3. Answer: a) RT

                   b) XZ

                   c) TS


4. Answer: a) 26

                  b) 58

                  c) 21.5

                  d) 127

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

2(PT) = AE              2(CP) = AN                 2(CT) = EN

2(13) = AE               2(29) = AN                  2(CT) = 43

  26 = AE                  58  = AN                      CT  = 21.5


Perimeter = AE + AN + EN

                = 26 + 58 + 43

                = 127

You should then rewrite it as 5,600÷80=x

Now simplify.

x=70

Please help somebody
Dmitry [639]

Answer:

C

Step-by-step explanation:

ok so, assuming that b cannot equal 0, we can divide it on both sides

(3a - 5)/c = b/b

anything divided by itself is 1

(3a - 5)/c = 1

multiply c:

3a - 5 = c

3a = c + 5

a = (c + 5)/3
