I don't know what you mean by "Broken apart," but I'll do my best...
20 x 90 = 1800
9 x 7 = 63
1800 + 63 = 1863
I hope this helped you! :)
2. You would use liters for a bathtub.
3.You would use milliliters for a medicine capsule.
<u>Answer:</u>
or ![f(7)=-1.67](https://tex.z-dn.net/?f=f%287%29%3D-1.67)
<u>Step-by-step explanation:</u>
We are given the following function of x and we are to find the value of
:
![f ( x ) = \frac { 3 } { x + 2 } - \sqrt { x - 3 }](https://tex.z-dn.net/?f=%20f%20%28%20x%20%29%20%3D%20%5Cfrac%20%7B%203%20%7D%20%7B%20x%20%2B%202%20%7D%20-%20%5Csqrt%20%7B%20x%20-%203%20%7D%20)
Substituting the given value (7) in the above function to get:
![f(x)=\frac{3}{x+2}-\sqrt{x-3}](https://tex.z-dn.net/?f=f%28x%29%3D%5Cfrac%7B3%7D%7Bx%2B2%7D-%5Csqrt%7Bx-3%7D)
![f ( 7 )= \ frac{3}{7+2}-\sqrt{7-3}](https://tex.z-dn.net/?f=%20f%20%28%207%20%29%3D%20%5C%20frac%7B3%7D%7B7%2B2%7D-%5Csqrt%7B7-3%7D)
![f(7) = \frac { 3 } { 9 } - \sqrt { 4 }](https://tex.z-dn.net/?f=%20f%287%29%20%3D%20%5Cfrac%20%7B%203%20%7D%20%7B%209%20%7D%20-%20%5Csqrt%20%7B%204%20%7D%20)
![f(7)=\frac{1}{3}-2](https://tex.z-dn.net/?f=f%287%29%3D%5Cfrac%7B1%7D%7B3%7D-2)
![f(7)=\frac{1}{3}-\frac{6}{3}](https://tex.z-dn.net/?f=f%287%29%3D%5Cfrac%7B1%7D%7B3%7D-%5Cfrac%7B6%7D%7B3%7D)
or ![f(7)=-1.67](https://tex.z-dn.net/?f=f%287%29%3D-1.67)
A − 3b = 16
a = b − 2
b - 2 - 3b = 16
2b = - 18
b = - 9
a = - 9 - 2
a = - 11
(-11,-9)
