In ΔOPQ, \text{m}\angle O = (2x-5)^{\circ}m∠O=(2x−5) ,{m}\angle P = (3x-8)^{\circ}m∠P=(3x−8) and \text{m}\angle Q = (10x-17)^{\circ}m∠Q=(10x−17) What is the value of x?x?

1. 0.3 •4 is the same as 4 groups of 0.32. 7•0.8 is the same as 7 groups of 0.83. it increases by 0.5 every time, so 0.5x4 it increases by 0.9 every time, so 0.9x5. 0.9•12=10.86. 0.47•5=2.35i can finish the next ones in a separate post
