The sum of two numbers is at least 30 and the difference between the two numbers is less than 8. X and y are the two numbers suc
vaieri [72.5K]

Answer:

1 Expert Answer

Let x and y be the two numbers. Then by assumptions we have x+y=30 and x-y=20. Hence, y=x-20 and by plugging this into the first equation we obtain x+x-20=30 or 2x=50 or x=25 and y=5

Step-by-step explanation:

So, divide 30 by 2 . That gives you 15 for x, 15 for y. Now, you have difference of six, divide by two, that equals 3.

Answer:

<em>Part A:  3,</em>

<em>Part B:  - 4</em>

Step-by-step explanation:

<em>~ Part A ~ </em>

The problem would be in terms of such an expression: ( - 6 - ( - 3 )^2 )/ -5

Now knowing the expression, let us simplify in terms of basic algebra:

( -6 - 9 )/ -5 = ( - 15/ - 5 ) = <em>Answer; 3</em>

<em>~ Part B ~ </em>

We know the problem to be p^2/ r, but we must substitute the value of p being -10, and r ⇒ -25: ( - 10 )^2/ -25

Now let us simplify the expressions:

( - 10 )^2/ -25 = 100/ - 25 =<em> Answer; -4</em>
