What number best completes both equations? 5/7÷1/3=? ?×1/3=5/7
Nat2105 [25]

Consider the given equations:

The first equation is as:

\frac{5}{7} \div \frac{1}{3} = ?

So, \frac{5}{7} \div \frac{1}{3}

= \frac{5}{7} \times \frac{3}{1}

Multiplying the given fractions, we get as

= \frac{15}{7}

Now, consider the second equation as:

? \times \frac{1}{3} = \frac{5}{7}

Multiplying by '3' to both the sides of the equation, we get

? \times \frac{1}{3} \times 3 = 3 \times \frac{5}{7}

? = \frac{15}{7}

So, the number which best completes both the equations is \frac{15}{7}.

Solve for x.....................
Aliun [14]

Answer:

15

Step-by-step explanation:

In order to find the the value of x, first we need to calculate the length of the perpendicular dropped from the right angle to the hypotenuse of the given triangle.

Therefore, by geometric mean property, we have:

l(perpendicular)  \\ =  \sqrt{9 \times (25 - 9)}  \\ =  \sqrt{9 \times 16}  \\ =  \sqrt{144}  \\  l(perpendicular) = 12 \: units \\  \\ Now \: by \: Pythagoras \: Theorem:\\  {x}^{2}  =  {9}^{2}  +  {12}^{2}  \\  {x}^{2}  = 81 + 144 \\  {x}^{2}  = 225 \\ x =  \sqrt{225}  \\ x = 15
