Answer: The overall average will increase by 4 from 11 to 15

Step-by-step explanation: If each of the six integers is increased by four, that will add 6×4 to the total.

The original average was based on six numbers totaling 66, then divided by 6 to get the average, 11.

So add 66 + 24 = 90

Divide 90/6 = 15. The new average.

That is 4 more than the original 11.

Alisiya [41]
1,969.35.
first you add them all up (6.45+150+500)=656.45, which is how much he rode in 1 day, no you multiply it by 3. so 3(656.45)=1,969.35 so thats how many km he rode in three days

Match the expressions given in words with their values when m=6.
Gemiola [76]

Answer:

Value of expression 1 = 3

Value of expression 2 = 42

Value of expression 3 = 15

Value of expression 4 = 2

Step-by-step explanation:

Expression 1 : the sum of m and 3 divided by the  difference of m minus 3

Expression 1: \frac{m+3}{m-3}

Substitute m = 6

So, value of expression 1=\frac{6+3}{6-3}=3

Expression 2 : the sum of 3 times m and 4 times m

Expression 2: 3m+4m

Substitute m = 6

So, value of expression 2=3m+4m=3(6)+4(6)=42

Expression 3 : the difference of the product of 3 and m  minus the quotient of m divided by 2

Expression 3:3m-\frac{m}{2}

Substitute m = 6

So, value of expression 2= 3m-\frac{m}{2}=3(6)-\frac{6}{2}=15

Expression 4 :the quotient of 6 divided by the  difference of m minus 3

Expression 4:\frac{6}{m-3}

Substitute m = 6

So, value of expression 4=\frac{6}{m-3}=\frac{6}{6-3}=2
