I do not have a video but to convert a fraction to a decimal, you divide the numerator by the denominator or make the denominator equal to one hundred. For example, to convert 1/5 to a decimal, you write 1/5 as 20/100, which as a decimal is written as .2
The equation has no solution because:
5(n+10)=5n+10n
5n+10n=5n+10n
I subtract 5n from both sides
10n=10n
Only one side is supposed to have the variable which is n, so the equation has no solution.
Answer:
The number of hamburgers sold was 126.
Step-by-step explanation:
Let h = number of hamburgers sold
let c = cheeseburgers sold
c+h = 378
c = 2h
Substitute c =2h into c+h =278
c+h =378
2h+h = 378
Combine like terms
3h = 378
Divide by 3
3h/3 =378/3
h =126
The number of hamburgers sold was 126.
