The answer would have to be 52/87. Since it says "given", as in a geometric sense (proof), you know that the overall would have to be 87. It also adds that the students would be in the 10th grade, thus bringing us to the conclusion that 52/87 is correct. Then, simply use a calculator and put in 52/87. You're final answer, rounded to the nearest hundredth, should be 0.60.

Simplify the expression (2x − 9)(x + 6)

kenny6666 [7]

Answer:

Simplified form of given expression (2x – 9 )( x + 6 ) is $2 \mathrm{x}^{2}+3 \mathrm{x}-54$

Solution:

We need to simplify following expression.

(2x – 9) ( x + 6)

For sake of simplicity lets first assume 2x – 9 = A

So expression becomes A(x+6)

= Ax + A6

Now replace A by 2x – 9

= (2x – 9 ) x + (2x – 9 ) 6

$=2 \mathrm{x}^{2}-9 \mathrm{x}+12 \mathrm{x}-54$

On simplification, we get

$=2 \mathrm{x}^{2}+3 \mathrm{x}-54$

Hence simplified form of given expression (2x – 9 )( x + 6 ) is $= 2 \mathrm{x}^{2}+3 \mathrm{x}-54$

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

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.
