Answer:
c. Cos 52 = 17/c
Step-by-step explanation:
sin(x) = cos(90-x)
1 dozen = 12

12 - 5 =
7 people left on the train
Answer:
equation: 6x = -105
answer: x = -17.5
Step-by-step explanation:
the product of 6 and a number (6x) is the same (=) as -105 (-105)
6x = -105
/6 /6
x = -17.5
So since we know what x is, we can substitute it into the original equation for x like so to solve for y...
(2y - 8) + 5y - 10 = 0
2y - 8 + 5y = 10
2y + 5y = 18
7y = 18
y = 18/7 (or about 2.57)
So now we know what x is, we can sub it into the below equation to solve for x...
x = 2(18/7) - 8
x = 36/14 - 8 (or about -5.43)
