Complementary angles sum to 90°. Supplementary angles sum to 180°.
3x + 4y = 16
-4x - 3y = -19
4( 3x + 4y = 16)
3( -4x - 3y = -19)
Distribute
12x + 16y = 64
-12x - 9y = -57
Now subtract both equations
7y = 7
/7 on both sides
y = 1
Substitute y = 1 in one of the equations.
3x + 4y = 16
3x + 4(1) = 16
-4 on both sides
3x = 12
/3 on both sides
x = 4
Answer:
x = 4
y = 1
Answer:
meters.
Step-by-step explanation:
To find diver's final location relative to the surface of water we will subtract
from
because diver dives away another
from his previous location of
.

Now we will convert our mixed fraction into improper fraction and then we will find a common denominator.

Now let us convert our answer in mixed fraction.

Therefore, diver's final location relative to the surface of the water is
meters.
