This is what i would do i would do this is every student has 40 then 1 student has 40 then he gets a movie ticket so 40 - 5 = 35 then he buys candy for 7.50 so 35 - 7.50 = 27.5 then buys a 2 dollar trolley ride so 27.5 - 2 = 25.5 so every student was left with 25 dollars and 5 cents
Answer:
6n + 12
Step-by-step explanation:
Given an integer n, the 3 consecutive even integers greater than 2n are 2n+2, 2n+4 and 2n+6
Taking their sum;
Sum = (2n+2)+(2n+4)+(2n+6)
Sum = 2n+2n+2n+2+4+6
Sum = 6n + 12
Hence the sum of the 3 consecutive even integers greater than 2n is 6n+12
Answer:
7
Step-by-step explanation:
Answer:
The answer is 4.
Step-by-step explanation:
1. find the factors of 16(1,2,4,4,8,16) and of 28(1,2,4,7,14,28)
2. find the highest factor of the two Factored #.(4)
I'll do 3 and 4, and you can do 5 and 6 on your own!
For 3, we know that a perpendicular line's slope is -1/the other one, so the form is y=x/5+b (b being any number). Plugging -5 and -3 in, we get -3=-1+b. Adding 1 to both sides, we get -2=b and our equation being y=x/5-2 (since our standard form is y=mx+b with y and x remaining variables)
For 4, parallel means the same slope, so we have y=-2x/5+b. Plugging (2,4) in, we get 4=-4/5+b. Adding 4/5 to both sides, we get 4+4/5=b and our equation being y=-2x/5+4+4/5
