Answer:
1=8
2=16
5=40
6=48
10=80
12=96
Step-by-step explanation:
you have to multiply by 8 with the left numbers and you divide by 8 with the right numbers
Answer:
x = 195.8
Step-by-step explanation:
x/8.9 = 22
multiply by 8.9 to remove the fraction
Answer:
3) No solution
4) No solution
Step-by-step explanation:
3) The equation simplifies to ...
5x +15 = 5x +3
15 = 3 . . . . . . . . . . subtract 5x; no value of x will make this true
There is no solution.
__
4) The equation simplifies to ...
4 = -5 . . . . . . . . . subtract y; no value of y will make this true
There is no solution.
13, 17, 15, 18, 21, 13, 20;(the add 3.7 has no place in this data set .Ignore it)
1) arrange the data from smaller to greater: 13 13 15 17 18 20 21
2) mean: Add up all data & divide by the number of data
that is 7==> (117/)/7 so the mean = 16.71
3) Median is the central value of the data point that is in the middle of the sequence, so the median is 18
4) Mode the number that is most repeated & it's 13 (repeated twice)
5) The range is the difference between the largest & the smallest
Range = 21-13 ==> Range = 8
There is a problem in answers you have written: Either you mistyped or omitted something or the answer are false. With the data you gave me, my methodology is 100% right
