2x + y = 350
x + 2y = 475
3x + 3y = 825
x + y = 275
x = 275 - y
(plug back into first equation)
2(275 - y) + y = 350
550 - 2y + y = 350
550 - y = 350
-y =-200 or y = $200 (dog)
therefore, x = $75 (cats)
Check
2(75) + 200 = 350
75 + 400 = 475
HAPPINESS! :)
Answer:
x = 75 degrees
Step-by-step explanation:
180 - 125 = 55
50 + 55 = 105
180 - 105 = 75
Angles 8 and 15 are supplementary.
Answer:
x=2
Step-by-step explanation:
Since the points (2,4) and (2,7) are on the line whose equation is x = 2,
The equation of the line passing through them is hence x = 2
