Answer:
first get a common denominator by multiplying 7 and 4 to get 28
28 is our common denominator here.
Step-by-step explanation:
We want to add the fractions 2/7 and 1/4
(2/7) * (4/4) and (1/4) * (7/7)
(2/7) * (4/4) + (1/4) * (7/7) = 8/28 + 7/28 = 15/28
2t + 8 ≥ -4(t+1)
PEMDAS
2t + 8 ≥ -4t - 4
2t + 12 ≥ -4t
12 ≥ -6t
-2 ≤ t
