If anybody can help me pls do the average of 5 numbers is 64. When a sixth number is added, the average becomes 66. What is the sixth number?​

Step-by-step explanation:

5x64=32066=(320+x} 666x6={320+x)396=320+x=396-320

i would need to see the dot plot : )

example 2 – simplify: step 1: completely factor both the numerators and denominators of all fractions. step 2: change the division sign to a multiplication sign and flip (or reciprocate) the fraction after the division sign; essential you need to multiply by the reciprocal. step 3 : cancel or reduce the fractions.
