Answer:
the first equation could be something along the lines of
then the second is 
Step-by-step explanation:
this is how shifting works
Given: Alonzo's suitcase can weigh no more than 20 kilograms if he wants to take it on the airplane without paying a fee.
Let x denote the weight of suitcase, then
We know that 1 kg =10 hg
Therefore, 20kg=
⇒
Since, the weight of his suitcase is 220 hg.
The amount of weight will Alanzo have to take out of his suitcase to meet the weight limit will be :-
Hence, 20 hg of weight have to take out of his suitcase to meet the weight limit.
Answer:
Not solutions.
Step-by-step explanation:
-5x+6y=-5
6y=-5+5x
6y=5x-5
y=5/6x-5/6
-5/6 is about -0.833
And the slope is 5/6.
So for every x there is 5/6y.
This means (1, 4) won't work cause it's too low.
Also 5/6*6=5. this is too low too.
So they aren't solutions.
She has 10 liters left. Find 4/9 of 18 by multiplying 4/9 and 18. 4/9 of 18 is 8, so she served 8 of the 18, leaving 10 liters.
