3(x+2)=7 X=1/3 Because 3(x+2) would simplify to 3x+6=7 and then its a two-step equation
Answer:
1/6
Step-by-step explanation:
It is a 6 sided die, so you have 6 possibilities, so that is going to be you denominator.
There is only one number 2 on the die, so you have 1 as your numerator.

The value of x is 5, if a, b, and c are collinear points.
According to the given question.
a, b, and c are collinear points.
Which means points a, b, and c both lie in a same line.
b is between a nd c .
Also, ab = 12
bc = 5x - 2
and ac = 3x + 20
Since, b lies in between a and c
Therefore,
ab + bc = ac
12 + 5x - 2 = 3x + 20
⇒ 10 + 5x = 3x + 20
⇒ 5x - 3x = 20 - 10
⇒ 2x = 10
⇒ x = 10/ 2
⇒ x = 5
Therefore, the value of x is 5.
