Hunter-Best [27]

Answer:

33 feet

22 feet

Step-by-step explanation:

Let the longer piece be x

Therefore the shorter piece is (2/3)x

x + (2/3)x  = 55                  Combine the left 2 terms.

(3/3)x + (2/3)x = 55           Add  

(5/3)x = 55                        Multiply both sides by (3/5)

(3/5) * (5/3)x = (3/5)*55

x = 33

The larger piece is 33 feet

The smaller piece is (2/3) * 33 = 22 feet

I need help. i don’t understand this question .

So the question is asking to solve for y

You know RS=7y-4

You know ST=y+5

You know RT=28

RS+ST=RT as shown in the diagram, This means that you can use that equation and replace RS,ST, and RT with what you know they are equal too. So you end up with the equation:

(7y-4)+(y+5)=28, Now you have to solve for y

7y-4+y+5=28

8y+1=28

8y=27

y=3.375
