Answer: See explanation
Step-by-step explanation:
Michael is X years old.
Jenny is twice as old as Michael. Thus means that Jenny = 2 × x = 2x
The sum of their ages is 57.
Therefore, x + 2x = 57
3x = 57
x = 57/3 = 19
Michael is 19 years
Jenny's age = 2x = 2 × 19 = 38 years
Answer:
Look Down
Step-by-step explanation:
85+2.5v=115
2.5v=30
v=12
Do you know how to graph the equation 2x-1?
If you do then graph it.
After, check the inequality - it is Y is less than the equation so you will be filling in everything below the line you graphed
IF you don't know how to graph:
You will have a line that goes up 2 then right 1
The equation is really 2/1 x as in 2 right 1 right
The line will start from y=-1 or 1 right below 0,0 because of the -1 at the end of the equation and the line will travel in both direction for infinity (Or as big as the graph is)
So start at y=-1 then go up 2, right 1 and place a point. Keep doing that (down 2 left 1 when going in the opposite direction) Finally just make a line through all those points you made
Answer: Number of distinct letter arrangements can be made from the letters of the word ‘ABBA’: =6
Number of arrangements start with A= 3
Number of arrangements finish with A =3
Step-by-step explanation:
Given word : ABBA
Total letters = 4
Number of A's = 2
Number of B's = 2
Number of ways to arrange n letters such that 
are line , 
are like , 
are like and so on :
So , the number of distinct letter arrangements can be made from the letters of the word ‘ABBA’:
When the word starts with A , then we need to arrange remaining three letters(BBA) :
Then , Number of arrangements start with A = 
∴ Number of arrangements start with A =3
Similarly ,
Number of arrangements finish with A =
∴ Number of arrangements finish with A =3
