M∠LON=77 ∘ m, angle, L, O, N, equals, 77, degrees \qquad m \angle LOM = 9x + 44^\circm∠LOM=9x+44 ∘ m, angle, L, O, M, equals, 9,
timama [110]

Answer:

Step-by-step explanation:

Given

<LON = 77°

<LOM = (9x+44)°

<MON = (6x+3)°

The addition postulate is true for the given angles since tey have a common point O:

<LON = <LOM+<MON

Since we are not told what to find we can as well look for the value of x, <LOM and <MON

Substitute the given parameters and get x

77 = 9x+44+6x+3

77 = 15x+47

77-47 = 15x

30 = 15x

x = 30/15

x = 2

Get <LOM:

<LOM = 9x+44

<LOM = 9(2)+44

<LOM = 18+44

<LOM = 62°

Get <MON:

<MON = 6x+3

<MON = 6(2)+3

<MON = 12+3

<MON = 15°

I'm not really sure, because 650 marked down by 27% would be 474.5, which is close but not exact.

Hope I helped a little bit, sorry if I'm wrong.

Candice bought 3 shirts each shirt cost the same amount and was discounted by $3.66 Candice paid a total of $62.31 before tax. H
omeli [17]

Answer:

Step-by-step explanation:

Let the cost of each shirt be x.

Would assume each  shirt was discounted by 3.66

Amount to be paid for each :    x - 3.66

Total =    3*(x - 3.66)

3*(x - 3.66) = 62.31

x - 3.66 = 62.31/3

x - 3.66 =  20.77

x = 20.77 + 3.66

x = 24.43

Each shirt cost $24.43  before the discount.
