Say x is the number

7x +3 = 39 -2x
Add 2x to each side
9x +3 =39
Subtract 3 from each side 
9x =36
Divide by 9 on each side
x=4

Hope this helped

Answer:  The required number is 2.

Step-by-step explanation:  Given that the product of 7 and a number increased by 3 is equal to twice the number subtracted from 39.

We are to find the number.

Let x represents the given number.

Then, according to the given information, we have

7(x+3)=39-2x\\\\\Rightarrow 7x+21=39-2x\\\\\Rightarrow 7x+2x=39-21\\\\\Rightarrow 9x=18\\\\\Rightarrow x=\dfrac{18}{9}\\\\\Rightarrow x=2.

Thus, the required number is 2.

A tortoise and a hare are competing in a race around a 1600-meter track. The arrogant hare decides to let the tortoise have a 78
Sindrei [870]
I am presuming that the question is who won or by how much did the winner win. 

distance equals rate times time, or d = r*t
For the Hare d = 1600 and r = 10
   1600 = 10 t 
Divide both sides by 10 
t = 160
The hare finished in 160 seconds

For the tortoise d = 1600 - 780 = 820 (due to the head start) and r = 5.3
820= 5.3 t
Divide both sides by 5.3
t = 154.72 (rounded to the hundredths place)

The tortoise won by 5. 28 seconds (160-154.72)
