y = 11/21
To solve this first evaluate the power (then calculate the sum):
<u><em>
</em></u>y - <u><em>
</em></u> = 5y +<u><em> (-5 + 7)</em></u>
16y - 9 = -5y + 2
Next Move terms (move variable to the left side and change its sign) (Move constant to the right side and change its sign):
16y <u><em>- 9 </em></u>= <u><em>-5y</em></u> + 2
16y + 5y = 2 + 9
Next Collect the like terms and calculate the sum:
<u><em>16y + 5y</em></u> = <u><em>2 + 9</em></u>
21y = 11
Lastly divide both sides of the equation by 21:
<u><em>21y = 11</em></u>
y = 
I think you solved it on your own because x is 82
Answer:
4 meters
Step-by-step explanation:
Assuming that the garden is a rectangular garden, its area would be length ×width.
Let the length be L meters and the width be W meters.
Area= L ×W
48= LW -----(1)
Given that the length is 3 times the width,
L= 3W -----(2)
Substitute (2) into (1):
48= 3W(W)
3W²= 48
Divide both sides by 3:
W²= 48 ÷3
W²= 16
Square root both sides:
W= 4 (reject negative as width cannot be a negative number)
Thus, the width of the garden is 4 meters.

Answer:
(x, y) = (34/5, -4/5) = (6.8, -0.8)
Step-by-step explanation:
Subtract the first equation from the second to eliminate x.
Substituting for y in the second equation, we can find x.
The solution is (x, y) = (34/5, -4/5) = (6.8, -0.8).

There is no mode distance, so take the middle number around 7-8. maybe 7.5.
