Faris's gas tank is 1/10 full. After he buys 24 liters of gas, it is 2/5 full. How many liters can Faris's tank hold?
Arisa [49]

Answer:

80 liters

Step-by-step explanation:

24 liters is the difference between 2/5 full and 1/5 full.

Let x = number of liters in full tank.

2/5 x - 1/10 x = 24

4/10 x - 1/10 x = 24

3/10 x = 24

1/10 x = 8

x = 80

Answer: 80 liters

How many terms are in the arithmetic sequence 1313, 1616, 1919, ……, 7070, 7373?
Nataliya [291]
To find the number of terms in the arithmetic sequence, we need to use the formula 
a_{n}= a_{1}+(n-1)d    
where a_{n} is the nth number, a_{1} is the first number, n is the number of terms and d is the difference of the two consecutive numbers.
7373 = 1313 + (n - 1)(303)
7373 = 1313 + 303n - 303
7373 = 1010 + 303n
7373 - 1010 = 303n
6363 = 303n
6363 ÷ 303 = n
n = 21

Therefore, there are 21 terms in the arithmetic sequence given.
