Answer:
11-12=-1
Step-by-step explanation:
There is numbers below zero
since 11 is 1 below 12
The answer is a negative number
and is -1
Let h represent hamburgers and c represent cheeseburgers. We can set up an equation:
h + c = 437
h + (h - 63) = 437
h + (h - 63 + 63) = 437 + 63
h + h = 500
2h = 500
2h / 2 = h
500 / 2 = 250
h = 250
250 hamburgers were sold.
To find how many cheeseburgers were sold, we subtract 250 - 63:
250 - 63 = 187
187 cheeseburgers were sold.
187 + 250 = 437
250 hamburgers and 187 cheeseburgers were sold on Thursday.
Answer:
Step-by-step explanation:
the answer is basically 4.5% and the 6%
It's pretty simple! So it looks like you are learning proportions. You would cross multiply to achieve your answer.
First, let's do your first problem:
2 12
--- = ----
5 n
You would take 5 and multiply it by 12 and get 60! Then you would do the same with 2 times n, giving you 2n (because you do not know what n represents YET.)
Now you should have this:
60=2n OR 2n=60
We must isolate our variable, in order to do that, get rid of two! But how? You would do this by dividing 2n by 2. Yet in equations, when you do something to one side, you must do it to the other because they must be EQUAL! (hence the "equa-" in equation)
2n=60
--- ---
2 2 DIVIDE 2 into 60
----------
n= 30 Simplify!
Your final answer for the first question is n= 30!
