Answer:
She runs about 4.2 miles.
Step-by-step explanation:
6/50 = x/35
6*35 = 50*x
210 = 50x
50x = 210
x = 210/50
x = 4.2
She runs about 4.2 miles.
Since the whole segment is 18, we can add the 4x and 2x and set it equal to 18.
Combine like terms.
Divide both sides by 6 to isolate x:
Seven times eight equals fifty six
