I used R for Rick since I am putting everything in Rick's case. The equation would be (R+10)+(R-8)+(R-11)=315.
Once you add the same terms you end with 4R-9=315
You add 9 to both sides
4R=324
Then divide
R=81
For Don, since his is ten point higher, his would be 91.
Rick is 81.
Jackie would be 73 since it is 8 points less.
And Jared would be 70 since it is 3 point less.
Check by adding; 81+91+73+70=315
Tell me if this helps.

A group of students was discussing the meaning of this statement. They were arguing back and forward about whether the converse
Savatey [412]

Answer:

The statement is missing. The statement is -- "A ray can be part of a line."

The answer is : The converse is not true, so Jahmiah is correct.

Step-by-step explanation:

A conditional statement is represented by showing p → q. It means if p is correct or true,  then q is also correct or true.

And the converse of p → q can be shown as  q → p.

But we know that the converse of a statement is not always true, it may be true and may not be true.

In the context, the statement is " a ray can be a part of a line." And so the converse would be  "A line can be a part of the ray".

So by definition we know that a line is continuous line having no end points, it extends in one direction. While a ray starts from a point and extends to infinity in one direction.

Thus ray is part of line but line is not a part of the ray. So the converse of the statement is not correct.

Hence, Jahmiah is correct.

Question 1:

14+2x=62        (x=Pass cost)
-14        -14
(2x=48)/2
x=24

6.50+5.75+1.15x=18
12.25+1.15x=18
-12.25          -12.25
1.15x=5.75 divide both sides by 1.15
x=5
