Answer:

I get x = 3 and y = 2

Step-by-step explanation:

Add the 2 equations and you get 2x = 6, so x = 3.

Substitue 3 for x in both original equations and solve for y. If you get the same y for both equations you have an answer.

I get x = 3 and y = 2

Answer:

20°

Step-by-step explanation:

$arc \: length = \frac{ \theta}{360 \degree} \times circumference \\ \\ \frac{1}{3} = \frac{ \theta}{360 \degree} \times 6 \\ \\ \theta = \frac{360 \degree}{18} \\ \\ \theta =20 \degree$

If 400 reduced by two times my present age is 296, how old am I now?

vitfil [10]

Answer:

52 years.

Step-by-step explanation:

Represent my current age by c. Then 400 - 2c = 296, or

104 = 2c

Then c must be 104/2, or 52 years.

Can someone tell me step by step how to solve this?

sasho [114]

Answer:

Step-by-step explanation:

I take it that this is some sort of ratio. Start by solving the brackets on the left.

Brackets: 1/3 - 1/10

Brackets: 10/30 - 3/30

Brackets: 7/30

Brackets^2: 49/900

Brackets^2 - 1/5: 49/900 - 180/900

Brackets^2 - 1/5: -131/900

(2/5)^2 = 4/25

The way this read, it should be

$\frac{\frac{-131}{900} }{\frac{4}{25} }$

Which when you invert and multiply becomes

$\frac{-131}{900} * \frac{25}{4}$

which finally becomes

$\frac{-131}{144}$
