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
Answer:
m∠RQS = 47°
Step-by-step explanation:
The collinear points form a "straight angle," one whose measure is 180°. That is the sum of the marked values:
(3x -5) +(x +1) = 180
4x = 184
x = 46
m∠RQS = (x+1)° = (46+1)°
m∠RQS = 47°
