3 0

Step-by-step explanation:

Solve by Subsitution

x = 50 - y

Replace this into the second equation

y(50 - y) = 300

50y -  {y}^{2}  = 300

Write in standard form

-  {y}^{2}  + 50y = 300

Use the quadratic formula, and our answer will be

(6.97,43.02)

(43.02,6.97)

√37 &lt; 5 1/4 (true or false)
Alex787 [66]
OK so on the top problem, the first thing you want to do is find the √37, once you know the answer to that you can compare it to 5 1/4 then it will be much easier to see is in fact √37 less than 5 1/4 or not.

On the bottom you want to know if 15 over the square root of ten is greater than 8.38 so what you want to do is to first find the square root of ten. after you know this then you put that number under 15. then you can compare what ever 15÷√10 is to 8.83. if you need any more info let me know.
