Answer:
2/25
Step-by-step explanation:
1/4 (v - 7) = 2
1/4v - 1/4 (7/1) = 2
1/4v - 7/4 = 2
1/4v = 15/4
Multiply by 4/1 on both sides to get v
(4/1) 1/4v = 15/4 (4/1)
v = 60/4
v = 15
Answer:
Step-by-step explanation:
Equation given
tan(3B-32 ) = cot ( 5B +10 ) = tan [ 90 - ( 5B + 10 ) ]
tan(3B-32 ) = tan (90 - 5B - 10 )
(3B-32 ) = (90 - 5B - 10 )
8B = 32 + 80
B = 14° .
Answer:
5:6 --> 10:12
Step-by-step explanation:
A good way to think of this is to provide a perspective: there are 5 boys every time there is 6 girls. So if there is 10 boys, that means there would be 12 girls (because 5 *2 = 10 and 6*2 = 12).
tl:dr: 5 *2 = 10 so 6*2 = 12
The correct answer would be B
