Please help me if you can

1. 1/2(5)(2) = 5 yd squared

2. 1/2(6)(8) = 24 ft squared

3. 1/2(12.4)(18) = 111.6 cm squared

4. 1/2(3.5)(6) = 10.5 m squared

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!

its 4 because 2 times 2 is 4, if you double the number two you get four
