Answer:
Student 3
Step-by-step explanation:
Part of the 3-4-5 Pythagorean triples.
20 less than 1000 is the same thing as 1000 minus 20.
1000 minus 20 is 980.
20 less than 1000 is 980.
Y=x-4
x=y+4
y=-3(y+4)
y=-3y-12
4y=-12
y=-3
x=1
6 chewy toys and 6 cat collars are needed to have the same amount or price at both stores.
<h3>
Equation</h3>
An equation is an expression used to show the relationship between two or more angles and variables.
Let x represent the number of dogs and y represent the number of cats collars. Hence:
At Marco's market:
2x + 6y = 48 (1)
At Sonia's superstore:
4x + 4y = 48 (2)
Graphing both equations, the solution is at (6,6)
