Question 9 (10 points)<br> Solve for x,<br> 2(x - 1) + 4 = 4(x + 1)

Nutka1998 [239]

1. Expand
2x − 2 + 4 = 4x + 4

2. Simply
2x + 2 = 4x + 4

3. Subtract
2 = 4x + 4 - 2x

4. Simplify
2 = 2x + 4

5.Subtract
2 - 4 = 2x

6. Simplify
-2 = 2x

7. Divide both sides by
-1 = x

8.Switch sides.
x = -1

a woman 1.65. tall stood 50m away from the foot of a tower,and observe that the angle of elevation of the top of the tower to be

ElenaW [278]

$\sf\huge\underline{\star Solution:-}$

$\rightarrow$ Let the women's height be AE and distance between the women and tower be AC.

Also let the height of tower be BC.

$\rightarrow$ Now, clearly it is forming a triangle.

So, in triangle ABC,

$\rightarrow$ $\sf{Tan50° \:= \: \frac{BC}{AC}}$

$\rightarrow$ $\sf{1.19 \:= \: \frac{BC}{50}}$

$\rightarrow$ $\sf{1.19 ×50\:= \: BC}$

$\rightarrow$ $\sf{59.5m\:= \: BC}$

$\rightarrow$ Hence, BC = 59.5m

So, BD(total height of the tower) $\sf{ = \:BC+CD}$

$\sf{= \:59.5+1.65}$

$\sf{=\: 61.15m}$

Therefore, total height of the tower = $\sf\purple{ 61.15m.}$

5p - 14 = 8p + 4<br><br> Explain

grigory [225]

1: we bring all the x to one member, changing its sign (I use x, consider it a p)
$5x - 8x - 14 = + 4$

2 we bring all the non-x to the other member
$5x - 8x = + 14 + 4$
3 we solve the members
$(5 - 8)x = - 3x$
$( + 14 + 4) = + 18$
4 we divide 18 by -3
$- 3x = + 18$
$x = 18 \div - 3$
$18 \div - 3 = - 5$
$x = - 5$
my English is so bad lol

Solve equation:<br> -3|d-5|=-6

gulaghasi [49]

Answer:

d = 7, 3

Step-by-step explanation:

First, you need to isolate the absolute value

-3|d - 5| = -6

divide both sides by -3:

|d - 5| = 2

break into 2 equations:

d - 5 = 2, d - 5 = -2

solve both equations and collect solutions:

d = 5 + 2, d = 5 - 2

d = 7, 3
