Answer:
Maximum distance covered by John = 22.8 miles
Step-by-step explanation:
The cab company charges a flat fee of $2.25 plus $0.55 per mile.
Amount of money John has = $y
Let the number of miles traveled in $y = x miles
If John finds a cab charging same fee and $0.45 per mile,
y ≤ 2.25 + 0.45x
y - 2.25 ≤ 0.45x

Therefore, inequality representing the maximum distance covered by John,

If, y = $12.52

x ≤ 22.8 miles
Therefore, John will be able to travel the maximum distance = 22.8 miles.
The answer is 7234.56 inches cubed. The equation to find the volume of a sphere is 4/3*pi*r^3.
The equation would be 4/3 * 3.14 * 12^3.
4/3 * 3.14 * 1728
4/3 * 5425.92
7234.56
Answer:
x=10 and x-7 is the answer
Step-by-step explanation:
a)2x-7=13
2x=13+7
2x=20
x=20/2
x=10
b)3x+4=25
3x=25-4
3x=21
x=21/3
x=7
