Martha rented a sedan at a cost of $21.25 a day for three days. She drove 980 miles at 25 cents a mile. Gas cost $63.45 what was the cost per mile
Answer:
38 cents per mile
Step-by-step explanation:
Let us first calculate the total expenditure by Martha
= 21.25*3= $ 63.75
Cost of gas =$ 63.45
Therefore cost per mile = 127.2/980= 0.1297+0.25= $0.3797 or 38 cents per mile
Can you help me thank you
Answer:

Answer:
a = -b + 10x + 9/ x
Step-by-step explanation:
5(2x+3)−6=ax+b
ax+b=10x+9
ax +b+−b=10x+9+−b
ax=−b+10x+9
ax/x = -b+10x + 9 /x

solve for m
–m + 8 = –4m − 10
Answer:
m=-6
Step-by-step explanation:
-m + 8 = -4m -10
+m. +m.
8= -3m -10
+10. +10
18 = -3m
/-3m /-3m
-6=m
Answer:
m=-6
Step-by-step explanation:
–m + 8 = –4m − 10
Subtract 8 from both sides
-m+8-8=-4m-10-8
Simplify:
-m=-4m-18
Add 4m to both sides
-m+4m=-4m-18+4m
Simplify:
3m=-18
Divide both sides by 3
3m/3=-18/3
-18/3=-6
m=-6

(5x – 10x2) /(14x - 7)
Answer:
- [tex]\frac{5x}{7}[/tex]
Step-by-step explanation:
Given
[tex]\frac{5x-10x^2}{14x-7}[/tex] ← factor out 5x in the numerator and 7 in the denominator
= [tex]\frac{5x(1-2x)}{7(2x-1)}[/tex] ← factor out - 1 on the numerator
= [tex]\frac{-5x(2x-1)}{7(2x-1)}[/tex] ← cancel the common factor (2x - 1)
= - [tex]\frac{5x}{7}[/tex]

this isn't classified as a polynomial because polynomials do not contain variables raised to a negative number, such as this, which is raised to -3.
When looking at a graphed System of Equations,
how do you determine which line is the better
deal?
Answer:
Step-by-step explanation:
So, if we are looking to save money, then it would probably be a good choice to go for the least steepest line. Assuming Money stands for the Y axis and Quantity stands for the X axis, then looking at the least steepest line means the lowest Y axis, which translates to the least amount of money.
Which system of equations has one solution?
The volleyball team needs new uniforms. The students plan to sell plush toy eagles (the school mascot) for $5 each. The students find three companies on-line that sell stuffed mascots. Company A sells 12 eagles for $34.56. Company B sells 15 eagles for $42.90. Company C charges $51.30 for 18 eagles. Which company has the best buy?
Answer:
Step-by-step explanation:
A=34.56/12=$2.88 each
B=42.90/15=$2.86 each
C=51.30/18=$2.85 each
So C is the cheapest.
Provide an appropriate response.

solve the equation -9v-9=-27 for v.
Answer:
v=2
Step-by-step explanation:
-9v-9=-27
add nine to both sides
-9v-9+9=-27+9
simplify
-9v=-18
divide both sides by -9
-9v/-9 -18/-9
simplify y=2
hope this helps :) have a nice day !!
Answer:
v=2
Step-by-step explanation:
-9v-9=-27
add nine to both sides
-9v-9+9=-27+9
simplify
-9v=-18
divide both sides by -9
-9v/-9 -18/-9
simplify y=2
