What’s the correct why to solve
Vaselesa [24]

x^2-y^2=2\\ \underline{x^2+y^2=4}\\\\ 2x^2=6\\ x^2=3\\ x=-\sqrt3 \vee x=\sqrt3\\\\ 3+y^2=4\\ y^2=1\\ y=-1 \vee y=1\\\\ x\in\{(-\sqrt3,-1),(-\sqrt3,1),(\sqrt3,-1),(\sqrt3,1)\}

So, there are 4 solutions.

If 6/10 is multiplied by a fraction less than 1,which of these would be an answer 6/10,1/2,3/2,or 5
Pavlova-9 [17]

If \frac{6}{10} is multiplied with a fraction less than 1, out of the given options \frac{1}{2} would be the answer.

Explanation:

  • First, we need to determine what a fraction lesser than 1 is. If the numerator is lesser than the denominator, the fraction will be lesser than 1 whereas if the denominator is higher than the numerator is would equal more than 1.
  • If \frac{6}{10} is multiplied with 1, we get the value \frac{6}{10}. Since the fraction must be lesser than 1, \frac{6}{10} cannot be an answer. So option 1 cannot be the answer.
  • The value of \frac{6}{10} is 0.6. If it is multiplied with any value lesser than 1, the resulting value cannot be higher than the value of 0.6. The value of the fraction \frac{3}{2} is 1.5 and the value of 5 are both greater than 0.6. So the third and fourth options cannot be the answer. So \frac{1}{2} is the answer.
