Answer:

BC = 13

Step-by-step explanation:

AB + BC = AC, substitute values

4x + 2x - 3 = 45, that is

6x - 3 = 45 ( add 3 to both sides )

6x = 48 ( divide both sides by 6 )

x = 8

Hence

BC = 2x - 3 = (2 × 8) - 3 = 16 - 3 = 13

Liliana use for dark power crystals to raise 14 zombie soldiers she wants to know how many zombie soldiers Z she can race with 1
laiz [17]

Answer:

140 zombies

Step-by-step explanation:

Since this is a proportions problem and we are given three values and a variable we must solve for which is the number of zombie soldiers she can raise (z) with 10 dark power crystals. Therefore, we can use the rule of three to solve for this, in which we multiply the diagonal values and divide by the last remaining value in order to solve for the variable like so...

1 crystal <===>  14 zombies

10 crystals  <===>   Z zombies

(10 * 14) / 1 = 140 zombies
