She is correct because a negative subtracted by a negative is positive.
Answer:
The GCF is -10
Step-by-step explanation:
-10 in the highest/largest number that goes into both -20 and -50.
if you have to factor -20v-50 as well it would be:
-10(2v+5)
and to check if that answer is correct, distribute -10 inside the parenthesses:
-10 times 2v = -20v
-10 times 5 = -50
-20v-50
6 chewy toys and 6 cat collars are needed to have the same amount or price at both stores.

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)
