Answer:
41 and 77
Step-by-step explanation:
x: his age the first time he went to space
y: his age the second time he went to space
the second time he went to space he was 5 years younger than twice the age when he went his first time, then:
y = 2x - 5
the sum of both ages is 118, then:
x + y = 118
If you replace y = 2x - 5 in x + y =118:
x + 2x - 5 = 118
3x = 123
x = 41
replacing x:
41 + y = 118
y = 118 - 41
y = 77
so when he was 77, he was 5 years younger than twice 41 ( 41*2 = 82 => 82 - 5 =77)
Answer:
-3/12
Step-by-step explanation:
In negative numbers, it's basically the opposite of regular numbers.
Let's explain negative numbers as debts. Let's say you owe a friend 1 dollar, and another 2 dollars. In a sense, you'll have -1 dollars, and -2 dollars. Which one is the greater number? It'll be -1 as you're only losing 1 dollar. Same goes here. Although 1 is a greater number than 3/12, in negative form it isn't.
