Find the unit rate for miles by dividing the time by the miles.
50 / 2.5 = 20
So it takes 20 minutes for her to walk 1 mile.
X+5=18
first get rid of the 5
so X+5-5=18-5
which makes X=13

Answer:
Total number of painters = 25 painters
Step-by-step explanation:
Interior painting = 10 painters
These painters made up 40% of the painting crew
how many painters in all worked on this job?
Let
Total number of painters = x
Interior painters = 40% of x
10 = 40% * x
10 = 0.4 * x
10 = 0.4x
x = 10/0.4
x = 25 painters
Total number of painters = x = 25 painters
