Answer: White House tours are scheduled on a first come, first served basis and they must be requested a minimum of 21 days in advance of your visit. Requests can be submitted up to three months in advance. The earlier, the better as only a limited number of spaces are available.
Step-by-step explanation: u need to tour to get in
You can set up an system of equations
x=2y+8
x-y=25
Substitute x in to the second equation
2y+8-y=25
y+8=25
y=17
Substitute the y back in to the first equation.
x=2(17)+8=42
Answer:
i tried on a calculator and it gave me 211.125
I'm not really good at math but I would like to help.
If each call is $.08, then the card can call last for 250 minutes.
The call lasted 202 minutes. Divide 16.16 by .08.
The equation would be y = 25x + 50
In order to find this equation, we need to know how much the gift from her grandparents was. To do so, we have to find out how much she's saved from dog walking.
Since she saves $25 a month for 7 months, we can find the total amount as:
25*7 = 175
Then we can subtract that from the total she has saved to find the amount for the gift.
225 - 175 = 50
Finally, we put the amount per month in the equation with the gift as the y intercept to create the equation above.
