How to solve 10m-2/5=48/5
Romashka [77]

Answer:

Step-by-step explanation:

10m-2/5=9 and 3/5

10m-2/5=9.6 (where 9 and 3/5 is equal to 9.6)

50m-2=48 (i multiplied 10m by 5 and 9.6 by 5)

50m=50 ( i added 2 to both sides)

m=1 ( i divided by 50 to both sides to find m)

If 7 is the mean of 10,3,4,a,6,9 and 10.find the value of a
nydimaria [60]

Answer:

a = 7

Step-by-step explanation:

I think, what you need to do, is first understand how to find the mean of anything: It's quite simple, actually, just add up all the numbers, then divide that number by the number of numbers. So, let's put it in perspective:

10, 3, 4, a, 6, 9, 10

7 is the mean. 7 is the number of numbers.

If, to find the mean is: 10 + 3 + 4 + a + 6 + 9 + 10= 7a ÷ 7, then: 10 +3 + 4+ 6 + 9 +10= 42

42 plus what divided by 7 is the question now.

42 + a ÷  7= 7

So, 7 times 7, that's 49 minus 42 and you've got your answer: 7
