\bf \textit{circumference of a circle}\\\\ C=2\pi r~~ \begin{cases} r=radius\\[-0.5em] \hrulefill\\ C=60\pi \end{cases}\implies 60\pi =2\pi r\implies \cfrac{60\pi }{2\pi }=r\implies 30=r

-1/2 + 1 1/2 + 3 - n
GREYUIT [131]

Answer:

The answer all together would be 5 minus n.

Step-by-step explanation:

a negative and a positive equals a positive so -1/2 + 1 1/2 would equal 2 and 2 + 3 equals 5. Then, the remaining numbers are 5 and n. The final answer is 5 minus n because n is unknown.

Please help..I dont get this and please Dont put a Link below please.

Answer:

x = 27, y = 74

Step-by-step explanation:

Hi again :)

Since the angles of 5x + 4 and the one adjacent to x = 14 are corresponding angles, they are equal. That means that (5x + 4) + (x + 14) = 180 degrees.

5x + 4 + x + 14 = 180

6x + 18 = 180

6x = 162

x = 27

Also, the angle (5x + 4) and (2y - 9) are vertical angles, they are equal in value. We know the value of x now, so we'll substitute that in and solve for y.

5(27) + 4 = 2y - 9

135 + 4 = 2y - 9

139 = 2y - 9

148 = 2y

y = 74

As always, lmk if you have questions.

2/11 + (4/11 + 1/11) = (2/11 + 4/11) + 1/11<br>Solve with step​
aniked [119]

Answer:

\frac{7}{11}  =  \frac{7}{11}

Step-by-step explanation:

\frac{2}{11}  + ( \frac{4}{11} +  \frac{1}{11} ) = ( \frac{2}{11}  +  \frac{4}{11} ) +  \frac{1}{11} \\   \frac{2}{11}  +  \frac{5}{11}  =  \frac{6}{11}  +  \frac{1}{11}  \\  \frac{7}{11}  =  \frac{7}{11}  \\
