4 0

The right answer is Option C.

Step-by-step explanation:

Given equations are;

-2x+4y=17   Eqn 1

3x-10y= -3   Eqn 2

Adding Eqn 1 and Eqn 2;

(-2x+4y)+(3x-10y)=17+(-3)\\-2x+4y+3x-10y=17-3\\3x-2x-10y+4y=14\\x-6y=14

The right answer is Option C.

Express 0.361 recurring as a fraction.<br> (only the 61 recurs)
Oduvanchick [21]

9514 1404 393

Answer:

  179/495

Step-by-step explanation:

When the repeating decimal starts at the decimal point, the repeating digits can be turned into a fraction by putting them over the same number of 9s. That is, 0.61616161... is equivalent to 61/99.

Here, the repeating part is 1/10 that value, so is 61/990. This is added to the non-repeating part, which is 0.3 = 3/10.

Then the entire decimal is ...

  0.361_61 = 3/10 + 61/990 = (297 +61)/990 = 358/990 = 179/495

What is the perimeter of the figure to the nearest tenth of a millimeter?
Pavlova-9 [17]
We have to calculate the perimeter of the figure to the nearest tenth of a millimeter. This figure is made of a rectangle and a half of a circle. The first figure has the perimeter: 3 + 6 + 3 = 12 mm. The second figure has the perimeter: 2 * Pi * r / 2 = Pi * r ; and the radius : r = 6/2 = 3 mm. So Pi * 3 = 3.14 * 3 = 9.42. Fimally : 12 + 9.42 = 21.42 or 21.4 to the nearest tenth. Answer: C. 21.4 millimeters<span>. </span>
