Answer:
A. x = 2 and BQ = 27
Step-by-step explanation:
The key to this problem is the fact that the centroid divides the median into segments in the ratio 2 : 1.
BM : MQ = 2 : 1
BM = 2·MQ
9x = 2(5x -1) . . . . . substitute the given expressions
9x = 10x -2 . . . . . . eliminate parentheses
0 = x -2 . . . . . . . . . subtract 9x
2 = x . . . . . . . . . . . .add 2
BQ = BM + MQ = 9(2) +5(2) -1
BQ = 27
A. The master bolt was stolen.
Answer:
either you have 62.6 + 62.5 + 55
or you have 55 + 55 + 70
Step-by-step explanation:
There are only two possible answers.
Either 55 degrees is by itself and the two equal angles are something other than 55 in which case you would write it as
x + x + 55 = 180 Subtract 55 from both sides
2x + 55 - 55 = 180 - 55
2x = 125 Divide by 2
x = 125/2
x = 62.5
OR
There are 2 angles that are both 55
x + 55 + 55 = 180
x + 110 = 180
x = 70
Answer:
n + 25 = 100
n = 75
Step-by-step explanation:
When you write an equation for what's given, you get n + 25 = 100.
Then you do some simple math and subtract 25 from 100 to find n. Or 75.
