Answer:
Each apple costs $1.20 and each orange costs $1.
Step-by-step explanation:
Let x represent the number of apples and y represent the number of oranges.
For the fruit you bought, 5 apples and 4 oranges, we have 5x+4y. This costs $10. This gives us the equation
5x+4y = 10
For the fruit your friend bought, 5 apples and 5 oranges, we have 5x+5y. This costs $11. This gives us the equation
5x+5y = 11
Together we have the system
We will eliminate x by subtracting the bottom equation from the top:
Divide both sides by -1:
-1y/-1 = -1/-1
y = 1
Each orange costs $1.
Substitute this into the first equation:
5x+4(1) = 10
5x+4 = 10
Subtract 4 from each side:
5x+4-4 = 10-4
5x = 6
Divide both sides by 5:
5x/5 = 6/5
x = 1.2
Each apple costs $1.20.
It is 50% because it is half of the total
Answer:
- 22
Step-by-step explanation:
A fall of degree = 0.5 degrees is represented as
- 0. 5 degrees
The temperature at 2 : 00 is therefore
- 21.5 - 0.5 = - 22 degrees
V = 4/3 * pi * r^3
V = 4/3 * pi * 8.4^3
Simplify exponent:
V = 4/3 * pi * 592.704
Multiply:

Idk what an inequality is, but if you want i can tell the steps to find the number of days jim can rent the car:
250x$0. 10= $25(money needed to travel 250 miles)
$115-$25=$90(money remaining to jim to rent the car)
$90/$21=4(days jim can rent the car)
