Answer:
1312.5 minutes
Step-by-step explanation:
For her phone service, Lucy pays a monthly fee of $25, and she pays an additional $0.06 per minute of use. The least she has been charged in a month Is $103.72
What are the possible numbers of minutes she has used her phone in a month?
Use m for the number of minutes, and solve your inequality for m.
The term least = ≥ = greater than or equal to
Our inequality equation is given as:
$25 + $0.06 × m ≥ $103.72
25 + 0.06m ≥ 103.72
0.06m ≥ 103.72 - 25
0.06m≥ 78.75
m ≥ 78.75/0.06
m ≥ 1312.5 minutes
The possible number of minutes she used is 1312.5 minutes
The answer to this is 3x+12
We know that
the scale factor on the blueprint is-------> 12 cm/20 m------> 3 cm/5 m
if 3cm on a blueprint-------------> represent 5 m in the actual
X cm---------------------------------> 15 m
X=15*3/5------>X=9 cm
the answer is
9 cm
Answer:
24 cm

Answer:
Step-by-step explanation:
We start by selecting our pivot column as the most negative value on the bottom row.
This means our pivot column is 
. We now generate a new column by diving our pivot value by our value on the right-most column. This gives us (on a new row)
P/V
12/1 = 12
4/2 = 2
4/1 = 4
We pick our smallest positive value to be our pivot row.
This means our pivot row is our second row, and our pivot column is our first column. We now divide our entire row by our pivot point (our intersection of these two pivots)
This gives us our new second row as
1 3 0 1/2 0 0 2
now we need to eliminate our 
values from our other rows.
old row 1 - new row 2 gives us new row 1
row two stays the same
old row 3 - new row 2 gives us new now 3.
old row P + 2 new row 2 gives us new row P
After the first iteration of this algorithm this gives our tableau as: (see attached screenshot)
