Answer:
I'm assuming we need to find the number of minute she as used. to do that we can right an inequality with m being the number of minutes
18+0.06m≥88.56
we then just solve this like we would with any other algebra equation, First we subtract 18 from both sides.
0.06m≥70.56
Then we dives by 0.06
m≥1176
Rania has used at least 1176 minutes
Set f(b) = b^2 - 75 = to 0 and solve for b:
b^2 = 75
b^2 = 25(3)
b = plus or minus sqrt(25[3]) = plus or minus sqrt(25)*sqrt(3) = plus or minus 5 sqrt(3).

Answer:
X =30/7
Step-by-step explanation:
The first way would be something like:
-7x + 10 = -20. The first thing we would do is to subtract 10 from both sides.
Therefore,
-7x+10-10=-20-10
Simplified, we get
-7x=-30
Remove the negative symbols
7x =30
x=30/7
Second example:
10=7x - 20
Add 20 to both sides.
10+20=7x-20+20
Simplified,
30=7x
x = 30/7
