Let <span>p time in minutes speaking Polish
</span>let <span> h </span> time in minutes speaking <span>Hungarian
</span>
<span>p + h = 5 equation 1
</span><span>190 p - 150 h = 370 equation 2
</span>
multiply eq. (1) by 150 (both sides) <span>
15 0p + 150 h = 750
190p -150 h = 370
add the two eqiations we get :
</span><span>190 p + 150p = 370 + 750
</span><span>
340 p = 1120
p= 1120/ 340 = 3.29
</span><span>3 minutes speaking Polish and 2 minutes speaking Hungarian.
</span>make sure if the number 370 ?? i think it is wrong , it can be 270 because i get a point in the answer

Answer:
<u>leg = √7 units (approximately 2.65 units)</u>
Step-by-step explanation:
Given a right isoceles triangle with a hypotenuse of 14 units, the two other legs must be congruent in length. Because this is a right triangle, the pythagorean theorem a^2 + b^2 = c^2, can be used.
Since the two legs are congruent, side a = side b. This means that
2leg^2 = hypotenuse.
