The larger of the two positive numbers is 8 more than the smaller. The sum of their squares is 104. Find the two numbers.
poizon [28]

Hey there!

Let's set up a system of equations to find our answer. We will use x and y, with y being the larger 1.

y=x+8

x²+y²=104

We plug our value for y into the second equation and we get that y is equal to two. We can then plug this into the first equation and we get 10.

Our two numbers are two and ten.

I hope this helps!

Let's plug our y value into the second equation.

x²+x²+64=104

. An urn contains 6 blue and 5 red marbles. Reach in and grab one marble and then another (without replacing the first one). Wha
natima [27]

Probability that you have chosen 2 red marbles is 3/11

<h2>How to solve?</h2>

Total number of marbles = 6 + 5 = 11

Number of red marbles = 6

Number of blue marbles = 5

Important Points:

1. Replacement is not allowed

2. Blue is followed by Red

Probability has been introduced in Maths to predict how likely events are to happen. The meaning of probability is basically the extent to which something is likely to happen.

Probability of Blue first = 5/11

Probability of Red second = 6/10 (one marble is already taken out)

Probability = 5/11 * 6/10 = 3/11
