The answer is C for this question
Answer:
i would reword this to 6x+7=61
Step-by-step explanation:
So.
move the 7 to the right side of the equation but as an opposite number so in this case its gonna be a negative
61-7=54
then you divide the number and get your missing numbers
54/6=9
d=9
plug it in
6(9)+7=61
Answer:
Mean=8.8, Median=8
Step-by-step explanation:
How to find the mean:
First, add all the #'s up. 4+9+12+14+7+7=53
Then divide that by the number or numbers. In this case it is 6.
53/6=8.833... So rounded=8.8
Median:
List numbers lowest to highest
4, 7, 7, 9, 12, 14
Go to the middle number.
Since it is between 7 and 9, it is 7+9=16. 16/2=8
8 is the median
Answer:
10
Step-by-step explanation:
First convert them to improper fractions
5 4/6 = (5×6 + 4)/6= 34/6
4 1/3 = (4×3 + 1)/3=13/3
Now make them have the same denominator. In order to do this, you must multiple 13/3 by 2/2, so both the denominators equal 6.
13/3 × 2/2 = 26/6
34/6 + 26/6 = 60/6 = 10
