Answer:
x = 11
Step-by-step explanation:
(0.3x - 2.1)/3 = 0.4
0.3x - 2.1 = 0.4 * 3
0.3x - 2.1 = 1.2
0.3x = 1.2 + 2.1
0.3x = 3.3
x = 3.3/0.3
x = 11

Answer:
65
Step-by-step explanation:
just to sum all the given measurements:
19+31+15=65.
2/3a - 2 = 1/3
2/3a = 2 + 1/3
2/3a = 7/3
a = (7/3) / (2/3)
a = (7/3) * (3/2)
a = 21/6
a = 7/2 ---- that is the answer
