Answer:
x=3or-1
Step-by-step explanation:
x-3 (5x-6)=3-10x
5x^2-15x-6x+18=3-10x
collect like terms
5x^2+18-3=15x+6x-10x
5x^2+15=11x
5x^2-11x+15=0
factorise
(x-3) (5x+5) =0
...... x=3 or -1
pls like if helpful nd rank me as most helpful ans
Answer:
x = 52, y = 26
Step-by-step explanation:
x - 2y = 0
40 - y = 14
(40 - 40) - y = 14 - 40
- y = -26
y = 26
x - 2(26) = 0
x - 52 = 0
x (- 52 + 52) = 0 + 52
x = 52
Answer: x = 12
Step-by-step explanation:
Ratio x coordinates = 20/10
ratio y coordinates = 10/5

Major arc CBD measures 300°. Which is the radian measure of its corresponding central angle?
a)4pi/3 radians
b) 5pi/6 radians
c) 5pi/3 radians
d) 11pi/6 radians
Answer:
c) 5pi/3 radians = 5π/3 radians
Step-by-step explanation:
The corresponding central angle can be defined as the angle that is formed when there is a joining together of two radii at the center of the circle.
The circumference of a circle is given as
360° = 2πr
The major arc CBD is 300°
Therefore,
360° = 2πr , radius is not given hence , 360° = 2π
300° = Y (Unknown)
Cross multiply
360Y= (300× 2π)
Y = 600π ÷ 360
Y = (5π÷ 3) radians
Y = 5π/3 radians
Hence the radian measure for the corresponding angle is = 5π/3 radians
