Ugo [173]3 years ago
6 0

Answer: Ok for the first two they are true.

Step-by-step explanation: So how you would do this is simple, so for # 2 2x-5=11 (x) represents a number and you have to find it. So For this one put an eight in the x's place and that makes 2(8)-5=11 so when you see 2x that mean 2 times what ever x is. so 2x8=16, 16-5 =11.

Mr. Flowers 23 1/4 of land. He is going to 1/3 the acreage. He will sell the rest as 1/2-acrea lots. How many lots will he have
loris [4]

Answer:

  B.  31

Step-by-step explanation:

The acreage Mr. Flowers intends to sell is 2/3 of his total, so is ...

  (2/3)(23 1/4) = (2/3)(93/4) = 31/2 . . . . acres

Divided by 1/2 (which is the size of a lot), we will get the number of lots this will make:

  (31/2)/(1/2) = 31/1 = 31

Mr. Flowers will have 31 lots for sale.
