HERE IS YOUR ANSWER HOOMAN:
8
STEP BY STEP EXPLANATION FAM:
We have a set of four numbers and the mean is 5. We can see that the sum of the values is 20:
=5
We have another set of three numbers whose mean is 12. We can write that as:
=12
To find the mean of the seven numbers together, we can add the values together and divide by 7:
=
=8

Answer:
Mr. Berg got $4 in change.
Step-by-step explanation:
Answer:
y = -(2/3)x + 3
C
Step-by-step explanation:
The slope of the equation that was given is - 2/3
The slope in a slope intercept equation is the number in front of the x when the value of the number in front of the y = 1 and x and y are on opposite sides of the equal sign. Let's translate that.
The original equation is y = -(2/3)x + 5/3
- y and x have to be on opposite sides of the equal sign [They are]
- The slope is the number in front of the x. That's (-2/3). That makes A incorrect.
Now you need to use the given point
The point is (-3 , 5) Put this into the equation that you have so far
y = (-2/3)x + b
y = 5
x = -3
5 = (-2/3)(-3/1) + b Substitute in the givens
5 = (-2 * -3)/3 + b Multiply -2 * - 3 = 6
5 = 6/3 + b Divide the 6 by 3
5 = 2 + b Divide
5 - 2 = b Subtract 2 from both sides
3 = b Switch sides
b = 3
Answer y = (-2/3)x + 3 or C
The answer to the solution is X+3<19-x.
