Answer:
Explanation:
-8 = (x + 11)/2
-8 • 2 = x + 11
-16 = x + 11
-16 - 11 = x
-27 = x
Or x = -27
Check:
-8 = (-27 + 11)/2
-8 = -16/2
-8 = -8
Therefore, x = -27
Step-by-step explanation:
![\frac{2}{3} x = - 10 \\ \frac{2x}{3} = - 10 \\ 2x = - 10 \times 3 \\ 2x = - 30 \\ x = \frac{ -30}{2} \\ x = - 15](https://tex.z-dn.net/?f=%20%5Cfrac%7B2%7D%7B3%7D%20x%20%3D%20%20-%2010%20%5C%5C%20%20%5Cfrac%7B2x%7D%7B3%7D%20%20%3D%20%20-%2010%20%5C%5C%202x%20%3D%20%20-%2010%20%5Ctimes%203%20%5C%5C%202x%20%3D%20%20-%2030%20%5C%5C%20x%20%3D%20%20%5Cfrac%7B%20-30%7D%7B2%7D%20%20%5C%5C%20x%20%3D%20%20-%2015)
Answer:
$9 per t-shirt
Step-by-step explanation:
First you subtract the cost of the hats from the TOTAL cost of the the T-shrits and the hat.
$83.00-$38.00= $45
Now that you just have the shirts WITHOUT the hat, which is why we subtracted the $38.00, we have to devide. You devide 45 by the number of shirts.
45/5=9
$9 per T-shirt.
Hope this helps
Answer:
(x+4)(x-3)
Step-by-step explanation:
x^2+x-12
This equation has the given solutions of -4,3
We have
<em>v</em> = (-7, 9) - (4, 3) = (-7 - 4, 9 - 3) = (-11, 6)
which as a linear combination of the <em>i</em> and <em>j</em> unit vectors is
<em>v</em> = -11<em>i</em> + 6<em>j</em>
