Find the right quotient. 12x a y b ÷ (-6x a y)

Elena-2011 [213]

Answer: - 2 b

Step-by-step explanation:

Here the given expression,

$\frac{12xayb}{-6xay}$

= $\frac{12\times x\times a\times y\times b\times x^{-1}\times a^{-1}\times y^{-1}}{-6}$ $( \frac{1}{a^x} = a^{-x} )$

= $-2 x^{1-1}\times a^{1-1}\times y^{1-1}\times b$

$(a^m\times a^n = a^{m+n})$

= $-2\times x^{0}\times a^{0}\times y^{0}\times b$

= $-2 \times b$ $( a^0 = 1 )$

= $- 2b$

Answer:

x = 6, ∠B = 50°

Step-by-step explanation:

a) 8x + 2 + 70 + 60 = 180

8x + 132 = 180

8x = 180 - 132 = 48

x = 48/8 = 6

b) ∠B = 180 - 70 - 60 = 50°

or 8x + 2 = 8*6 + 2 = 50°
