Hi there!
To solve both of you questions, you will need to use the cross product method :
<u>Finding "x" :</u>
So you have to do :
(4 × 
) ÷ 2 = x gallon
4 times is the same thing as 4 times 0.5, which equals 2.
2 ÷ 2 = x gallon
1 = x gallon
So the amout for x would be : 1 gallon
<u>Finding "y" :</u>
You could do the exact same method as we did for finding "x", but the easiest and fastest way to get our answer is just by multiplying the amout we got for "x" by 2 because we are putting 8 scoops instead of 4 for "x" (and 4 times 2 = 8) :
1 gallon × 2 = y
2 gallons = y
So your answer is : The amount for y would be : 2 gallons
There you go! I really hope this helped, if there's anything just let me know! :)
Answer:
(2,1)
Step-by-step explanation:
You want to write this equation in the form (x+...)(x+...) (maybe with a minus sign). To do this, find numbers that, when multiplied, give 16, and when added give -10.
What whole numbers give 16?
1*16 and -1*-16
2*8 and -2*-8
4*4 and -4*-4
Which of these solutions, when changed into a sum, give -10?
Try them one by one and find it is:
-2-8 = -10.
So (x-2)(x-8) is the factorization!
This is really a bit of trial and error, but since most of the time the assignments deals with whole numbers, there aren't that many possibilities.
Negative numbers can be integers. Only irrational can't be integers. If it can be written as a ratio then it's an integer.
