Based on the information given, it should be noted that the correct option is C. 3x - 8.
<h3>
Solving equations.</h3>
From the information given, it was stated that Kim has 8 dollars less than twice Ricky. This will be:
= (2 × x) - 8.
= 2x - 8
Also, Ricky has x dollars. Therefore, the amount that they have together will be:
= 2x - 8 + x
= 3x - 8

<em><u>True staments are:</u></em>
The y-variable will be eliminated when adding the system of equations
There is only one solution to the system of equations
<em><u>Solution:</u></em>
<em><u>Given system of equations are:</u></em>
x + 6y = 16 ----- eqn 1
8x - 6y = -2 ---- eqn 2
We have to solve the system of equations
When we add eqn 1 and eqn 2, then y term will get eliminated
Let us add eqn 1 and eqn 2
x + 6y + 8x - 6y = 16 - 2
6y and -6y will get eliminated
Thus, y-variable will be eliminated when adding the system of equations
x + 8x = 14
9x = 14
x = 1.55
Substitute x = 1.55 in eqn 1
1.55 + 6y = 16
6y = 16 - 1.55
6y = 14.45
y = 2.408
Thus the solution is x = 1.55 and y = 2.408
There is only one solution to the system of equations

Answer: Null hypothesis =
Alternative hypothesis =
Step-by-step explanation:
Given claim : 74% of workers got their job through college.
In proportion , 0.74 of workers got their job through college.
Let p be the proportion of workers got their job through college.
Then claim :
We know that the null hypothesis always takes equality sign and alternative hypothesis takes just opposite of the null hypothesis.
Thus, Null hypothesis =
Alternative hypothesis =
