|-3|=3 right?
Then it is
3*-6=-18
90=6x+3x
90=9x
90/9=x
10=x
3x=3*10=30
6x=6*10=60
hope this helped
unfortunately I cant manage to understand ur question
First, we get the z-score using formula:
z =( X - μ ) / σ
From the problem, we substitute the given values:
z = (9 - 7.8) / 1.7
z = 0.71
From the z-table (one-tailed), for a z-score of 0.7059, the proportion of numbers that are greater than 9 is 0.76.
Answer:
they will start with $122.75 dollars to be paid and add on 8% of $122.75 which is $9.82.
the next step would be to add together 122.75+9.82 and you get $132.57
the last step woukd be to find what 18% of 132.57 is and that would be $23.86
add 132.57+23.86=$156.43
$156.43 is your answer
