Answer:
The scale factor is 
Step-by-step explanation:
we know that
The scale factor is equal to the ratio between the side length of the scale drawing to the corresponding side length in the actual
so

<span> 3x+5y = 15
5y = -3x + 15
y = -3/5(x) + 3
hope it helps

Answer:
c
Step-by-step explanation:
given: miles traveled and cost
to find: which one is correct
solution:
miles traveled =25
And cost =80
80/25 = 3.2
similarity all $3.20 cost increase
so confusing i really need help with this math
