Answer:

Option 2nd is correct

x - 5y = 10 and 4x + 3y = 9

Step-by-step explanation:

Given the system of equation:

0.01x-0.05y = 0.1                ....[1]

0.4x+0.3y = 0.9                  ....[2]

We can write equation [1] as:

\frac{1}{100}x -\frac{5}{100}y = \frac{1}{10}

Multiply both sides by 100 we get;

x-5y = 10

We can write equation [2] as:

\frac{4}{10}x +\frac{3}{10}y = \frac{9}{10}

Multiply both sides by 10 we get;

4x+3y=9

⇒the system of equation we get;

x-5y = 10

4x+3y=9

Therefore, the systems which is equivalent to the given system is:

x - 5y = 10 and 4x + 3y = 9

A quadrilateral has angle measures of 35.8°, 25.4°, and 178°. What is the other angle measure?
Mariulka [41]

Answer:

120.8°

Step-by-step explanation:

the total angle sum is of 360 so we add and subtract

35.8+25.4+178= 239.2

360-239.2= 120.8

so the missing angle measure is 120.8°
