Answer:

$\frac{1}{3x+52}$

Step-by-step explanation:

We begin with the expression

$\frac{\frac{1}{x^2+51x+50} }{\frac{2}{x+50}+\frac{1}{x+1} }$

First, we can split this into the product of two fractions

$\frac{1}{x^2+51x+50} *(\frac{1}{\frac{2}{x+50}+\frac{1}{x+1}} )$

Now, we can factor the denominator of the first fraction.

$\frac{1}{(x+1)(x+50)} *(\frac{1}{\frac{2}{x+50}+\frac{1}{x+1}} )$

Next, we need to create a common denominator for the second fraction

$\frac{2}{x+50}+\frac{1}{x+1}\\\\\frac{2}{x+50}*\frac{x+1}{x+1} +\frac{1}{x+1}*\frac{x+50}{x+50} \\\\\frac{2x+2}{(x+1)(x+50)} + \frac{x+50}{(x+1)(x+50)}\\\\ \frac{3x+52}{(x+1)(x+50)}$

Now to return this portion to the denominator of the second fraction.

$\frac{1}{(x+1)(x+50)} *(\frac{1}{\frac{3x+52}{(x+1)(x+50)} } )$

Dividing by a fraction is the same as multiplying as the reciprocal of the fraction, so the second fraction becomes

$\frac{1}{(x+1)(x+50)} *\frac{(x+1)(x+50)}{3x+52}$

Now to reduce this expression by canceling out $(x+1)(x+5)$

$\frac{(x+1)(x+50)}{(x+1)(x+50)(3x+52)}\\\\\frac{1}{3x+52}$

56(12-9)-6 ÷ 3*3-3 help me solve

Inessa05 [86]

Answer:

$159$

Step-by-step explanation:

$56(12 - 9) - 6 \div 3 \times 3 - 3 \\ = 56(3) - 6 \div 3 \times 3 - 3 \\ = 56 \times 3 - 2 \times 3 - 3 \\ = 168 - 6 - 3 = 159$

I need help for number 6 please

vesna_86 [32]

Answer:

Hi there!

The answer to this question is c=23, b and d=157

this is because c is the vertical angle of a meaning the values are equal

and b is the supplementary angle to a: all you do is subtract 23 from 180 to get 157.

b is vertical to d, so d is also 157
