Answer:
9/10
Step-by-step explanation:
2 2/5 - 1 1/2
Get a common denominator of 10
2 2/5 *2/2 = 2 4/10
1 1/2 *5/5 = 1 5/10
2 4/10 - 1 5/10
Borrow from the 2 as 10/10
1 + 10/10 +4/10 - 1 5/10
1 14/10 - 1 5/10
9/10

2. 6x=180
180/6= 30
x=30

2x 3.14 x 8.1 = 50.22in
Step-by-step explanation:
-10x + 4 = -7x - 14 - 7x - 14
-10x + 4 = -14x - 28
4x = -32
x = -8.
