Answer:
7 days
Step-by-step explanation:
So! Ms. Masi earns $11.25 everyday, and is paying her brother back everyday. Let's make an equation to solve for the number of days!
11.25d = 72 <em>(d = # of days)</em>
<em>Now, we have to solve this equation to see how many days (d) it will take Ms. Masi to pay her brother back.</em>
<em></em>
11.25d = 72
÷11.25 ÷11.25 (Divide by "11.25" to get the variable by itself)
d = 6.4
<em>Since, she only gets 1 pay per day, Ms. Masi will have to wait til her 7th day to pay her brother back.</em>

Hope this Helps! :)

Answer: D , p = n (800 - 450) - 3000
Step-by-step explanation: Firstly, you have to account for how much money Rafael is making off of each computer (800 - 450). That factor is then multiplied by the variable "n" which represents the amount of computers sold. Lastly, since this is an equation to calculate his monthly profits, you have to subtract the rent that he is paying ($3000) from the total profit that he made off of selling the computers. Therefore, giving you the equation
P (profit) = n (amount of computers sold) (800-450) - 3000 (rent).
Answer:
C7,3=7!( 3!)( 7−3)!= 7! I think tell me if I'm wrong?
Step-by-step explanation:
- a . write the formula for finding area that is area= L by W so to get w will area over length so 4731/83= 57
- perimeter=2( L+ W ) so substitute so that it looks like this 318= 2(L + 72 ) then open the bracket 318= (2L + 144) then move 144 to the other side so 318 - 144 = 2L then you get 174= 2L divide both sides by 2 and your length is 87
Assign x to adult tickets and y to student tickets, then set up the system
5x+y=2465 and
x+y=1077
You can subtract the second equation from the first to get
4x=1388
=> x=347
Then to find y do 1077-347 to find
y=730
Final answer:
347 adult tickets and 730 student tickets were sold.
Hope I helped :)
