Answer:
17/9 or 1 8/9 if you are looking for a mixed fraction
Step-by-step explanation:
1 7/9 + 4/36
16/9 + 4/36
Multiply 16/9 by 4/4 to get the same denominator as 4/36
64/36 + 4/36
68/36 = 17/9 = 1 8/9
A triangle solver tells you
C = 85° b ≈ 8.4 c ≈ 10.4From the sum of angles of a triangle,
C = 180° -42° -53° = 85°
From the law of sines
b = sin(53°)/sin(42°)*7 ≈ 8.355
c = sin(85°)/sin(42°)*7 ≈ 10.422
Step-by-step explanation:
just look what happened :
every term was multiplied by a factor with the value 1 (to keep the original value) but to establish a common denominator.
a/b was multiplied by d/d, and c/d was multiplied by b/b, so that the common denominator is then bd.
so, the first answer option is correct.
although I am a bit unhappy with its phrasing.
but the other options are definitely wrong.
Step-by-step explanation:
8k - 12 = 3
8k = 3 +12
8k = 15
k = 15/8
k = 1.875
