Ben has a collection of 812 stamps. He gives his brother 345 stamps. About how many stamps does Ben have left

dedylja [7]

It is given in the question that

Ben has a collection of 812 stamps. He gives his brother 345 stamps.

And we have to find how many stamps does Ben have left .

Let x stamps are left.

So we have

$x+345=812$

Subtracting 345 from both sides

$x+345-345 = 812-345$

$x = 467$

Therefore after giving 345 stamps to his brother, 467 stamps are left .

Find the value of a and b if root3-1/root3+1+ root3+1/root3-1=a+root3 b

Digiron [165]

Answer:

a=4 and b = 0

Step-by-step explanation:

Given : $\dfrac{\sqrt 3 -1}{\sqrt 3+1}+\dfrac{\sqrt 3+1}{\sqrt 3-1}=a+\sqrt 3 b$

To find, The value of a and b

Solution,

Solving LHS of the given equation,

$\dfrac{(\sqrt 3-1)^2+(\sqrt3+1)^2}{(\sqrt 3+1)(\sqrt 3-1)}=a+\sqrt 3 b$

Since,

$(a-b)^2=a^2+b^2-2ab\\\\(a+b)^2=a^2+b^2+2ab\\\\(a-b)(a+b)=a^2+b^2$

So,

$\dfrac{3+1-2\sqrt 3+3+1+2\sqrt 3}{3-1}=a+\sqrt 3 b\\\\4=a+\sqrt 3 b$

or

$4+0=a+\sqrt 3 b$

On comparing we get :

a = 4 and b = 0

Z varies directly as x2. If z = 16 when x = 2, find z when x = 5.<br> ...<br> Z=

PtichkaEL [24]

Answer:

100

Step-by-step explanation:

it is a bit unclear to me, what that problem description means.

if I understand it correctly, than z is directly depending on x².

so, z = 16 for x = 2. x² = 4

I pondered a little bit, as there are several possibilities to connect 16 with 4 as a driving factor (e.g. 2⁴ = 16, 4×4 = 16, 12 + 4 = 16).

I decided to go with the simplest interpretation with the usual meaning of "varies" (multiplication) : 4×x²

that would mean

z = 4×x² = 4×5² = 4×25 = 100
