F(3)= 9 bc 4(3)=12 12-3=9
The third equation is correct.
Answer:
40
Step-by-step explanation:
highest=2(lowest)+7
Replace the variables here:
87=2(lowest)+7
minus 7 on both sides
80=2(lowest)
divide both sides by 2
40=lowest
Answer:
B = 64° , C = 26°
Step-by-step explanation:
2x+x-6+90 =180
3x + 84 = 180
3x = 180 - 84
3x = 96
x = 32°
B = 2x
B = 2 * 32
B = 64°
C = x - 6
C = 32 - 6
C = 26°
We have that
<span>the level of the surface of the ocean is level zero
</span>therefore
the elevation of the fish is = 0+12=+12 meters (<span>the positive sign tells me that it is above the surface of the ocean)
the answer is 12 meters</span>
