PLS HELP ASAP!! ALGEBRA 9!! 4.29-x+36=102-2.52x+2

Mathematics
1 answer:
Andrei [34K]2 years ago

Answer:

  x = 29

Step-by-step explanation:

If the equation is :

4.2(9-x)+36=102-2.5(2x+2)

→distribute 4.2 and -2.5 in parenthesis

4.2(9 - x) + 36 = 102 -2.5(2x + 2)

37.8 - 4.2x +36 = 102 -5x -5

→  have terms with x = terms without x

Keep the terms you need the way they are, and move the terms you need on the other side of equal sign with changed sign.

4.2(9 - x) + 36 = 102 -2.5(2x + 2)

37.8 - 4.2x +36 = 102 -5x -5

 - 4.2x  +5 x  = - 37.8 - 36 + 102 - 5

→ Combine like terms

             0.8x  = 23.2

→ Divide both sides by 0.8

                    x = 29

In a class of 25 students, 24 of them took an exam in class and 1 student took a make-up exam the following day. The professor g
gavmur [86]

Answer:

The  value is   \mu_n  =  73.6

Step-by-step explanation:

From the question we are told that

   The total number of students is  N =  25

    The  number of student that took exam in class is  n  = 24

    The number that took make up exam is  k  =  1

     The  average score of the first 24 students is  \mu  =  74

       The  standard deviation is \sigma  =  8.9

      The  average score of the student who took make up test is \= x  =  64

Generally the new average is mathematically represented as

      \mu_n  =  \frac{( n * \mu ) +  \= x }{N}

      \mu_n  =  \frac{( 24 * 74 ) +  64 }{25}

       \mu_n  =  73.6
