What does 6•7-27•9+64=

Natali [406]

Hi!

$6*7-27*9+64$

$42-27*9+64$

$42-243+64$

$Answer---->=-137$

Explanation: This question is super super easy to me. This question is about how to use their order of operations the math problems. First you had to used PEMDAS stands for P-Parenthesis first, E-Exponents second, M-Multiply third, D-Divide fourth, A-Add fifth, and S-Subtract sixth. Then multiply and divide from left to right with 6*7=42. Then 27*9=243,42-243+64, and add or subtract from left to right with 42-243+64=-137 is the right answer. Hope this helps! And thank you for posting your question at here on Brainly. And have a great day. -Charlie

URGENT EXPLANATION AND SOLVING

Alex787 [66]

$\cfrac{a}{\sin(a)} = \cfrac{b}{\sin(b)} 
$

$\cfrac{31}{\sin(42)} = \cfrac{37}{\sin(x)} 
$

$31\sin(x) = 37 \sin(42)$

$\sin(x) = \cfrac{37 \sin(42) }{31}$

$x = \sin^{-1}(\cfrac{37 \sin(42) }{31} )$

$x = 53 \textdegree$

Answer: 53°
