Answers

Answer:

x= -3

Step-by-step explanation:

Distribute 4(2-4x) which leaves you with 8-16x-3x=65

combine the like terms which leaves you with 8-19x=65

subtract 8 from both sides 8-19x-8=65-8 which leaves you with -19x=57

lastly divide -19 from both sides which leaves you with x= -3

See Explanation

Step-by-step explanation:

The question is incomplete as the dimension of the prism is not given. However, the following steps can serve as a guide for you.

The volume of a rectangular prism is calculated as thus:

My favorite​ group, The​ Lumineers, is coming to Prescott and YC for a concert. Tickets are sold in three​ levels, $45,​ $65, and​ $95 depending on seats. The auditorium seats 1100 people total on the different​ levels; for them to come to YC we need to sell​ $66,500 worth of tickets and the auditorium has as many cheap​ ($45) tickets as the sum of the other two levels​ ($65 and​ $95).

Answers

Answer:

550 $45 tickets, so $24750 worth of $45 tickets

Step-by-step explanation:

If $45 tickets=x, $65=y, and $95=z, then the question is saying x=y+z. And if x+y+z=1,100, then x=1100/2, so 550 $45 tickets. 550*45 is $24750
