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.
You divide $4.55 by 7.
$0.65 times 9 = $5.85
Answer: A.82
have: x + 105 + x + 89 = 180
⇔ 2x + 194 = 180
⇔ 2x = 180 - 194 = -14
⇔ x = -14/2 = -7
=> the measure of the angle is -7 + 89 = 82
Step-by-step explanation:
1/3x + 2 = 4/3x - 5
2 + 5 = 4/3x - 1/3x
7 = x
y = 1/3(7) + 2
y = 7/3 + 2
y = 7/3 + 6/3
y = 13/3
solution is : (7,13/3) <=
Number 6
The answer is 0.8
