Answer:
1. 4*10^7
2. 5.1*10^-7
3.9,842,000,000(9.842*10^9)
(8y + 17) = (6x - 7)
(3x -29) + (6x -7) = 180
9x -36 = 180
9x = 216
x = 24
(8y + 17) = (6x - 7)
8y + 17 = 6(24) - 7
8y + 17 = 144 -7
8y = 120
y = 15
I hope this helps!! (and hope it’s correct hahah :))
2x - 3 = 8
add 3 to both sides
2x = 11
divide both sides by 2
x = 5.5

Answer: Choice C</h3>
cos(a - b) = cos(a)cos(b) + sin(a)sin(b)
In this case, we'd have a = 180 and b = q, so,
cos(a-b) = cos(a)cos(b) + sin(a)sin(b)
cos(180 - q) = cos(180)cos(q) + sin(180)sin(q)
cos(180 - q) = -1*cos(q) + 0*sin(q)
cos(180 - q) = -cos(q) + 0
cos(180 - q) = -cos(q)
