6/8 is equal to 15/ what? NEED HELP ASAP PLZ will choose brainliest

The angle of a triangle are given as 6x,(x-3), and (3x+7). find x then find the measures of the angles

If x is 6, then 7x= a. 13 b. 42 c. 42x d. 76

How does the graph of g(x)=⌊x⌋−3 differ from the graph of f(x)=⌊x⌋? the graph of g(x)=⌊x⌋−3 is the graph of f(x)=⌊x⌋ shifted right 3 units. the graph of g(x)=⌊x⌋−3 is the graph of f(x)=⌊x⌋ shifted up 3 units. the graph of g(x)=⌊x⌋−3 is the graph of f(x)=⌊x⌋ shifted down 3 units. the graph of g(x)=⌊x⌋−3 is the graph of f(x)=⌊x⌋ shifted left 3 units.
