The full tank has a volume of x litres.
The tank is 1/6 full, so it has (1/6)x litres of gasoline.
Now you add 8 litres. The tank now has (1/6)x + 8 litres.
It is now 1/4 full. 1/4 full means it has (1/4)x litres.
Therefore, (1/6)x + 8 must equal (1/4)x.
(1/6)x + 8 = (1/4)x
Multiply both sides by the LCD which is 12.
12(1/6)x + 12(8) = 12(1/4)x
2x + 96 = 3x
Subtract 2x from both sides.
96 = x
x = 96
Answer: The tank holds 96 litres.
Answer:
x = 12
Step-by-step explanation:
Solve for x by simplifying both sides of the equation, then isolating the variable.
Answer:
Step-by-step explanation:
This is a simple Interest problem, where I = prt.
I is the interest earned;
r is the interest rate in decimal form;
p is the initial deposit; and
t is the time in years.
I = 5720(.06)(4) so
I = $1372.80
Answer:
m= 8n-7/10
Step-by-step explanation:
n- 5/2 + 5/4 m= -27/8 + 2n
n- 5/2 + 5/4 m-n = -27/8 +2n-4
-5/2 +5 /4m=- 27/8 +n
- 5/2 + 5/4 m + 5/2 = - 27/8+n+ 5/2
5/4 m =n- 7/8
4. 5/4 m=4n -4 . 7/8
5m=4n- 7/2
5m/5 = 4n/5 - 7/2 /5
m= 8n-7/10
Obviously it's a monstrosity.
