3 0

Answer:

Step-by-step explanation:

10 x = x - 3 Subtract x from both sides

10x - x = - 3 Combine like terms on the left

9x = - 3 Divide both sides by 9

9x/9 = -3/9

x = - 1/3 or x = - 0.333333

Is 300 mm greater than 3 cm

rewona [7]

Answer:

Yes

Step-by-step explanation:

There are 10 mm in 1 cm.

We have 300 mm, so let's convert this to cm by using a proportion:

$\frac{10mm}{1cm} =\frac{300mm}{x}$ , where x is the number of cm in 300 mm.

Cross-multiplying, we get: 10x = 300, so x = 30 cm.

Clearly, 30 cm > 3 cm, so yes, 300 mm is greater than 3 cm.

Hope this helps!

Solve the equation (1 + x²)dy +xydx= 0

Tatiana [17]

Answer:

$y=\frac{c}{\sqrt[]{x^2+1} }$

Step-by-step explanation:

(1 + x²)dy +xydx= 0

$(1+x^2)dy=-xydx\\\frac{1}{y}dy=\frac{-x}{x^2+1}dx\\$

Integrate both side

$lny=-\frac{1}{2} ln(x^2+1)+c\\y=\frac{c}{\sqrt[]{x^2+1} }$
