Answer: y=\frac{3}{5}-\frac{2}{5}x

Step-by-step explanation:

Move the variables to the right:

2x+5y=3

5y=3-2x

Divide both sides:

5y=3-2x

y=\frac{3}{5}-\frac{2}{5} x

Solution:

y=\frac{3}{5}-\frac{2}{5} x

What is the length of AC?
Alenkasestr [34]
So in order to find line AC you must find line AD and DC then plus them together.

to find AD use Pythagoras theorem
a^2 = c^2 - b^2
AD^2 = 7.5^2 - 6.5^2
AD^2 = 56.25 - 42.25
AD^2 = 14
square root both sides to get rid of the ^2
AD ≈ 3.7 or 3.74

Do the same for DC
DC^2 = 10^2 - 6.5^2
DC^2 = 100 - 42.25
DC^2 = 57.75
DC ≈ 7.6

now plus AD and DC which should give u 11.3

Help me please i don't understand this thanks ​
STALIN [3.7K]

Answer:

12.75

Step-by-step explanation:

12.75 rounded to the nearest tenth is 12.8, and 12.74 won't work because it will round to 12.7.

Therefore, 12.75 is the smallest possible number.
