Answer:its the third one i took the test
Step-by-step explanation:
Answer:
x = -1/10 or -0.1
Step-by-step explanation:
-1.8 - 6x = 6(0.1 + 3x)
-1.8 - 6x = 0.6 + 18x
-6x - 18x = 0.6 + 1.8
-24x = 2.4
-x = 2.4/24
-x = 24/10 / 24
-x = 24/10 * 1/24
-x = 24/240
-x = 1/10
x = -0.1
Answer:
27 + 28 + 29 = 84
Step-by-step explanation:
x + (x+1) + (x+2) = 84
3x + 3 = 84
84 - 3 = 81
81 / 3 = 27
