For this case we must simplify the following expression:

$-2 (x-3)$

By definition we have that the distributive property establishes that:

$a (b + c) = ab + ac$

So, if we have:

-2 (x-3)

We take into account the law of multiplication of signs:

$- * + = -\\- * - = +$

So:

$-2 (x-3) = - 2x + 2 * 3 = -2x + 6$

Answer:

$-2x + 6$

Mrs.Gill won certain prize money in a cooking competition.She spent half of the prize money on the clothes,one third on grocery

erma4kov [3.2K]

Answer

Find out the how much prize money did she win.

To proof

Let us assume that the total amount prize money did she win be u.

As given

Mrs.Gill won certain prize money in a cooking competition.

She spent half of the prize money on the clothes

$= u -\frac{u}{2}\\ = \frac{u}{2}$

one third on grocery

$= \frac{u}{2} -\frac{u}{3}$

(L.C.M of (2,3) =6 )

$= \frac{3u -2u}{6} \\=\frac{u}{6}$

gave away the remaining Rs.2000 to an orphanage

$2000 = \frac{u}{6}$

u =Rs 12000

Rs 12000 prize money did she win.

Hence proved

If PQR ~ UTV, find the value of x.

user100 [1]

The value of x is 15.

Solution:

Given ΔPQR $\sim$ ΔUTV.

<em>If two triangles are similar, then the corresponding parts are congruent.</em>

$$\Rightarrow \frac{PR}{UV} =\frac{RQ}{VT}$

$$\Rightarrow \frac{14}{x + 6} =\frac{8}{x -3}$

Do cross multiplication, we get

⇒ 14(x - 3) = 8(x + 6)

⇒ 14x - 42 = 8x + 48

Add 42 on both sides.

⇒ 14x = 8x + 90

Subtract 8x on both sides.

⇒ 6x = 90

Divide by 6 on both sides.

⇒ x = 15

The value of x is 15.
