Step-by-step explanation:
y=mx+c
Take c from both sides:
y-c = mx
Divide both sides by m:
(y-c) / m =x
Now swap sides to make it prettier:
x = (y-c) / m
Answer:
82 grams

Answer:
The expression $32/x represents the price per pound.
Step-by-step explanation:
Given:
$32 for X pounds of beef ribs.
Now, the symbol which represents the per is this → / .
So, $
shows the expression for the price per pound.
Therefore, the expression $32/x represents the price per pound.
The Mean would increase to 82.17 or a total increase of .17
You have 99 students and the avg is 82, therefore we can multiply 99*82 to get our total points
99*82=8118
We add a single score of 99 to our total points 8118+99= 8217
Then we add the student to the total number of students bringing it to 100 and divide our new total by the our new number of students.
8217/100 = 82.17
Answer:
1. QS and RT= 15
2. Im not positive but I think it's TQ=18
Step-by-step explanation:
For question 1, you would do 6x+3=8x-1 and solve to get the result of x=2
Then you'd plug in 6 and get QS and RT=15
For the second one I am unsure because I wasn't positive how to solve but it seems like the side RQ might be 1/2 of TQ. Sorry if thats wrong I can try and help more if you need
