Answer:
Step-by-step explanation:
x=17
Let's solve your equation step-by-step.
6(x−5)=72
Step 1: Simplify both sides of the equation.
6(x−5)=72
(6)(x)+(6)(−5)=72(Distribute)
6x+−30=72
6x−30=72
Step 2: Add 30 to both sides.
6x−30+30=72+30
6x=102
Step 3: Divide both sides by 6.

Answer:
the first oe
Step-by-step explanation:
Honestly math is hard at but i need points so that’s why i’m here so i hope this works
From the points given we know that the rectangle is 3 points wide and 2 points tall. If we rotate it
around the x axis then we will receive the lying cyllinder which will be 3 points tall and 2 points wide (so its radius is 2/2 = 1 point). Now we can find the surface area of the cyllinder using appropriate formula:

Answer:</h3>
(x, y) = (0.3, 0.1)
<h3>
Step-by-step explanation:</h3>
The sum of the probability numbers must be 1. That is, ...
... 0.6 + x + y = 1.0
The expected value must be 22.5. That is, ...
... 20·0.6 +25x +30y = 22.5
These two equations can be written as the system of equations ...
- 5x +5y = 2 . . . . . . the first equation in standard form
- 5x +6y = 2.1 . . . . . the second equation with 5 factored out (after subtracting 12)
Subtracting the first of these equations from the second gives ...
... (5x +6y) -(5x +5y) = (2.1) -(2)
... y = 0.1
Putting this in the very first equation above, we have ...
... 0.6 +x +0.1 = 1.0
... x = 0.3 . . . . . . . . . subtract 0.7
