I answer this question before this is the solution just change the total of $2750:
Two mechanics worked on a car, The first mechanic worked for 20 hours and the second mechanic worked for 5 hours together they charged a total of $1150.
Let's make,
mechanic #1's rate = x
mechanic #2's rate = y
* Their rate is dollars per hour ($/hr)
mechanic #1 worked for 20 hours (hr × $/hr = $)
20x = money earned by mech#1
and mechanic #2 worked for 5 hours
5y = money earned by mech#2
together they charged a total of $1150. So the amount of money earned by both mechanics.
20x + 5y = 1150
the sum of the two rates was $95 per hour.
x + y = 95
which means
x = 95 - y
plug (95 - y) in for "x" in the other equation to get everything in terms of one variable.
20(95 - y) + 5y = 1150
solve for y
1900 - 20y + 5y = 1150
1900 - 15y = 1150
-15y = 1150 - 1900
-15y = -750
y = -750/-15
y = 50 $/hr
Now use this to solve for x
x + y = 95
x + 50 = 95
x = 95 - 50
x = 45 $/hr
mech#1 charged 45$/hr
mech #2 charged 50$/hr

i dont know how 2 explain this but you have to do the traditional way of multiplying PLS MARK BRAINLIEST
★ A random sample of nine walleye pike from Salty Lake gave the following weights rounded to the nearest pound.

Before going to the question, let's review what range is:
Range is the difference between the greatest number and the least number in a data set. Finding range is pretty easy. All you need to do is find the greatest number and lowest number, and find the difference.
In this data set, you have the following numbers:
The greatest number is 11. The lowest number is 2. That means that the range is equal to:
Subtract:
★ The range is 9 ; range = 9
