Answer:
a=4220-2t
This would be if we are finding the altitude of the submarine from the surface of the water(how many meters away from the surface it is). I don't know what it would be if you want to know from the bottom of the ocean.
Answer:
a(c-b) = d
Use the distributive property, which states: x(y-z) = xy - xz
a(c-b) = ac - ab
ac - ab = d
Add ab on both sides
ac = d + ab
Divide both sides by a to isolate c

Answer:
4. 2/6 (There are 6 sides. Only 2 are not factors.)
5. 3/12
6. 2/12
7. 3/12
8. 3/12
9. 6/23
10. 9/12
Step-by-step explanation:
These make sense if you do the math in your head.

Circle equation: (x - h) + (x - k) = r²
(h, k) = center
r = radius
The center is (-7, 4)
To find the radius, take the square root of 49.
√49 = 7
The radius is 7.
Best of Luck!
Answer:
(C) 5
Step-by-step explanation:
x+7=2y
<em>Subtract 7 from both sides</em>
x=2y-7
2y-7=x
<em>Multiply both sides by 2</em>
4y-14=2x
y=2x−1
<em>Add 1 to both sides</em>
y+1=2x
<u>Combine equations:</u>
y+1=4y-14
<em>Add 14 to both sides</em>
y+15=4y
<em>Subtract y from both sides</em>
15=3y
3y=15
<em>Divide both sides by 3</em>
y=5
<u>The answer is </u><u>(C) 5.</u>
