Answer:
∠MON = 57°
Step-by-step explanation:
Given that OL and ON are perpendicular lines then ∠LON = 90° and
∠LOM + ∠MON = 90, substitute values
3x - 15 + 5x - 23 = 90, that is
8x - 38 = 90 ( add 38 to both sides )
8x = 128 ( divide both sides by 8 )
x = 16
Hence
∠MON = 5x - 23 = (5 × 16) - 23 = 80 - 23 = 57°
Answer:
i think its 200
Step-by-step explanation:
Answer:
x = 1, y = 10
Step-by-step explanation:
y = -5x + 15 --- Equation 1
2x + y = 12 --- Equation 2
Substitute y = -5x + 15 into Equation 2:
2x + y = 12
2x - 5x + 15 = 12
Evaluate like terms.
15 - 3x = 12
Isolate -3x.
-3x = 12 - 15
Evaluate like terms.
-3x = -3
Find x.
x = -3 ÷ -3
x = 1
Substitute x = 1 into Equation 2:
2x + y = 12
2(1) + y = 12
2 + y = 12
Isolate y.
y = 12 - 2
y = 10

2. 24
Step-by-step explanation:
The number of persons that drink grape milk only :
18 - 10 = 8
The number of persons that drink coffee :
42 - 8 = 34
The number of persons that drink coffee only :
34 - 10 = 24
