What is 18x-9(x-1)=5(3x+3)

-4

Step-by-step explanation:

18x - 9(x - 1) = 5(3x + 3)

Step 1: Distribute

18x - 9x - 9 = 15x + 15

Step 2: Combine like terms

9x - 9 = 15x + 15

Step 3: Solve by using opposites terms, try to get x on one side and the solution on the opposite side

9x - 9 = 15x + 15

-9x        -9x

-9 = 6x + 15

-15         -15

-24 = 6x

/6      /6

-4 = x

$15 each

step-by-step explanation:

$45/3 children= $15 each

answer: the angel abc is 30°,and the abc is a triangle where the angel bac is 90°

so ac is the half of 24=12ft,and from the pythagorean theorem we find ba

ba=√bc^2-ac^2=√576-144=√432=12√3ft

so bac is 12+12√3=12(1+√3)ft
