First try to isolate the variable, in this case "y". the first step to this is add 5/6 to both sides to get 5y/42=5/6. next multiply each side by 42 to get 5y=35. next divide by 5 to get y=7. so y=7 is the answer.
Answer:
of oil.
Step-by-step explanation:
Firstly, you need to find the LCD (lowest common denominator), this can be done by factoring the denominators and knowing the multiples.
In this case, you can see that 2 is a factor of 8 so we can simply multiply
so that the denominator is 8:
8 ÷ 2 = 4

Now the fractions can be added easily:

=
of oil.
Hope this helps!
Answer:
2 : 1
Step-by-step explanation:
Since the triangles are similar then the ratios of corresponding sides are equal, that is
AC : DF = 8 : 4 = 2 : 1
