What does x equal in this equation

Answers

Answer 1

Answer:

3ax + b = c

subtract b from each side

3ax +b-b = c-b

3ax =c-b

divide each side by 3a

3ax/3a = (c-b)/3a

x = (c-b)/3a

Choice C

Find the mode and median of the data. A. mode = 41 median = 72 B. mode = 72 median = 94 C. mode = 94 median = 94 D. mode = 94 median = 72

Answers

mode means the number that apperss the most
median is the number in the middle when you arrange them in numerical order

ok so
you take the unbers fom the left most collumn and pair it with each number in the right side of the line, the left collumn is the tens place and the right hand side is the ones

so the th enumbers are

32,41,41,50,56,57,62,70,70,72,72,72,73,74,91,92,94,94,94,94

mode=most common number
94 appears 4 times which is most
mode=94

median is number in very middle number

72 is in middle

mode=94
72=median

D is answer

Answer:

Step-by-step explanation:

You take the numbers fom the left most collumn and pair it with each number in the right side of the line, the left collumn is the tens place and the right hand side is the ones.

So the the numbers are:

32,41,41,50,56,57,62,70,70,72,72,72,73,74,91,92,94,94,94,94

Mode = Most common number

94 appears 4 times which is most

Mode=94

Median is number in very middle number

20 terms

72 is in middle

Mode = 94

Median = 72

Aiden borrows a book from a public library. He read a few pages on day one. On day two he reads twice the number of pages than he read on day one. On the third day, he reads six pages less than what he read on the first day. If he reads the entire book that contains 458 pages. Write how many pages he read on day three

Answers

Answer:

Step-by-step explanation:

On day one = few pages (x)

On day two = twice of pages read on day one (2x)

On day three= 6 less than the page read the first day (x-6)

Total pages read = x+2x+(x-6)=458

4x-6=458

4x=458+6=464

x= 464÷4

x=116

Pages read on day three was 110
