Answer:
$6.25
Step-by-step explanation:
2000ml = 2 litres
2.5L - 2L = 500ml
So now we know that without the 500ml, it is 5 dollars.
Find out how much 500 ml cost.
2000ml = 5.00
1ml = 5.00 ÷ 2000 = 0.0025
500ml = 0.0025 x 500 = 1.25
2L + 500 ml = 2.5L (which 2.5L costs 6.25)

Answer:
a = 19
Step-by-step explanation:
Given the equation of:
First, multiply both sides by 3. That will clear the denominator which makes it easier to solve for a variable:
Subtract both sides by 5 to isolate the variable:
Therefore, the value of a is 19.
<u>The correct answer</u> is:
4.
Explanation:
In scientific notation, we place the decimal behind the first non-zero digit in the number. For 75,200, this is 7.
We then count the number of places we must move the decimal to place it here. In this problem, we move the decimal 4 places. This is the exponent for 10.
