Answer: i think its $.13
Step-by-step explanation:
12x - 11y = 75 . . . . . . . . (1)
5x - 11y = 89 . . . . . . . . (2)
(1) - (2): 7x = -14
x = -2
From (1): 12(-2) - 11y = 75
-24 - 11y = 75
-11y = 75 + 24 = 99
y = -9
Therefore, x = -2 and y = -9
Answer:
The number of red marbles in the bag are 114.

Step-by-step explanation:
(−4)−(−2)–{(−5)–[(−7)+(−3)–(−8)]}
PEMDAS
Work from the inside out
Change subtracting negatives to adding
(−4)+2–{(−5)–[(−7)+(−3)+8)]}
(−4)+2–{(−5)–[(-2)]}
(−4)+2–{-5+2}
(−4)+2–(−3)
Changing to adding
(−4)+2+3
-2+3
