Answer:

13/2

Step-by-step explanation:

$y$ is the number of medals won. So for the number of medals to be equal in both the case we have to equate $y$ in both the equations.

Thus we would have:

$3x + 5 = 5x - 8$

Solving for $x$ we have: $2x = 13$ .

$\implies x = \frac{13}{2}$

Answer: First option.

Step-by-step explanation:

You need to remember the following Trigonometric Identity:

$cos\alpha =\frac{adjacent}{hypotenuse}$

In this case, you can identify in the figure that:

$\alpha =35\°\\adjacent=9\\hypotenuse=x$

Then you must substitute these values into $cos\alpha =\frac{adjacent}{hypotenuse}$ :

$cos(35\°) =\frac{9}{x}$

Finally, you need to solve for "x" in order to find its value. This is:

$(x)(cos(35\°))=9\\\\x=\frac{9}{cos(35\°)}\\\\x=10.98$

Rounding the result to the nearest tenth, you get:

$x\approx11$
