I'm confused....so the numbers above are unnecceary?
Answer:
A burger cost five times as much as a fries.
Step-by-step explanation:
Let F represent fries
Let b represent burgers
From the question:
An order of fries and five burger can be written as:
f + 5b
Three orders of fries and two burgers can be written as:
3f + 2b
But an order of fries and five burgers cost twice as much as three orders of fries and two burgers. This can be written as:
f + 5b = 2(3f + 2b)
Now, we shall make b the subject of the above equation. This is illustrated below:
f + 5b = 2(3f + 2b)
Clear bracket
f + 5b = 6f + 4b
Collect like terms
5b – 4b = 6f – f
b = 5f
Thus, a burger cost five times as much as a fries.
196−−−√
25−−√
81−−√
Should be your perfect squares!
