$\dfrac{\sqrt7}{3}+\dfrac{5}{2\sqrt7}=\dfrac{\sqrt7}{3}+\dfrac{5\sqrt7}{14}=\dfrac{14\sqrt7}{42}+\dfrac{15\sqrt7}{42}=\dfrac{29\sqrt7}{42}$

Step-by-step explanation:

<em>LOOK AT THE PICTURE</em>

In ΔABC:

$\sin\alpha=\dfrac{x}{y+p}\\\\\cos\alpha=\dfrac{q}{y+p}\\\\\tan\alpha=\dfrac{x}{q}$

In ΔADC

$\sin\alpha=\dfrac{y}{x}\\\\\cos\alpha=\dfrac{z}{x}\\\\\tan\alpha=\dfrac{y}{z}$

In ΔBCD

$\sin\alpha=\dfrac{z}{q}\\\\\cos\alpha=\dfrac{p}{q}\\\\\tan\alpha=\dfrac{z}{p}$

1/3x-4=3/4x+1. 12(1/3x)-4=12(3/4x) + 1. 4x -4=9x + 1. -5=5x. X = -1<br><br> Solve

Answer:

x=-12

Step-by-step explanation:

$\frac{1}{3}x - 4 = \frac{3}{4} x+ 1$

To remove the denominator we take LCD

LCD of 3 and 4 is 12

In the second step we multiply the whole equation by 12 not only the fractions

$12*\frac{1}{3}x - 4*12= \frac{3}{4} x*12+ 1*12$

Now the denominator gets removed

1/3 * 12 = 4 , also 3/4 times 12 = 3*3 = 9

4x - 48 = 9x + 12

Subtract 9x on both sides

-5x - 48 = 12

Now add 48 on both sides

-5 x = 60

Divide both sides by -5

so x= -12

The value of x= -12

J is between H and K. If HJ = 2x + 5, JK = 3x - 7, and KH = 18, find the value of x

irina1246 [14]

We know that HJ + JK = HK

So lets substitute each part for their equation.

(2x + 5) + (3x - 7) = 18

Combine like terms

5x -2 = 18

Add 2 to both sides to eliminate it

5x = 20

Divide both sides by 5

x = 4

Let me know if you have any questions about this! :)
