'v' visits.... would get her 12.5v points
She needs at least 155 points... Meaning the least she needs is 155. Also meaning she needs 155 or More...
We would represent that with a "Greater than or Equal to Sign ≥"
12.5v + 70 ≥ 155
12.5v≥155-70
v= 85/12.5
v=6.8.
Our answer can't be in decimal. She can't make 6.8 visits... Rather
The answer would be 7 Visits.
She needs a Minimum of 7visits.

Answer:
-2n - 12
Step-by-step explanation:
Combine like terms. Note that each term has one variable (n). Also note that one negative sign and one positive sign results in a negative sign.
-6n + (-12) + 4n = -6n + 4n - 12 = -2n - 12
-2n - 12 is your answer

Answer:
x = 6, y= -6
Step-by-step explanation:
-4x - 2y=-12
4x + 8y = -24
Add the two equations together to eliminate x
-4x - 2y=-12
4x + 8y = -24
------------------------
6y = -36
Divide each side by 6
6y/6 = -36/6
y = -6
Now we can find x
4x+8y = -24
4x +8(-6) = -24
4x -48= -24
Add 48 to each side
4x -48+48 = -24+48
4x = 24
Divide each side by 4
4x/4 = 24/4
x =6
