H^3+3h^2x+3hx^2+x^3 should be the answer
Answer:
$26.02
Step-by-step explanation:
Let the price of a skirt be A and that of coat be B
Iilly bought 6 skirts and 5 coats for a total of $452.62
That’s
6A + 5B = 452.62
Also, Lilly’s sister bought 3 skirts and 5 coats for $289.36
That’s
3A + 5B = 289.36
We now have two equations
1 . 6A + 5B = 452.62
2. 3A + 5B = 289.36
Subtract equation two from equation one
We have
3A = 163.26
Divide both sides by 3
3A/3 = 163.26/3
A = 54.42
A = $54.42
Now substitute 54.42 for A in either equations to get B the price of a coat
Using equation one, we have
6A + 5B = 452.62
6 x 54.42 + 5B = 456.62
326.52 + 5B = 456.62
Subtract 326.52 from both sides
326.52 - 326.52 + 5B = 456.62 - 326.52
5B = 130.1
Divide both sides by 5
5B/5 = 130.1/5
B = 26.02
= $26.02
A coat cost $26.02
Answer:
Greatest: Denmark
Least: U.S.
Step-by-step explanation:
The population density is calculated by dividing the population by the area.
U.S.
Population density = 272,648,000/9,364,520 = 29.1
Denmark
Population density = 5,248,000/42,077 = 124.7
Ghana
Population density = 18,339,000/237,533 = 77.2
Greatest: Denmark
Least: U.S.
4220.3 miles is the answer you are looking for
(a) q=0
You would simplify the equation.
3+9=12
12+q=12
Then you would eliminate 12 from both sides, by subtracting.
q=0
