How do you solve the equation in detail :: 12(2w-3)=6w

Daniel [21]

$12(w-3)=6w
$
Distrubute the 12
$12(2w)-12(3)=6w$
$24w-36=6w$
Subract 24w from both sides
$-36=6w-24w$
$-36=-18w$
Divide both sides by -18
$w=2$

What equation represents a line that passes through (4,1/3) and has a slope of 3/4

AysviL [449]

$\bf (\stackrel{x_1}{4}~,~\stackrel{y_1}{\frac{1}{3}})
\qquad \qquad \qquad \qquad 
% slope = m
slope = m\implies \cfrac{3}{4}
\\\\\\
% point-slope intercept
\stackrel{\textit{point-slope form}}{y- y_1= m(x- x_1)}\implies y-\cfrac{1}{3}=\cfrac{3}{4}(x-4)\implies y-\cfrac{1}{3}=\cfrac{3}{4}x-3
\\\\\\
y=\cfrac{3}{4}x-3+\cfrac{1}{3}\implies y=\cfrac{3}{4}x-\cfrac{8}{3}$

Given that the two triangles are congruent for which value of x are the triangles congruent?

Whitepunk [10]

Answer: 1

Since the triangles are congruent, the side lengths will also be equal.

2x - 3 = x - 2

2x - x = - 2 + 3

x = 1

So if x is 1 then the two triangles will be congruent...

The altitude (i.e., height) of a triangle is increasing at a rate of 2 cm/minute while the area of the triangle is increasing at

s344n2d4d5 [400]

Answer:

A = 1/2 B H area = 1/2 base X height

B = 2 A / H = 2 * 99 / 12 = 16.5 cm

dA / d t = 1/2 * (B dH / dt + H dB / dt)

dB / dt = (2 dA / dt - B dH / dt) / H

dB / dt = (2 * 1.5 cm^2 / min - 16.5 cm * 2 cm / min) / 12 cm

dB / dt = (3 - 33) / 12 cm/min = -2.5 cm/min
