The equation to describe the situation is 8p = 56
The number of packs of hot dog the neighbour bought is 7
p = number of packs of hot dogs
8 hot dogs are in each pack of hot dogs.
Altogether, they have 56 hot dogs. Therefore,
The equation to describe the situation is as follows:
The number of packs the neighbour bought can be calculated as follows:
<h3>Equation model:</h3>8p = 56
divide both sides by 8
8p / 8 = 56 / 8
p = 7

X = the number of months the tire was used
y = the thickness of the tire tread
y = -(3/7)x + 20
Substitute x for 20 (the number of months the tire was used) and solve for y.
The next question: Substitute x for 49 (the number of months the tire was used) and solve for y.
Answer:
yes it is linear equation in two variable
Answers and work shown in attachment! :)
Answer:
(-1, 1), (-1, 2), (0, 1)
Step-by-step explanation:
It appears as though letter designations have become confused. If not, your question answers itself, as a, b, c are given and you're asking for a, b, and c.
___
Reflecting the given points across the line y=-x transforms them like this:
(x, y) ⇒ (-y, -x)
That is, you swap the coordinates and negate them both. The result will be as shown above and in the attachment.
