Answer:
x = 8
Step-by-step explanation:
0.4x - 1.2 = 0.15x + 0.8
0.4x - 1.2 + 1.2 = 0.4x
0.15x + 0.8 + 1.2 = 0.15x + 2
0.4x = 0.15x + 2
0.4x - 0.15x = 0.25x
0.15x + 2 - 0.15x = 2
0.25x = 2
0.25x / 0.25 = x
2 / 0.25 = 8
x = 8
Answer:
70, 105, 140
Step-by-step explanation:
Answer:
Perpendicular.
Step-by-step explanation:
4x - 7y = 9 ---> 7y = 4x - 9 ---> y = 4/7 x - 9/7, slope= 4/7
7x + 4y = 5 ---> 4y = - 7x + 5 ---> y = - 7/4 x + 5/4, slope = - 7/4
lopes are negative-reciprocal , so these lines are perpendicular.
