Answer:
ABC = 27
DBC = 56
Step-by-step explanation:
ABC + CBD = ABD
x+10 + 4x-12 = 83
Combine like terms
5x -2 = 83
Add 2 to each side
5x-2+2 = 83+2
5x = 85
Divide each side by 5
5x/5 = 85/5
x =17
ABC = x+10 = 17+10 = 27
DBC = 4x-12 = 4*17 -12 = 68-12 = 56

Answer:
3x8= 24sf
5x7= 35sf
9x10= 90sf
13x2= 26sf
8x8= 64sf
Step-by-step explanation:
Solve for x by simplifying both sides of the equation, and then isolating the variable.
10. x = -1
12. x = 23/19
