Answer:
A. x + y = 34; 10x + 15y = 410
Step-by-step explanation:
Jody's total hours will be the sum of the hours spent on each job:
x + y = 34 . . . . . total hours
Jody's total earnings will be the sum of the earnings from each job:
10x +15y = 410 . . . total earnings
So, the system of equations is ...
- x + y = 34
- 10x + 15y = 410
A quadrilateral is a shape with 4 sides, regardless of their lengths, angles, or symmetry.
Therefore, a square is always a quadrilateral.
Answer:
Online Ordering is better.
Step-by-step explanation:
So you now that you save 20% if you to physical store and you save $20 if you go to the online store.

x−3y=9;−x+3y=−9
x−3y=9
−x+3y=−9
Add these equations to eliminate x:
0=0
