In order to find an average, you have to add all the numbers and divide by the number of things you added.
120.37 + 108.45 + 114.86 = 343.68
343.68/3 = 114.56

Answer:
4(3x +8)
Step-by-step explanation:
You are being asked to factor 4 from each of the terms of the expression and use the distributive property to show the result.
12x +32
= 4(3x) +4(8)
= 4(3x +8)
The numbers that go in the boxes, left to right, are ...
4, 3, 8
Let the numbers be x and y. Then xy = -30 and x+y = -3.
Solve xy = -30 for y: y = -30/x
subst. -30/x for y in x+y= -3: x - 30/x = -3
Multiply all 3 terms by x: x^2 - 30 = -3x, so x^2 + 3x - 10 = 0
Solve this quadratic equation for x. x: {-5, 2}
If x = -5, then x+y = -3 becomes -5 + y = -3, and y = 2.
You should check to determine whether x=2 is also correct. If it is, what is the corresponding y value?
