What is the solution of -(x + 1) - 5 > 10
Pie
<span> -(x + 1) - 5 > 10
 -x - 1 - 5 > 10
 - x - 6 > 10
Add 6 to the both sides, 
-x - 6 + 6 > 10 + 6
-x > 16
x < -16  [ changed sign 'cause changed -sign ]

In short, Your Answer would be x < -16

Hope this helps!</span>

A 9,000-lb load is suspended from the roof in a shopping mall with a 16-ft-long solid aluminum rod. The modulus of elasticity of
Westkost [7]

Answer:

Step-by-step explanation:

Given:

elongation, x = 0.50 in

Force, f = 9000 lb

Young modulus, E = 10,000,000 psi

Maximum Stress, Sm = 30000 psi

Length, L = 16 ft

Converting ft to in,

12 in = 1 ft

=16 × 12 = 192 in

Young modulus, E = stress/strain

Stress = force/area, A

Strain = elongation, x/Length, L

E = f × L/A × E

1 × 10^7 = stress/(0.5/16)

= 26041.7 psi

Minimum stress = 26041.7 psi

Maximum stress = 30,000 psi

Stress = force/area

Area = 9000/26041.7

= 0.3456 in^2

Stress = force/area

Area = 9000/30000

= 0.3 in^2

Using minimum area of 0.3 in^2,

A = (pi/4)(d^2)

0.3 in^2 = (pi/4)(d^2)

d = 0.618 inches

diameter, d = 0.618 inches

I’ll fail if I don’t get this right pls help
son4ous [18]

Step-by-step explanation:

In order to find the number of solutions, we have to expand both sides out first.

3(x - 2) + 7x =  \frac{1}{2} (6x - 2)

First, expand 3(x-2), which will obtain 3x-6.

Next, expand (1/2)(6x-2), which gives 3x - 1.

The result at this point should be as shown below:

3x  - 6 + 7x = 3x - 1

Now, we would shift all x terms to the left and all number terms to the right.

3x + 7x - 3x =  - 1 + 6

After simplifying, the final equation would be:

7x = 5

This is a linear equation and it has one solution.

x =  \frac{5}{7}
