Answer:
40
Step-by-step explanation: 40 x .45 = 18
X=-7 AB=-72
steps
since m is a midpoint, AM and MB are congruent so you set the two equations equal to each other, 4x-9=5x-3/3( is this a typo? bc 3/3 is 1)
subtract 4x from both sides m, -8=x-1
add 1 to both sides
x=-7
then plug -7 in for x 4(-7)-8=-36
since the two segments are congruent u do -36 x 2= -72

6×1,000×0.92=5,520
A=3
B=4
C=5
Substitute 3 in for 'a' in the equation, and 5 in for 'c' in the equation to get 17.
