4(4x+3)=19x+9-3x+3 what are the steps
TEA [102]
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.

Solve algebraically for x 3600+1.02x<2000+1.04x
pickupchik [31]

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 a mean of 61.2 and a standard deviation of 21.4, what is the z-score of the value 45 rounded to the nearest tenth?0.8−0.90
kherson [118]

Given: Mean μ = 61.2 and standard deviation σ =21.4

The Z score of the value x=45 is given by

Z = \frac{x - mean}{standard deviation}

Z = \frac{45 - 61.2 }{21.4}

Z = \frac{-16.2}{21.4}

Z = -0.757

The z-score value for 45 rounded to nearest tenth is -0.8
