3x+8x+2=-3
11x=-3-2
11x=-5
x=-5/11
y=4(-5/11)+1
y=-20/11+11/11
y=-9/11
+6 ; 45,51
+ evens; 40,52
X -2; -64, 128
+ reducing squares 63+1/4, 63 +13/36

Step-by-step explanation:
Randy first won 12 points on Monday. He earned as twice as many on Tuesday.
12 * 2 = 24
Randy scored 24 points Tuesday.
Randy earned 3 more points than Tuesday's points the next day.
24 + 3 = 27
Randy earned 27 points Wednesday.
12 + 24 + 27 = 63
Randy should earn a total of 63 points for the 3 days.

Answer:
B. 12/13
Step-by-step explanation:
The answer choices suggest that you intend the problem to be interpreted as ...
(8/13)/(2/3) . . . . . parentheses are required
= (8/13) × (3/2) = (8·3)/(13·2) = (8·3)/(2·13)
= (8/2) × (3/13) . . . . making use of the associative property
= 4 × 3/13 = 12/13
