Answer:
n=2
Step-by-step explanation:
Simplify.
6−3(n−2)=8−n
6+(−3)(n)+(−3)(−2)=8+−n(Distribute)
6+−3n+6=8+−n
(−3n)+(6+6)=−n+8(Combine Like Terms)
−3n+12=−n+8
−3n+12=−n+8
Add n to both sides.
−3n+12+n=−n+8+n
−2n+12=8
Subtract 12 from both sides.
−2n+12−12=8−12
−2n=−4
Divide both sides by -2.
-2n/-2 = -4/-2
n=2
Answer:16.66 repeating years
Step-by-step explanation: take 6% of 700 the divide 700 by that number to get how many years until he doubles his money then check by multpling 42 * 16.66 repeating
Answer:
Measurement error. Took the quiz and got it right.
Step-by-step explanation:
This will be easier to write, and a lot easier to read, if we temporarily
use another symbol ... say, 'Q' ... to represent ' sin(2x) ' .
Here we go:
Original equation: Q² - 0.5 Q = 0
Factor the left side: Q (Q - 0.5) = 0
This equation is true if either factor is zero:
-- If Q=0, then sin(2x) = 0
2x = 0°, 180°, 360°
x = 0°, 90°, 180°
-- If (Q-0.5) = 0, then Q = 0.5
sin(2x) = 0.5
2x = 30°, 150°
x = 15°, 75°
The whole collection of solutions
between 0° and 360° :
x = 0°, 15°, 75°, 90°, 180° .
