Vlada [557]

Answer:

lenght = 2x + 3

breadth = x - 1

perimeter = 40

Now,

perimeter = 2(l+b)

40= 2( 2x + 3 + x - 1)

40= 2(3x - 2)

40 = 6x- 4

40+4 =6x

44/6 =x

x = 7.33

Omari and his two cousins received the same amount of money to go to the movies. Each boy spent $15. Afterward, the boys had $30

Jlenok [28]

Answer:

Each boy recieved $25.25 each

Step-by-step explanation:

First, you add up all the money the 3 boys spent.

15+15+15=45

Then you add the sum of the equation to the amount all the boys had afterward.

45+30.75=75.75

Finally, you divide that product to 3 boys.

75.75/3=25.25

Therfore the answer is $25.25 each.
