Okay so you want to do the parentheses first okay? So 2.3333...+1.3333333 is?3.666 or 3 2/3. So you got that right? So then 5 1/3+ 3 2/3. You get an easy 9. Because 1/3+ 2/3 adds up to 3/3, and is normally written as 1. So add a one to 5+3=8+1.

Use order of operations, by starting with the parenthesis first. 2 1/3 + 1 1/3 = 3 2/3. Then you would have to finish the rest of the problem by adding 5 1/3 to 3 2/3. Answer: 9

hey the question is, " The length of a rectangle is twice its width. The perimeter of the rectangle is 126 feet."​
Tema [17]

Answer:

42 = <em>l</em>

21 = <em>w</em>

Step-by-step explanation:

{l = 2<em>w</em>

{126 = 2<em>w</em> + 2<em>l</em>

126 = 2<em>w</em> + 2[2<em>w</em>]

126 = 2<em>w</em> + 4<em>w</em>

126 = 6<em>w</em>

21 = w [Plug this back into both equations to get the length of 42]; 42 = <em>l</em>

Robert is a high school basketball player. In a particular game, he made some three point shots and some free throws (worth one
Oksanka [162]

Answer:

let t = number of three-point shots

let f = number of free throw shots

Step-by-step explanation:

t + f = 9      (he made a total of 9 shots altogether)

3t + 1f = 23   (number of shots multiplied by their point value)

substitution method:   t = 9 - f

                                    3(9 - f) + f = 23

                                     27 - 3f + f = 23

                                      -2f = -4

                                         f = 2

find 't':                               t + 2 = 9

                                         t = 7
