Answer:

x=2

Step-by-step explanation:

4.5x+11.5=8.5x+3.5


We simplify the equation to the form, which is simple to understand

4.5x+11.5=8.5x+3.5


We move all terms containing x to the left and all other terms to the right.

+4.5x-8.5x=+3.5-11.5


We simplify left and right side of the equation.

-4x=-8


We divide both sides of the equation by -4 to get x.

Determine the moment m that will produce a maximum stress of 70 mpa on the cross-section
gogolik [260]

The moment M that will produce a maximum stress of 70 MPa on the cross-section of 177.3 will be 13.533 kN-m.

<h3>What is bending stress?</h3>

Bending stress is the typical stress that an item experiences when it is exposed to a heavy load at a specific spot, causing it to bent and fatigue.

The moment of inertia above the neutral axis will be

Iₓₓ = 99 x 84.7³/3 - (99 - 12 x 3) (84.7 - 12)³/3

Iₓₓ = 11983247 mm⁴

The moment of inertia below the neutral axis will be

Iₓₓ = 2 x 12 x (87 - 84.7)³/3 + 12 x 177.3³/3

Iₓₓ = 22294005 mm⁴

Then the moment of inertia about the neutral axis will be

Iₓₓ = + 11983247 + 22294005

Iₓₓ = 34277252 mm⁴

Then for maximum bending stress, we have

M = σ x Iₓₓ / y(max)

We have

σ = 70 MPa

Iₓₓ = 34277252 mm⁴

y(max) = 177.3

Then we have

M = 70 x 34277252 / 177.3

M = 13.533 kN-m

2(x+3)=2x+6 how many solutions dose it have
LekaFEV [45]

<em>Answer:</em>

<em>The right side of the equation is only a different way of writing the left side, so any value of x will solve this equation. </em>

<em> </em>

<em>The equation   − 2 (  x  +  3  )  =  − 2 x  −  6  does not have any specific solutions for the simple reason that the left and rigth sides are two representations of the same equation. </em>

<em> We have  − 2 (  x  +  3  )  means that each term inside the parenthesis should be multiplied with  − 2 , i.e.</em>

<em> − 2 (  x  +  3 )  =  − 2  ⋅  x  −  2  ⋅  (  +  3 )  =  − 2 x  −  6 </em>

<em> </em>

<em>Which is exactly what the right side says. </em>

<em> </em>

<em>Any value of x will, therefore, fulfill this equation.</em>

Solve the equation (linear equation)<br><br> <img src="https://tex.z-dn.net/?f=8%5E%7B2x%2B7%7D%20%3D%20%28%5Cfrac%7B1%7D%7B32%7
Minchanka [31]

Answer: x=-1

Step-by-step explanation:

By the negative exponent rule, you have that:

(\frac{1}{a})^n=a^{-n}

By the exponents properties, you know that:

(m^n)^l=m^{(nl)}

Therefore, you can rewrite the left side of the equation has following:

(\frac{1}{8})^{-(2x+7)}=(\frac{1}{32})^{3x}

 Descompose 32 and 8 into its prime factors:

32=2*2*2*2*2=2^5\\8=2*2*2=2^3

Rewrite:

(\frac{1}{2^3})^{-(2x+7)}=(\frac{1}{2^5})^{3x}

Then:

(\frac{1}{2})^{-3(2x+7)}=(\frac{1}{2})^{5(3x)}

As the base are equal, then:

-3(2x+7)=5(3x)

Solve for x:

-6x-21=15x\\-21=15x+6x\\-21=21x\\x=-1
