Step-by-step explanation:

<h3>★ Solution:-</h3>

$\sf \leadsto \dfrac{7x - 3}{5x - 2} = -2$

$\sf \leadsto 7x - 3 = -2(5x - 2)$

$\sf \leadsto 7x - 3 = -10x + 4$

$\sf \leadsto 7x + 10x = 4 + 3$

$\sf \leadsto 17x = 7$

$\sf \leadsto x = \dfrac{7}{17}$

Hence the value of x is 7/17

What percent of 146 is 39

marissa [1.9K]

Answer:

Step-by-step explanation:

Percentage solution with steps:

Step 1: We make the assumption that 146 is 100% since it is our output value.

Step 2: We next represent the value we seek with x.

Step 3: From step 1, it follows that 100% = 146.

Step 4: In the same vein, x% = 39.

Step 5: This gives us a pair of simple equations:

100% = 146(1).

x%=39(2).

Step 6: By simply dividing equation 1 by equation 2 and taking note of the fact that both the LHS (left hand side) of both equations have the same unit (%); we have

100/x% = 146/39

Step 7: Taking the inverse (or reciprocal) of both sides yields

x% / 100% = 39/146 ⇒ x= 26.71%

Therefore, 39 is 26.71% of 146.

Solve to indicated variable 16ak=-5 for a

damaskus [11]

The answer is
$\frac{ - 5}{16k} = a$
steps
#1) Try to leave a by itself by dividing any variable next to it
$\frac{16 ak = - 5 }{ 16k}$
you can only divided these variables as all these variables in the original equation. are being multiplied. The opposite if multiplication is division.
