Answer:

\displaystyle [9, 4\frac{1}{2}]

Step-by-step explanation:

I figure these exercises out by numeric association. I see a 3, so I know right away that there <em>might</em> be a 9 somewhere. So, you start by plugging 3 in for \displaystyle x, THEN plug \displaystyle 1\frac{1}{2} in for \displaystyle y sinse there are <em>twise</em><em> </em>the quantity of \displaystyle y than there are of \displaystyle x. Now, doing so will give you \displaystyle 24 ≠ 18. This tells you to try another pattern, so go with plugging \displaystyle 4\frac{1}{2} in for \displaystyle y and \displaystyle 9 in for \displaystyle x. Doing so gives you what you are looking -- \displaystyle 36 = 36. Therefore, the association wourked perfectly. ☑

I am joyous to assist you at any time.

Estimate the solution to the system of equations.
Leona [35]

Answer:

\sf C)  \  x = -1\dfrac{2}{5}  , \  y =  \ 1\dfrac{3}{5}

Given equations:

  • a) -3x + 3y = 9
  • b) 2x - 7y = -14

<u>Make x the subject in equation 1</u>:

  • -3x + 3y = 9
  • -3x = 9 - 3y
  • x = y - 3

<u>Substitute this into equation 2</u>:

2(y - 3) - 7y = -14

2y - 7y = -14 + 6

-5y = -8

  y = -8/-5

  y = 1.6

Then x = y - 3

           = 1.6 - 3

           = -1.4

Solution: (x, y) ⇒ (-1.4, 1.6)

Find a whole number between 9 4/9 and the square root of 144
postnew [5]
First, we'll want to write out the equation
9 \frac{4}{9} < n < \sqrt{144}

then reduce what we can
9 \frac{4}{9} < n < 12

so this means n can equal any whole number between 9 4/9 & 12, which gives us the options of {10,11}

n = 10 \: or \: 11
