Evaluate. -2(x + 6) + 3 = -11x + 4(x + 4) The value of x is ___​
Yanka [14]

-2(x + 6) + 3 = -11x + 4(x + 4)

-2x - 12 + 3 = -11x + 4x + 16

-2x - 9 = -7x + 16

5x = 25

<em>x = 5</em>

Hope this helps! :)

Does anyone know how to do these?
ale4655 [162]

Answer:

D.

Step-by-step explanation:

f(x) = \sqrt[3]{4x}

g(x) = 2x + 3

\frac{f}{g} (x)  = 'f' divided by 'g'

\frac{\sqrt[3]{4x} }{2x+3}    Substitute.

x cannot be -\frac{3}{2} because that would create a zero in the denominator.

That's a no-no.

It makes it 'undefined'

Given: m angle P equals open parentheses 5 x minus 27 close parentheses degree, m angle Q equals open parentheses 4 x minus 7 cl
max2010maxim [7]

Answer: Side QR

Step-by-step explanation: The sum of a triangle internal angles is 180°. So to determine the angles, we calculate x:

5x - 27  +4x - 7 + 3x + 10 = 180

12x = 204

x = 17

With x, solve for the angles:

m∠P = 5(17) - 27 = 58

m∠Q = 4(17) - 7 = 61

m∠R = 3(17) + 10 = 61

The relationship between angles and sides in any triangle:

  • the largest angle is opposite the largest side;
  • the middle angle is opposite to the middle-sized side;
  • the shortest angle and side are opposite to each other;

So, the shortest side of PQR is the side opposite to the shortest angle.

The shortest angle is m∠P = 58°. Therefore, the shortest side is QR

14 is 28% of what number
Sindrei [870]
'is' in mathematics means the equal sign
'of' in mathematics means the multiplication sign
the number can be any variable you chose it to be

14 = \frac{28}{100} \times x

Divide both sides by 28

\frac{1}{2} = \frac{x}{100}

Multiply by 100 on both sides to isolate 'x'

\boxed{\bf{x=50}}

14 is 28% of 200
