25:405=\frac{25}{405}=\frac{5\cdot5}{81\cdot5}=\frac{5}{81}

                                                       1 4 0 

We've got the same difference before. That means numbers will be repeated.
So:
      25:405 = 0.0 6 1 7 2 5 9 2 (3 4 5 6 7 9 0 1 2)

Pls help. i will give brainliest
fenix001 [56]

Answer:

247 = j - 285

Step-by-step explanation:

Anything that is labeled with "is" will be what the entire equation is equal to. (Also because the instructions are asking for an equation which is equal to something). Also, fewer than is the subtraction of two things. In this case it will be 285 and j. In the end the equation will be:

247 = j - 285

Hope this helped.

Please help me !!!!
liq [111]

Answer:

...

against the wind, an airplane travels 3640 km in 7 hours.

with the wind, the same plane travels 6000 km in 6hrs.

...

let speed of plane in still air be x mph

speed of wind be y mph.

..

t=d/r

..

against wind speed = x-y mph

with wond speed = x=y mph

...

3640/(x-y)=7

3640 = 7x-7y

/7

520=x-y.....................1

...

6000/x+y = 6

6000 = 6x+6y

/6

1000=x+y.....................2

...

Add (1) & (2)

2x=1520

/2

x=760 mph speed of plane in still air

...

plug value of x in 2

1000=760+y

100-760=y

240 = y

240 mph speed of wind

Another one omg this is annoying
Alexeev081 [22]

Answer:

Correct option: first one

Step-by-step explanation:

The equation f(x) = 5x + 1 is a function, because each value of x gives only one  value of y.

Now let's find the inverse by switching f(x) by x and x by f'(x), then isolating f'(x):

x = 5f'(x) + 1

5f'(x) = x - 1

f'(x) = \frac{x - 1}{5}

The inverse f'(x) is also a function, because each value of x gives only one value of x.

So we have that both the equation and its inverse are function, therefore the correct answer is the first option.
