Breaking down:
\frac{3}{15}  =  \frac{1}{5}
{w}^{6}  \div  {w}^{2}  =  {w}^{4}
{v}^{5}  \div v =  {v}^{4}

Therefore,
\frac{3 {w}^{6} {v}^{5} }{15 {w}^{2}v } \\  =  \frac{{w}^{4} {v}^{4}  }{5}

Hope this helps. - M

Evaluate the inverse trigonometric function Sin^-1(-1). Give answers in both radians and degrees.
grin007 [14]

Answer:

B) Sin^-1(-1) = 3pi/2 or 270°

D) Sin^-1(-1) = -pi/2 or -90°

Step-by-step explanation:

Sine function:

The sine function is -1 at 270º(-90º), which is 3pi/2 = -pi/2.

Inverse sine:

The input of the inverse sine function is a value, and the output are the angles which have the sine equal to the input.

Sin^-1(-1)

Angles for which the sine are -1, that is 3pi/2 or 270° and -pi/2 or -90°. Thus, options B and D are correct.

Solve this equation:<br><br> α ÷ 6 + 4 = 16
Ilia_Sergeevich [38]
\alpha \div 6 + 4=  16\\\\Subtract ~4~on~both~sides\\\\ \alpha \div 6 +4 -4 = 16 -4\\\\ \alpha \div 6 = 16 - 4\\\\ \alpha \div 6 = 12\\\\Multiply~both~sides~by~6\\\\a \div 6\times 6 = 12\times 6\\\\ \alpha = 12\times 6 \\\\ \boxed{\bf{\alpha = 72}}

Your final answer is alpha = 72.

What is 6(5-8v)+12=-54
stira [4]
V=2 bc when u distribute the 6 to the numbers in the parenthesis u get 30-48v+12=54 then u subract 12 on both sides getting 30-48v=-66 then u subtract 30 on both sides making it -48v=-96 and mental math leads to -48•2=-96

Please walk me through this​
FinnZ [79.3K]

Answer:

X is 160. because you can add all the value of x. But first substrate 540 with 100 which is 440. then 1/2x + 1/2x+ (x-15) + (x-25) which is further simplified as x + 2x - 40. then it's further simplified as 3x - 40 = 440. then add 40 with 440 which is 480 then divide it by 3 which is 160. therefore X= 160.
