Question

Can someone help? BC=6x-1, AB= 6, and. AC=1lx find BC

Answer 1

Answer:

BC = 5

Step-by-step explanation:

AB = 6

BC = 6x -1

AC = 11x

We know that AC is the same length as AB and BC combined. The way to finding the length of BC is by adding the values/equations of these segments and setting them equal to the equation of AC. Then, you can isolate the "x" variable. Finally, you can plug that answer into the BC equation to find the numerical value.

AB + BC = AC

(6) + (6x - 1) = 11x

6x + 5 = 11x

5 = 5x

x = 1

BC = 6x - 1

BC = 6(1) - 1

BC = 6 - 1

BC = 5
