Answer:
1) 42
2) 41
Step-by-step explanation:
1) 7 + x = 49
Subtract 7 from both sides.
x = 49 - 7 = 42
2) 5 + x + 3 = 49
Combine like terms.
x + 8 = 49
Subtract 8 from both sides.
x = 49 - 8 = 41
Here sin theta is positive and tan theta is negative , it means theta is in second quadrant where cos is negative too .
So the correct option is the third option .
Answer:
5.7 hours
Step-by-step explanation:
average speed = distance / time
rewriting gives
time = distance / average speed.
distance = 320 km
average speed = 56 km/hour
so
time = 320 / 56 = 5.7 hours
Y = -1/2x + 4
X + 2y = -8
Replace y in the second equation with the first one:
X + 2(-1/2x +4)=-8
Simplify:
X -X +8 = -8
Simplify:
8 = -8
Subtract 8 from both sides:
0 = -16
This is a false statement, so there are no solutions.
