30 * 1/5 = 6 so 6 have a cell phone
1/2 * 6 = 3 so 3 have a cellphone and social media
195 divide by 2 1/2

Answer: £164. 85
Step-by-step explanation:
169.95/100 x 3/1
= 1.6995 x 3
Interest= 5, 0985

= £50,815
Answer:
always true
Step-by-step explanation:
Distribute the left side
2(x + 3) = 2x + 6
Simplify the right side
5x + 6 - 3x ← collect like terms
= 2x + 6
Thus
left side = right side , so always true
146. They are asking for the angle XY, the blue line.
For instance, imagine it is 90 deg, instead of 73, it would cut the circle in two, and XY would be 180 deg. Imagine it would be 45 degrees, it would leave a quadrant, and that's 90 deg.
So the angle * 2 (they are different angles)
I think 'TheBestBrain' thought they were asking for the supplementary angle, but I think it is the arc length angle (blue line)
