Answer:   D) 50 + 31.5x

<u>Step-by-step explanation:</u>

The expression for less than 7 days is 50 + 35x.

7 or more days has a 10% discount on the daily rate (35):

35 - 35(0.10)   =   35 - 3.5  =   31.5

So, the new expression is: 50 + 31.5x

omeli [17]

Answer:

x=45.5

Step-by-step explanation:

so 3x - 11+x+8+x-8+2x+7+x=360°

or 8x-4=360

or, x=364÷8

7 2\3+ (5 1\6-1 5\9)
lorasvet [3.4K]
Start off with: 5 1/6 - 1 5/9
turn it into an entire fraction: 31/6 - 14/9
make a common denominator (which is 18): 93/18 - 28/18 = 93 - 28 = 65/18
65/18 + 7 2/3 is the new equation
7 2/3 = 23/3
23/3 = 138/18
65/18 + 138/18 = 203/18
Simplify: 203/18 = 11 5/18
Answer: 11 5/18
