Ok so:
4(4x+3) = 19x + 9 - 3x +3
parenthesis first:
4 x 4x = 16x then 4 x 3 = 12
16x + 12 = 19x + 9 - 3x + 3
combine :) :
19x - 3x = 16x then 9 + 3 = 12
16x + 12 = 16x +12
-12 -12
16x = 16x
They are the same equations lol they equal 0.
Answer:
x > 80,000
Step-by-step explanation:
3600+1.02x<2000+1.04x
The first thing we need to do is to isolate the x's and get all of them on one side, let's start off by subtracting 2,000 from both sides of the equation.
1,600+1.02x<1.04x
Now, subtract 1.02x from both sides to get both the x's on one side.
1600<0.02x
Divide by 0.02 to solve for x.
80,000<x
We can flip the sign and swap the places of the number and variable so that x is on the left side.
x > 80,000
Given: Mean μ = 61.2 and standard deviation σ =21.4
The Z score of the value x=45 is given by
Z = 
Z = 
Z = 
Z = -0.757
The z-score value for 45 rounded to nearest tenth is -0.8
