Answer: 108 pancakes
Step-by-step explanation:
if you make 20 pancakes with 1 and 2/3 of flour,
with 9 cups you will make
(20*9)/ 1 &2/3
1 2/3= 5/3 we enter the whole in the fraction
(180)/(5/3)= 180*3/5=108 pancakes
Hey there!
Basically it wants you to add 3 and 8 from each other, what ever the answer to that part, you multiply the result by 9
Here this is what i meant
![3 + 8 = 11 \\ 11 ( 9) = 99](https://tex.z-dn.net/?f=%203%20%2B%208%20%3D%2011%20%5C%5C%2011%20%28%209%29%20%3D%2099%20%20)
Or you could do this method too!
![(3 +8) (9) \\ \\ 3 + 8 = 11 \\ 11(9) \\ = 99](https://tex.z-dn.net/?f=%20%283%20%2B8%29%20%289%29%20%5C%5C%20%5C%5C%203%20%2B%208%20%3D%2011%20%5C%5C%2011%289%29%20%5C%5C%20%3D%2099%20%20%20)
They both give you the result of ![99](https://tex.z-dn.net/?f=%2099%20%20)
So, I am assuming your expression would look like this: ![(3 + 8) * 9](https://tex.z-dn.net/?f=%20%283%20%2B%208%29%20%2A%209%20)
Good luck on your assignment and enjoy your day!

Answer:
x=4, y=2
Step-by-step explanation:
2x - y = 6
x + y = 6
Add these together to eliminate y
2x - y = 6
x + y = 6
-----------------
3x = 12
Divide by 3
3x/3 = 12/3
x=4
But we still need y
x+y =6
4+y =6
Subtract 4 from each side
4+y-4 = 6-4
y=2
Answer:
The answer is x = -7.7 ans x = -1.3
