Answer:

Option c, 35

Step-by-step explanation:

<A and <B are supplementary,

so, <A+<B = 180

or, 3x-9+2x+14=180

or, 5x+5=180

or, 5x=175

or, x=35

See below

Step-by-step explanation:

4(x + 5) = 9x + 4x − 34

4x + 20 = 9x + 4x − 34 [Distributive]

4x + 20 = 13x − 34 {Combine Like Terms]

4x - 13x + 20 = 13x - 13x − 34 [Subtractive: -13x both sides]

-5x + 20 = - 34 [Combine Like Terms]

-5x + 20 - 20 = -34 - 20 [Subtractive: - 20 both sides]

-5x = -54 [Combine Like Terms]

x = -54/-5 [Division Property: divide both sides by -5]

x = - 10 4/5

$\bf \cfrac{75}{x}=\cfrac{\frac{100}{1}}{\frac{47}{5}}\implies \cfrac{75}{x}=\cfrac{100}{1}\cdot \cfrac{5}{47}\implies \cfrac{75}{x}=\cfrac{500}{47}\implies 75\cdot 47=500\cdot x

\cfrac{3525}{500}=x\implies \cfrac{141}{20}=x\implies 7.05=x$
