I’m confused can someone help me

1. This equation of m<a + m<c = m<b - m<c wouldn't be correct unless the measure of angle c was 0. So technically there is no statment to make that equation true.

2. Angle addition postulate.

3. Transitive property of equality.  

4. Substitution property.

Step-by-step explanation:

You might want to recheck and see if these are the correct answer they seem to be to me. Im only in 10th grade so i kind of just learned this.

If you have any questions feel free to ask in the comments - Mark

tickets for the harlem globetrotters

show at michigan state university in

2010 cost $16, $23, or, for vip seats, $40.

total revenue = 16x + 23y + 40z

if 9 times as many $16 tickets were sold

as vip tickets,

x = 9z => x – 9z = 0, if 9 times as many $16 tickets were sold

as vip tickets,

x = 9z => x – 9z = 0, sales of all three kinds of tickets would

total $46,575.

16x + 23y + 40z = 46575, how many of each kind of ticket would

have been sold?

solve for x, y and z

x − 9z = 0

x − y − z = 55

16x + 23y + 40z = 46575

x = 1170

y = 985

z = 130

welcome!
