Answer:

y = 6

Step-by-step explanation:

7x - 9y = 23

7(11) - 9y = 23

77 - 9y = 23 (subtract 77 from both sides)

-9y = -54 (divide both sides by -9)

y = 6

54=9y

54/9=y

54/9=6

y=6

4x - 3y + 20 = 0....4x - 3y = -21

4x - 3y = -21.....multiply by -2
5x - 6y = -25
----------------
-8x + 6y = 42 (result of multiplying by -2)
5x - 6y = -25
---------------add
-3x = 17
x = -17/3

Given that t<span>he mean lifespan of a sylvania light bulb is 1600 hours with a standard deviation of 300 hours, an iqr of 450 hours, and a range of 690 hours. the lifespan distribution is relatively symmetric.

Since, the distribution is relatively symmetric, the measure of spread that is the best measurement is the standard deviation.</span>

Slove the equation r+ 3 = (r - 5)<br><br> explain step by step please
grigory [225]

Answer:

no solutions

Step-by-step explanation:

<u>Solving</u>

Step 1: Subtract 3 from both sides.

  • r+3-r=r-5-r
  • 3=-5

Step 2: Subtract 3 from both sides.

  • 3-3=-5-3
  • 0\neq -8

Therefore, there are no solutions to this equation.

Have a lovely rest of your day/night, and good luck with your assignments! ♡

Maxi is trying to stack books on a shelf that is 18 inches tall. If the books are each 4/5 inch thick, how many can she stack?
kari74 [83]
I believe it should be 22½ or 22 books

You would need to divide 18 and ⅘

18 ÷ ⅘ = 22½

I hope this helps, even though I’m not totally sure :)
