What must the measure of angle LMN be? m∠LMN = °

luda_lava [24]

Both 25x and 22x + 9 have the same answers. So you set those two equal to each other.
$25x = 22x + 9$
Subtract 22x from both sides.
$3x = 9$
and you're left with this.
Next, divide 3 from both sides.
$x = 3$
re-insert 3 into one of the equations.
$25(3) = 75$
add up both angles
$75 + 75 = 150$
all angles (for quadrilaterals)added up equals 360.
$150 + 2x = 360$
solve for x. Subtract 150 from both sides.
$2x = 210$
and divide 2 from both sides
$x = 105$
AngleLMN= 105

The course grade in a statistics class is the average of the scores on five examinations. Suppose that a student's scores on the

nadya68 [22]

Answer:

84 is the highest possible course average

Step-by-step explanation:

Total number of examinations = 5

Average = sum of scores in each examination/total number of examinations

Let the score for the last examination be x.

Average = (66+78+94+83+x)/5 = y

5y = 321+x

x = 5y -321

If y = 6, x = 5×6 -321 =-291.the student cannot score -291

If y = 80, x = 5×80 -321 =79.he can still score higher

If If y = 84, x = 5×84 -321 =99.This would be the highest possible course average after the last examination.

If y= 100

The average cannot be 100 as student cannot score 179(maximum score is 100)
