Answer:

  • smaller: -4
  • larger: -1

Step-by-step explanation:

Substituting the given variables into the word problem, we have two equations:

  3x +3y = -15

  6x -3y = -21

Adding these equations eliminates y:

  9x = -36

  x = -4 . . . . divide by 9

Using this in the first equation, we have ...

  3(-4) +3y = -15

  -4 +y = -5 . . . . . divide by 3

  y = -1 . . . . . . . . . add 4

The smaller number is -4; the larger is -1.

I need help to complete this question
Bezzdna [24]

The complete fractional question given in the above picture is 55/3 = 1 + 52/3 = 2 + 49/3 = 5 + 40/3 = 8 + 31/3 = 10 + 25/3

<h3>Fraction</h3>

Let

  • Each empty box = x

55/3 = 1 + x/3

55/3 = (3+x) / 3

55/3 × 3 = 3 + x

55 = 3 + x

55 - 3 = x

52 = x

55/3 = 2 + x/3

55/3 =(6+x) / 3

55/3 × 3 = 6+x

55 = 6 + x

55 - 6 = x

49 = x

55/3 = x + 40/3

55/3 = (3x+40) / 3

55/3 × 3 = 3x + 40

55 = 3x + 40

55 - 40 = 3x

15 = 3x

x = 15/3

x = 5

55/3 = x + 31/3

55/3 = (3x+31) / 3

55/3 × 3 = 3x + 31

55 = 3x + 31

55 - 31 = 3x

24 = 3x

x = 24/3

x = 8

55/3 = 10 + x/3

55/3 = (30+x) / 3

55/3 × 3 = 30 + x

55 = 30 + x

55 - 30 = x

25 = x

Help me with both questions <br>plz read carefully so you can help me
Scrat [10]

Answer:

2. Both

3. e = 3, f = -5, g = 2

Step-by-step explanation:

2. Order doesn't affect product

3. You get e • f = -15, e • g = 6, f • g = -10 from the problem.

   e = -15/f    (solve for e)

   (-15/f) • g = 6    (plug into second equation)

   (-15g/f) = 6    (multiply)

   -15g = 6f    (multiply)

   (-5g/2) = f    (divide)

   (-5g/2) • g = -10    (plug into last equation)

   (-5g^2)/2 = -10    (multiply)

   -5g^2 = -20    (mulitply)

   g^2 = 4    (divide)

   g = 2    (square root)

   e • g = 6    (plug in for g, solve for e)

   e • 2 = 6

   e = 3

   f • g = -10    (plug in for g, solve for f)

   f • 2 = -10

   f = -5

I don't know if your teacher made a typo because I tried this multiple times and got the same answer. I don't know how e is negative.
