Answer:

$\frac{3 \times 4}{5 \times 4} x - \frac{3 \times 5}{4 \times 5} x = - \frac{2 \times 4}{5 \times 4} - \frac{1 \times 4}{5 \times 4}$

$\frac{12x - 15x}{20} = \frac{ - 8 - 4}{20}$

/·20

12x-15x = -8-4

-3x= -12. /·(-1)

3x=12

x=4

Step-by-step explanation:

$\frac{3}{5} x - \frac{3}{4} x = - \frac{2}{5} - \frac{1}{4}$

A desk is on sale for $380 which is 20% of the original price. Which equation can be used to determine the amount of money saved

elena-s [515]

Answer:

S = 380 - 380*80%

Step-by-step explanation:

Given:

The original price of the desk: $380
Discount: 20%

So, the new price of the desk after discounting is:

380(100% - 20%)

= 380*80%

= 304$

The amount of money saved: 380 - 304 = 76$

Hence, the equation can be used to determine the amount of money saved is:

Saving = 380 - 380*80%

Hope it will find you well.

What is the value of x? 3x−8=8x+4/2 Enter your answer in the box

krek1111 [17]

For this case we must find the value of "x" of the following expression:

$3x-8 = \frac {8x + 4} {2}$

Multiplying by 2 on both sides of the equation:

$2 (3x-8) = 8x + 4\\6x-16 = 8x + 4$

Subtracting 8x from both sides of the equation:

$6x-8x-16 = 4\\-2x-16 = 4$

Adding 16 to both sides:

$-2x = 4 + 16\\-2x = 20$

Dividing between -2 on both sides:

$x = \frac {20} {- 2}\\x = -10$

Answer:

$x = -10$
