Answer:
1)  x > -12
Step-by-step explanation:
first, subtract 7 from each side of the inequality to get:
-2/3x < 8
multiply each side by the reciprocal of -2/3 which is -3/2 to get:
x > -24/2
notice the symbol has been reversed because that is the rule whenever you multiply or divide an equality be a negative value
simplified, answer is x > -12

Answer:
B!
Step-by-step explanation:
we know that (x-5) and (y-6) must add up to 129 because 180-51 is 129
now let's plug in the values to see
51-5= 66 63-6 = 57 
57+66 is 123, not this one, let's repeat the same step
77-5 is 72, 63-6 is 57, these added is 129
