Answer:

Multiply by 3 -> 3(x - y = 6)

Step-by-step explanation:

Cuz since the 2nd is positive 3y

u need a negative 3y to get rid of it

3(x - y = 6)

2x + 3y = 7

3x - 3y = 18

2x + 3y = 7

5x/5 = 25/5

x = 5

5 - y = 6

-5          -5

-y/-1= 1/-1

y = -1

(5,-1)

forsale [732]

Answer:

  • n < 18
  • n ≥ 15

Step-by-step explanation:

The wording "fewer than" is translated to the math symbol "less than". The variable n represents the number of students.

  <em>the number of students</em> is fewer than 18

translates to ...

__

The wording "at least" translates to the math symbol "greater than or equal to."

Use the babylonian method to approximate square root of 24 to the nearest hundredth.
irina [24]
We will start with our guess of 12, since 12*2 = 24.
Divide 24 by 12; 24/12=2.  Average this answer with our guess:  (12+2)/2=7.  This is our new guess.
24/7=3.428571429.  Average this with our guess of 7:  (3.428571429+7)/2=5.214285715.  This is our new guess.
24/5.214285715=4.602739726.  Averaging with our guess:  (4.602739726+5.214285715)/2=4.90851272.  New guess!
24/4.90851272=4.889464766.  Averaging with our guess:  (4.889464766+4.90851272)/2=4.898988743.  New guess!  You can see as we go through our guesses are closer and closer to the same number...)
24/4.898988743=4.898970228.  Averaging:  (4.898970228+4.898988743)/2=4.898979486.  At this point our answer is the same every time down to the hundred-thousandth.  Our estimate to the nearest hundredth would be 4.90.
