The equivalent expression of 1/2 + 3c + 4/5 is \frac{13 + 15c}{10}

<h3 /><h3>How to determine the equivalent expression?</h3>

The expression is given as:

1/2 + 3c + 4/5

Take the LCM of the expression

\frac{5 + 15c + 8}{10}

Evaluate the like terms

\frac{13 + 15c}{10}

Hence, the equivalent expression of 1/2 + 3c + 4/5 is \frac{13 + 15c}{10}

Find the value of x.<br> (5x +13)<br> (4x+ 2)°<br> (2x -9)
SOVA2 [1]

Answer:

x = 20

Step-by-step explanation:

By exterior angle theorem, we have:

(4x + 2) \degree + (2x  - 9) \degree = (5x + 13) \degree \\  \\(4x + 2 + 2x - 9) \degree  = (5x + 13) \degree\\  \\(6x  - 7) \degree  = (5x + 13) \degree \\  \\ 6x - 7 = 5x + 13 \\  \\ 6x - 5x = 13 + 7 \\  \\ x = 20

Which pair of inequalities would overlap if they were graphed?
dsp73

Answer:

x ≤ 10, x > 4

Step-by-step explanation:

If x is less than or equal to 10, the line starts on 10 and includes all the numbers to the left . . <u>. .-2-1 0 1 2 3 </u><u>4 5 6 7 8 9 10</u>,11,12,. . .

If x is greater than 4 it's  . -1,0,1 2 3 <u>4,5 6 7 8 9 10</u><u> 11 12 13 . . </u>.

So there is an overlap of the numbers between 4 and 10 (not including 4, just a little more. . )

torisob [31]

Answer:

\tan 3x=\frac{\sqrt{3} }{3} =\frac{1}{\sqrt{3} } =tan\frac{\pi }{6} =tan (n\pi +\frac{\pi }{6} )\\3x=n\pi +\frac{\pi }{6} =\frac{(6n+1)\pi }{6} \\x=\frac{(6n+1)\pi }{18} \\where~x~is~an~integer.

Step-by-step explanation:

tan 3x=\frac{\sqrt{3} }{3} =\frac{1}{\sqrt{3} } =tan\frac{\pi }{6} =tan (n\pi +\frac{\pi }{6} )\\3x=n\pi +\frac{\pi }{6} =\frac{(6n+1)\pi }{6} \\x=\frac{(6n+1)\pi }{18} \\

where~x~is~an~integer.
