-4 +11 is saying that assuming if a person owe 4 dollars and his friend gives him 11 dollars that he will pay back the four dollars and still have 7 dollars left
Answer:
see the explanation
Step-by-step explanation:
In this problem
I will assume that the total amount required for the trip is $1,200
so
Let
x ----> the number of weeks
we know that
The number of weeks multiplied by $75 plus $300 must be at least $1,200
In this context, the term "at least" means "greater than or equal to"
so
The linear inequality that represent this problem is

Solve for x
subtract 300 both sides


Divide by 75 both sides

therefore
The minimum number of weeks you need to save is 12
Answer:
13
Step-by-step explanation:
it's a 5,12,13 triangle
and we can find the sides by Pythagorean theorem:
a^2 + b^2 = root of c
25 + 144 = 169
root of 169 = 13
