Answer:
2025
Step-by-step explanation:
Given a starting date of 2000 with an initial population of 1 million.
If it takes 25 years for the population to double, then the population will be 2 million in 2025.
Because 2000 + 25 = 2025.
4:6 x:18
Lets solve for x
Cross multiply
4*18 = 72
6*x = 6x
6x = 72
6x/6 = 72/6
x = 12
Answer: x = 12
Answer:
$80 was on the gift card to begin with
Step-by-step explanation:
Let the initial money be x
Peter spent (1/2)*x
Peter added 10
<em>Before adding more money on the gift card Peter had x -(1/2)x left on the gift card which is (1/2)x</em>
<em>After loading more money Peter had (1/2)x + 10</em>
(1/2)x = 40 <em>(money spent by Peter)</em>
x/2 = 40
x = 80
