Multiple the second equation by 2 and subtract it from the first
2x + 5y = 10
2x - 6y = -12
now subtract
11y = 22
y = 2
Plug y = 2 in to either equation
x - 3(2) = -6
x - 6 = -6
x = 0
The point at where they intersect is (0, 2)
Angle Y = 104 degrees
Angle X = 70 degrees
Answer:
500 minutes
Step-by-step explanation:
100% = x
15% = 75
We multiply 75 by 100 and divide the answer by 15
7500 / 15 = 500 minutes
Answer:
u = 40° , v = 40° and x = 100°
Step-by-step explanation:
i) from the rule of triangle we know that the sum of all three angles = 180°
ii) 100° + 40° + y = 180°. Therefore y = 40°. where y is the angle adjacent to v.
iii) from theorem on parallel lines we can say that u = y =40°
iv) from the properties of parallel lines we get v = 40° as interior alternate angles are equal.
v) again from the properties of parallel lines we get u = 40°
vi) using the triangle property as in i) we can see that u + v + x =180° therefore 40° + 40° + x = 180°. Therefore x = 100°.
vii) Therefore u = 40° , v = 40° and x = 100°
