Answer:
(4,3)
Step-by-step explanation:
2y = x + 2
x - 3y = -5
Rearrange the second equation to equal y.
x - 3y = -5
x + 5 = 3y
(x+5)/3 = y
Substitute into the first equation.
2y = x +2
2[(x+5)/3] = x + 2
(2x + 10)/3 = x + 2
2x + 10 = 3(x + 2)
2x + 10 = 3x + 6
10 - 6 = 3x - 2x
4 = x
Therefore, the correct ordered pair is (4,3) since x is equal to 4.
Asuming they started summer at the same time. The logical answer will be none, because it will take at least 165 days for the lcd(5) to overlap and there is not 165 days in a summer.
so it will be a rate of 1 for every 5 times Antonia went to the beach.
Answer:
2 :)
Step-by-step explanation:
let's say you have 1 apple, if you add another apple to the pile, you will have 2 apples
if you remove the apples at the end, you get the equation 1 + 1, and now you know 1 + 1 = 2
If there is 5/8 of a total fuel supply on board, the ship can make 6 round trips
<u>Solution:</u>
Let the number of the round trips the ships make be "n"
Now, according to question in one trip the ship consumes 
of its total fuel supply which is given to be 
Fuel supply used in "1" trip = 
Now fuel supply used for "n" trip is given as:
Hence the ship can make 6 round trips
Both graphs A and B are linear. In both graphs, the y value is going up at a constant rate in comparison to their x values. For example, in graph A every time the x value is increased by 1 the y value is increased by 2 values showing that they have the same gradient. For a graph to be linear it must have a constant rate of increase or decrease.
