It has been estimated that 40% of marriages end in divorce. If you randomly select 9 recently married couples what is the probability that at least one of the marriages will end in divorce?

A- 0.0101
B- 0.9899
C- 0.9744
D- 0.1296

b is 38 degrees.

a is 52 degrees.

this is because if b is 38 and a is 14 degrees more than b than 38+14=52 and 52+38=90 degrees. hope this .

fa tha first one you gonna add y to both sides

it look like this

x-y+y=6+y

x=y+6

therefore your answer is

x =y+6

fa tha second one

you gonna flip tha equation

it gonna look like x-4y=y

then add 4 to both sides

it gonna look like tha

x-4 +4 =y +4

so therefore tha answer is x=y+4
