Answer:
48.75
Step-by-step explanation:
340/80=16 1/4
16 1/4*3=48.75
3x4=5x-10
12=5x-10
22=5x
x=4.4
Step-by-step explanation:
put some x values into the equation
i.e : -2, -1, 0 ,1 ,2
3/5 (-2) +2 = 4/5 (-2, 4/5)
3/5 (-1) +2 = 7/5 (-1, 7/5)
3/5 (0) +2 = 2 (0, 2)
3/5 (1) +2 = 2.6 (1, 2.6)
3/5 (2) +2= 3.2 (2, 3.2)
Then plot these on the graph as corodinates with the x values
We know that we can use trigonometry to solve for x here.
If we use tangent, we can solve for x directly:




So therefore we have solve for x, which is D)
