The sum of a number and 6 is 8 more than twice the number. Find the equation that could be used to find this number . A Ox+6 = 2x +8
BOX+6 = x +8
cOx+6 = 2(X + 8)
DO 6x = 2X + 8

The correct answer is D

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
