Answer:
No, (-1,4) is not a solution.
Step-by-step explanation:
This is actually a simple problem...don't overcomplicate it!
All you need to do is plug the values into the equation and solve!
y < 2x + 5
4 < 2(-1) + 5
4 < 3
Equation: 120 ≥ 10n + 20
Subtract 20 from both sides,
100 ≥ 10n
Divide both sides by 10,
10 ≥ n
It means, it is equal or Smaller than 10.
So, the answers would be: 7, 8, 9, 10
Hope this helps!
Answer:
20 people
Step-by-step explanation:
well we know that only going to the restaurant every person must pay $7
so we have only $3 extra
those 3 dollars times the number of people must give 60 dollars

so 20 people must go, to pay only $10
Perimeter is all the way around and area is l x w
So 5 x 2 would be 10.....and 5 + 5 + 2 + 2 = 14
So the dimenstions are 5 x 2
Answer:
1. 6x+10
2. 3x+
/5
3. 2.5x-1.1
I'm not sure if I did it in the correct format. :(
