Answer 1

Ответ:

(98:14+х-9:24)х40=480

98:14+х-9:24=480/40

7+х-3/8=12

х=12-7+3/8

х=5 цел 3/8

Пошаговое объяснение:

Answer 2

-7695:х=25-44
-7695:х=-19
х=-7695:(-19)
х=405

Answer 3

To solve the equations, we can follow these steps:

Equation 1: $\frac{44 - 7695}{x} = 25$

Step 1: Subtract 44 from both sides of the equation. $- \frac{7695}{x} = -19$

Step 2: Multiply both sides by $-x$. $7695 = 19x$

Step 3: Divide both sides by 19. $x = \frac{7695}{19}$ $x = 405$

Equation 2: $( \frac{98}{14} + x - \frac{9}{24} ) \times 40 = 480$

Step 1: Simplify the fractions. $( \frac{7}{1} + x - \frac{3}{8} ) \times 40 = 480$

Step 2: Combine the constants in the parentheses. $( 7 + x - \frac{3}{8} ) \times 40 = 480$

Step 3: Multiply both sides by $\frac{8}{3}$ to eliminate the fraction. $( 7 + x - \frac{3}{8} ) \times \frac{8}{3} \times 40 = 480 \times \frac{8}{3}$

$( 56 + 8x - 10 ) \times \frac{8}{3} = 1280$

Step 4: Distribute the fraction and simplify. $( 56 \times \frac{8}{3} + 8x \times \frac{8}{3} - 10 \times \frac{8}{3} ) = 1280$

$( \frac{448}{3} + \frac{64x}{3} - \frac{80}{3} ) = 1280$

Step 5: Combine the constants. $\frac{448 - 80}{3} + \frac{64x}{3} = 1280$

$\frac{368}{3} + \frac{64x}{3} = 1280$

Step 6: Subtract $\frac{368}{3}$ from both sides. $\frac{64x}{3} = \frac{1280 - 368}{3}$

$64x = 3 \times 304$

Step 7: Divide by 64. $x = \frac{3 \times 304}{64}$ $x = \frac{912}{64}$ $x = 14.25$

So, the solutions are $x = 405$ for the first equation and $x = 14.25$ for the second equation.
