4 ( 3x + 2x + 6 ) = 4 ( 5x + 6 ) = 4 ( 5x ) + 4 ( 6 ) = 20x + 24
Answer:
a = Yes, because 3/4 can be written as 6/8 and 6/8 minus 1/8 is 5/8ths which is greater then 1/2.
b = Kelly used 1/8 more than 1/2 of the tank. : )
A ratio of 2:3 is the same as 2/3 now we can divide out 2/3 to .6666666 and then multiply by 10 to get 6.666666 or you could just multiply 10 x 2/3 to get 20/3 and then divide to get 6.66666.
1. 2^2=4
Sqrt(2) ≈1.4
4+1.4=5.4
2. -2^2 = -4
Sqrt(-2) = -1.4 i -> 1
3. 3x + 2 = 14
3x=12
X= 4
