AB= 4x + 7 and BC = 20x - 5
AB ~= BC

Answer:
3/4
Step-by-step explanation:
Congruent segments have the same length, so:
[tex]AB= BC \\ \\ 4x+7=20x-5 \\ \\ 12=16x \\ \\ x=3/4[/tex]
The value of the variable x is 3/4
Congruent segment are segments with equal or congruent lengths.
From the information given, we have that line AB is approximately equal to line BC. This is represented as;
AB = BC
Where;
Now, let's equate the expressions
4x + 7 = 20x - 5
collect like terms
4x - 20x = - 5 - 7
- 16x = - 12
Make 'x' the subject of formula
x = -12/-16
x = 3/4
Thus, the value of the variable x is 3/4
