If you would like to calculate 6/(x+1)-5/2=6/(3x+3), you can do this using the following steps:
6/(x+1)-5/2=6/(3x+3)
6/(x+1)-5/2=6/(3(x+1)) /*(x+1)
6 - 5/2 * (x+1) = 6/3
6 - 2 = 5/2 * (x+1)
4 = 5/2 * (x+1) /*2/5
4 * 2/5 = x + 1
8/5 - 1 = x
x = 8/5 - 5/5 = 3/5
The correct result would be 3/5.
Should be true. The coffee would not stay the same temperature as it was originally than it would over time.
Answer:
9 : 7
Step-by-step explanation:
Given
4.5 : 3 ( multiply both parts by 2 to clear the fractions )
= 9 : 7
Distribute 1/4 by multiplying it by 8, -6X and 20 you end up with
1/4times8=2
1/4times-6x= -1.5x
1/4times20=5
so 2-1.5x+5
add 2 and 5 to get 7
the answer is -1.5x+7
