Answer:
Yes, they're.
Step-by-step explanation:
30 = 1 * 2 * 3 * 5
Let, the age of Daniel = x
Then, Age of Kevin = x + 3
Two years ago, (x + 1) = 4(x - 2)
x + 1 = 4x - 8
4x - x = 1 + 8
3x = 9
x = 9/3
x = 3
In short, Your Answer would be 3 Years
Hope this helps!
Answer: 39, 46, 95
Step-by-step explanation:
Because 39 plus 46 is 85. Then we do 180 -85= 95
Answer:
firstly it is a four number combo with no repeating numbers so it has to include 5 but if you mean it like you said it 0
Step-by-step explanation:
sry i read it wrong the first time
IF -2/5 + -1/4 IS IN PARENTHESES:
skip this part if its not
(1/2) / (-2/5 - 1/4)
(-2/5 - 1/4) is equivalent to (-8/20 - 5/20) = -13/20
substitute -13/20 for (-2/5 - 1/4)
1/2 / -13/20
remember that division is the inverse of multiplication, so if we flip the second fraction, we can change the division sign to multiplication (when doing this, never flip the first fraction, you will not get the right answer)
1/2 * -20/13
simplify -20/2 to get -10
1 * -10/13 = <u>-10/13</u>
IF -2/5 + -1/4 IS NOT IN PARENTHESES:
1/2 / -2/5 +-1/4
PEMDAS : multiplication/division comes before addition / subtraction
1/2 / -2/5 = (apply the flip rule : read the chunk of text above if you don't know what it is) 1/2 * -5/2 = -5/4
subtract 1/4 form -5/4 now
-5/4 - 1/4 = -6/4
simplify
= <u>-3/2</u>
