There are 495 coins in a bottle. of the coins are £1 coins.
124 of the coins are 50p coins.
The rest of the coins are 20p coins.

Work out the total value of the 495 coins.

Step-by-step explanation:

495/3 = 165

£1 = £165

124 x 0.50 = 62

50p = £62

495 - 165 - 124 = 206

206 x 0.20 = £41.20

165 + 62 + 41.20 = 268.20

total value £268.20

therefore, we can conclude that bea's uncle is 25 years old.

x² + 11x + 18 < 0  

[-11 ± sqrt(121 - 72)]/2 = (-11 ± 7)/2  

solution: (-9, -2)
