First, you would add 11x to both sides, because you are trying to separate the variable pieces and the constants (integers).
If performed correctly, you would get the equation
7x-5=6
Then, you would add 5 to both sides, to get the 7x alone.
This results in the equation 7x=11
Then, to get x alone, without a coefficient, you would need to divide both sides by 7.
x=11/7
The sum of 2.54 x 1019 and 3.218 x 1017. 3.2434 x 1036 2.57218 x 1036 3.2434 x 1019 2.57218 x 1019 is 17811.9829.
As in the given problem we can see that multiplication of decimal number followed by summation is given so we an do it by parts.
The first part is 2.54*1019=2588.26
3.218 x 1017=3272.706
3.2434 x 1036= 3360.1624
2.57218 x 1036= 2664.77848
3.2434 x 1019=3305.0246
2.57218 x 1019=2621.05142
The sum is 17811.9829.

, we calculate the z-scores using the formula:
#The z-score for 1910 can be calculated as:
#The z-score for 1230can be calculated as:
#The z-score for 2190 is calculated as follows:
#The z-score for 1380 is calculated as:
Answer:
-7.2
Step-by-step explanation:
-3 (1.2) 2= -3×1.2×2
-3×1.2×2
-3.6×2
-7.2
-3 (1.2) 2= -7.2
Answer:
C
Step-by-step explanation:
If you have a Ti-84 series calculator, press "stat" then "Edit..." and then fill in the data table values for x and y in two lists. Then press "2nd" and "mode" to quit. Now press "stat" again and right arrow over to "calc" and press down until you find "ExpReg" and set the "Xlist" and "Ylist" that you used and you will get C as the answer. Another way to do this is to manually substitute values into all 4 equations, which is boring.
