The speed of a sparrow is x km/h in still air. When the

Semmy [17]

Answer:

x = 5m/s

Step-by-step explanation:

Distance flying out = 12 km (headwind)

Distance flying back = 12 km (tailwind)

total distance = 12 + 12 =24 km

wind speed = 1km/h

speed going out (with headwind) = (x - 1) km/h

speed coming back (with tailwind) = (x + 1) km/h

Time taken to go out = distance going out / speed going out

= 12 / (x-1)

Time taken to come back = distance coming back / speed coming back

= 12 / (x+1)

total time = time taken to go out + time taken to come back

5 =[ 12/(x-1) ] + [ 12/(x-1)]

expanding this, we will get

5x² - 24x - 5 = 0

solving quadratic equation, we will get

x = -1/5 (impossible because speed cannot be negative)

x = 5 (answer)

Bess [88]

Answer:

The equation to describe the situation is $p-3=17.$

And, the total weight of the basket of apples was 20 pounds.

Step-by-step explanation:

The question is incomplete so, the complete question is below:

Liang bought a basket of apples to make pies for her friends. The basket of apples weighed p pounds. Before she had time to make the pies, she ate 3 pounds of apples. There are 17 pounds of apples left to make pies. Write an equation to describe this situation. What was the total weight of the basket of apples?

Now, to write an equation to describe the situation. And to find the total weight of the basket of apples.

So, the basket of apples total weighed = $p\ pounds.$

Liang ate apples weighed = 3 pounds.

And the apples left for the pies weighed = 17 pounds.

Now, to write an equation describing the situation:

$p-3=17.$

Thus, the equation is $p-3=17.$

Now, to get the total weight of the basket of apples:

$p-3=17\\\\Adding\ both\ sides\ by\ 3\ we\ get:\\\\p=20$

Hence, the basket of apples total weighed = 20 pounds.

Therefore, the equation to describe the situation is $p-3=17.$

And, the total weight of the basket of apples was 20 pounds.
