Given:
Sum of arithmetic sequence is 21.
Product of arithmetic sequence is 315.
I did a manual computation. Arithmetic sequence means that there is a constant difference between the two consecutive numbers.
x + (x+2) + (x + 2 + 2) = 21
3x + 6 = 21
3x = 21 - 6
3x = 15
x = 15/3
x = 5 1st number
x + 2 = 5 + 2 = 7 2nd number
x + 2 + 2 = 5 + 2 + 2 = 9 3rd number.
5 + 7 + 9 = 21
5 x 7 x 9 = 315
She sold 135 peaches, because if you multiply 2.50 eith 135, you'd get 337.5, the 0 can be added or not.
Answer:
-25.17 miles per gallon.
-It costs $49.02 to fill your tank.
Step-by-step explanation:
-To find the miles per gallon, you can use a rule of three:
17.2 gallons → 433 miles
1 gallon → x
x=(1*433)/17.2= 25.17
If your gas tank holds 17.2 gallons, you car can drive 25.17 miles per gallon.
-To find the cost to fill your tank, you have to multiply the price per gallon for the amount of gallons that the tank can hold:
$2.85*17.2=$49.02
It costs $49.02 to fill your tank.
