Answer:
x=-5, y=2. (-5, 2).
Step-by-step explanation:
2x+y=-8
3x-5y=-25
------------------
5(2x+y)=5(-8)
3x-5y=-25
-------------------
10x+5y=-40
3x-5y=-25
--------------------
13x=-65
x=-65/13
x=-5
2(-5)+y=-8
-10+y=-8
y=-8-(-10)=-8+10=2
This involves a bit of logic in thinking about what LCM actually means.
LCM is the least common multiple. A
common multiple is a multiple shared by two or more numbers. And by
multiple, we mean some number multiplied by successive integers; this set contains multiples of 5 {5, 10, 15, 20, 25...}. You can see that the least (or lowest) common multiple is the lowest multiple shared by two numbers. Like for 6 and 9, you have {6, 12,
18, 24...} and {9,
18...}, so LCM(6,9) = 18.
Now, if an LCM must be shared by both numbers, and to get a multiple of the largest number, you have to multiply by an integer greater than or equal to 1, then the LCM of two numbers can never be less than the larger of the twi numbers. Generally, if x and y are positive real numbers, and x is greater than y,

From the information given, each batch of cookies requires 1/6 of a bag of flour.
So how many batches can be gotten from 5/6 of the bag of flour?
We form an equation
1batch = 1/6
x batches = 5/6
Where x is the number of batches from 5/6 bag of flour.
Cross multiplying this equation we get:
x * 1/6 = 1 * 5/6
simplify it:
x * 0.16 = 1 * 0.83
x = 1 * 0.83 / 0.16
x = 0.83 / 0.16
x = 5.2
Therefore factory made approximately 5 batches of cookies yesterday.
.79 tons equals out to 1,580 pounds . Hope this helps :)
Answer:Domain: all x-values that are to be used (independent values).
Step-by-step explanation:The domain is the set of all first elements of ordered pairs (x-coordinates). The range is the set of all second elements of ordered pairs (y-coordinates). Only the elements "used" by the relation or function constitute the range. Domain: all x-values that are to be used (independent values).
