against this alternate hypothesis is created as
either r not equal to 0
or r>0 or r<0
If r not equal to 0, we say two tailed hypothesis test
If r>0 is alternate hypothesis, it is right tailed test
If r<0 is alternate hypothesis, then it is left tailed test.

Here is the original equation, lets solve this step-by-step
(x + 2)/4 = 5
Now, lets find out how.
We must apply the inverse operation.
4/2 is the reciprocal, so lets multiply that to both sides.
4/2 = 2
5*4 = 20
4x + 8 = 20
-8 -8 Subtract 8 from both sides. (Inverse operation)
4x = 12
4x/4 = 12/4 Divide 4 by both sides (Inverse)
x = 12/4
x = 3 Simplified
