Answer:
3n + 75
Step-by-step explanation:
Multiply n by 3 = 3n
Multiply 25 by 3 = 75
You don't say what the tax rate is. Supposing it were 5%, then your bill would be 1.05($29.99) = $32.49.
The answer is A. You would want to multiply the top by 4 to make y into 4y so that 4y and -4y and cancel when adding the two equations leaving you to solve for x.
Hope this helps.
Answer:
5 weeks
Step-by-step explanation:
We are given the following information;
- Price of gas in Bakersville as $2.10 per gallon
(increment per week is $0.20)
- Price of gas in Springfield as $2.60 per gallon
(Increment per week as $0.10 )
We are required to determine the number of weeks it will take for the prices to be the same in the two cities.
Assuming it will take n weeks for the prices to be the same, then
New price in Bakersville = $2.10 + $0.20n
New price in Spring field = $2.60 + $0.10n
Thus;
$2.10 + $0.20n = $2.60 + $0.10n
combining the like terms
0.10 n = 0.50
n = 5
= 5 weeks
Therefore, it will take 5 weeks for the prices to be the same both cities
Answer:
(0.3/1)x-1.7
Step-by-step explanation:
I used the format mx+b
m= slope
x= x value (usually stays as x when you write an equation and replace it with the x value when solving)
b= y-intercept (in this case when p is zero what is the q value)
y-intercept = -1.7 (in this equation found from the table)
slope= 0.3/1 (the rate it the numbers increase at. q is changing +0.3 each time and p is changing by 1. p (or the x value) goes on top of q (or the y value)) (I found the missing information in between 2 and 5)
hence you have (0.3/1)x-1.7
