2:7=1:3.5
for every cm on the map, it is 3.5 times that in real life

so total legnths
17 times 3.5+18 times 3.5+18 times 3.5+19 times 3.5=
59.5+63+63+66.5=
252

5a -5=7+2+2a I really need help

Answers

5a-2a=7+2+5
a(5-2)=14
a=14/5-2
a=14/4
a=3.5

Answer:4 2/3

Step-by-step explanation:

5a-5=7+2+2a (combine like terms; 7+2=9)

5a-5=9+2a (subract 2a from both sides; 5a-2a=3a)

3a-5=9 (add 5 to both sides; 9+5=14, -5+5=0)

3a=14 (divide both sides by 3; 14/3= 4 2/3)
