Answer:
Answer: 1/12
Step-by-step explanation:
2/5x-4=8-3/5x.
We want to tank x out of the denominator by multiplying x on both sides.
2/5-4x=8x-3/5
Now we simplify
-12x=-1
x=1/12
Put x in the equation to check it
Answer:

3x=240
x=80
so bob score =80
Answer:
Part 1) 
Part 2) 
Step-by-step explanation:
step 1
Find the value of x
In the right triangle of the figure
---> opposite side angle of 30 degrees divided by the hypotenuse
Remember that
substitute
solve for x
step 2
Find the value of y
In the right triangle of the figure
---> adjacent side angle of 30 degrees divided by the hypotenuse
we have
substitute
