There are 0 solutions because the lines are parallel and will never intersect.
Answer:
x + .20 = 1
Step-by-step explanation:
The equation would be x + .20= 1, or 1.00, because if you turn 20% into a decimal, it becomes .20. The total you are trying to find is 1 whole, in which this case it would simply be one as there is no other information. The x is first as if you had the .20 first, you would have to divide each side by .20, which would make x = 5, and that would not make sense.
Finding X: To find, subtract on each side by .20 due to the fact you are adding and need to do the opposite, .20-.20 cancels out and 1.00-.20 is .80, so you are left with x=.80
Let us set up an equation, to determine the list price. X represents the original price
.12 * x = 25
In order to solve for X, you must divide .12 from both sides
x = 25/.12
After you divide, you should get the number 208.33
25/.12 = 208.33
So, the original list price is $208.33
Answer:
.83333333 or 5/6
Step-by-step explanation:
Make common denominator
204/468 + 429/468 = 633/468 - (195/468 + 48/468)
Simplify: 633/468 - 243/468
390/468 can be further broken down to 5/6 if you divide by a common factor which is 78.
Answer:
$8.50
Step-by-step explanation:
I don't know what Alls are, but if Carlos insists, we can calculate how much he can spend on Alls with the expression:
($31.50) + r 
$40
This says the sum of what Carlos has already spent (hot dogs and hamburgers) plus the amount he spends on Alls (rolls?), r, must be equal to or less than the $40 he has allowed himself to spend.
($31.50) + r $40
r $40 - $31.50
r $8.50
