Distribute 2/5 and 3/5 into the ():
2/5(a+b)+3/5(a+c)
2/5 a+ 2/5 b+3/5 a+ 3/5 c
combine the like terms:
2/5 a+3/5 a= 5/5 a --> 1a --> a
new simplified equation:
a+2/5 b+3/5 c
no it is not one x cannot have 2 y's.
the answer is 65 degrees because the line in the middle is a 180 degree angle and 180-115=65. hope this helps :)
Is/of = %/100
plug in your known values
is/4 = 275/100
cross multiply & divide
11 = is
11 is 275% of 4
D. combine like terms, 4+7 is 11 and -3 and -10 is -13
