a = 11(4b + c) Multiply/distribute 11 into (4b + c) [multiply 11 to 4b and c]
a = 44b + 11c Subtract 44b on both sides
a - 44b = 11c Divide 11 on both sides to get "c" by itself
You can simplify it to this(but Idk if you have to):

Answer:
Step-by-step explanation:
v=d/t (average velocity equals distance divided by time)
26.2mi/5.8h=4.5mi/h
So Mackenzie runs approximately 4.5 miles in an hour (rounded to nearest tenth of a mile)
Step 1 ) Apply numbers into fraction form. Include variables to represent numerator and denominator.

Note: w = week; d = dollars
Step 2 ) Multiply both sides by 800 to change 1d into 800d.



This means that the amount of weeks it'll take to reach 800 dollars is...
<u><em>1,600 weeks.</em></u>
