subtract 4x from both sides
-2y=14-4x
divide each side by -2
y=2x+7
55/6.21 = x/1....55 mins to 6.21 miles = x min to 1 mile
cross multiply
6.21x = 55
x = 55/6.21
x = 8.86 minutes

Answer:
196, 245, 294
Step-by-step explanation:
sum the parts of the ratio, 4 + 6 + 6 = 15 parts
Divide the total by 15 to find the value of one part of the ratio
735 ÷ 15 = 49 ← value of 1 part of the ratio, thus
4 parts = 4 × 49 = 196
5 parts = 5 × 49 = 245
6 parts = 6 × 49 = 294
