Answer:

x = 3

Step-by-step explanation:

2 - 2x = -3 - -1

2 - 2x = -4

-2x = -6

-2x / -2 = 1x

-6 / -2 = 3

ur answer is then 1x = 3 or x = 3.

A builder wants to build the bridge whose cross section is shown in the diagram. Two companies offer simple bids on building the

leva [86]

The length of the bridge is the distance from the beginning to the end.

<em>The distance b between each beam is 9ft.</em>

Let:

<em /> $I \to$ <em> I-Beam</em>

<em /> $d_I \to$ <em> distance between I beam and the bridge</em>

<em /> $b \to$ <em> distance between each I beam</em>

<em />

Given that:

$I = \frac 34 ft\\$

$d_I = 3 ft$

<em /> $Length = 55ft\ 6in$ <em> --- length of the bridge</em>

<em />

From the diagram (see attachment), there are: 6 I-beams.

So, the length of the 6 I-beams is:

$L_1 = 6 \times I$

$L_1 = 6 \times \frac 34$

$L_1 = \frac {18}4$

$L_1 = 4.5ft$

There are 2 I-beams beside the bridge

So, the distance between the 2 I-beams and the bridge is:

$d_1 =2 \times d_I$

$d_1 =2 \times 3ft$

$d_1 =6ft$

There are 5 spaces between the I-beams

So, the length of the total spaces is:

$L_2 = 5 \times b$

$L_2 = 5b$

The total length is:

$Length = L_1 + d_1 + L_2$

So, we have:

$4.5ft + 6ft + 5b = 55ft\ 6in$

Collect like terms

$5b = 55ft\ 6in - 4.5ft - 6ft$

$5b = 44.5ft\ 6in$

Convert inches to feet

$5b = 44.5ft\ + \frac{6}{12}ft$

$5b = 44.5ft\ + 0.5ft$

$5b = 45ft$

Divide both sides by 5

$b = 9ft$

<em>Hence, the distance (b) between each beam is 9ft.</em>

Suppose that the length l, width w, and perimeter P of a rectangle are differentiable functions of t. Suppose also that the leng

Paraphin [41]

Answer:

$\dfrac{dP}{dt}=8\dfrac{dw}{dt}$

Step-by-step explanation:

The perimeter, <em>P</em>, is given by

$P(t) = 2(l(t)+w(t))$

Since $l(t) = 3w(t) + 22$ ,

$P(t) = 2(3w(t) + 22+w(t)) = 2(4w(t)+22) = 8w(t)+44$

Differentiating <em>P</em> with respect to <em>w</em>,

$\dfrac{dP}{dw} = 8$

But

$\dfrac{dP}{dw} = \dfrac{dP}{dt}\times \dfrac{dt}{dw} = \dfrac{dP}{dt}/\dfrac{dw}{dt}$

$\dfrac{dP}{dt} = \dfrac{dP}{dw} \times \dfrac{dw}{dt} = 8\dfrac{dw}{dt}$
