Answer:
za=24
Step-by-step explanation:
supplementary angles add up to equal 180
180=7x+x+30+6
step 1 combine like terms
180=8x+36
step 2 subtract 36 from each side
144=8x
step 3 divide each side by 8
x=18
now we just plug in 18 to x in x+6
18+6=24
Answer:
the answer to the problem is for the first on it's -2
1/ y/x + x/y
x in the denominator goes in the numerator.
So, the equation becomes,
x/y + x/y
On adding the above variables, we get
x + x/y
= (2x)/y
The simplified version of the given equation becomes (2x)/y
Add up the sum and divide.
