Answer 2
Answer: x-Charlie\ age\ny-Marty\ age\n\nChrlie\ is\ 24\ years\ older\ than\ Marty:x=y+24\nThe\ total\ years\ old\ of\ both\ are\ 130:x+y=130\n\nTherefore\ we\ have:\n \left\{\begin{array}{ccc}x=y+24&(1)\nx+y=130&(2)\end{array}\right\n\nsubtitute\ (1)\ to\ (2):\n\n(y+24)+y=130\ny+24+y=130\n2y+24=130\ \ \ \ |subtract\ 24\ from\ both\ sides\n2y=106\ \ \ |divide\ both\ sdies\ by\ 2\n\boxed{y=53}

Subtract\ the\ value\ of\ y=53\ to\ the\ (1):\n\nx=53+24=\boxed{77}\n\n\boxed{ \left\{\begin{array}{ccc}x=77\ny=53\end{array}\right}\n\nAnswer:\nCharlie\ age:77\nMarty\ age:53

40,43,40,39,50,23 what is the median?

Answers

Median is the middle number, but since there is 6 numbers.
Put them in order first
23,39,40,40,43,50
Well in middle is 40 for both sides
So to solve median for this you'd add the two middle numbers together since there is even set of numbers.
40+40 =80 then divide by 2
80÷2=40
Median = 40
*Follow This Example for any other even sets of numbers for Median*
The median of this data set is 40. This is because when put in order from greatest to least the order is:
23, 39, 40, 40, 43, 50
So the middle number is 40.

Simplify the expression 18 + 12xa 2 (9 + 5x )
b 3(6 +3x)
c 6 ( 3 + x)
d (3 + 2x)
​

Answers

Answer:

c:) 6(3 + 2x)

Step-by-step explanation:

The given expression is 18 + 12x. To simplify this expression, we can first look for any common factors that can be factored out. In this case, we can factor out 6, which gives:

18 + 12x = 6(3 + 2x)

So, the simplified expression 18 + 12x is 6(3 + 2x).

for #3 Nelson scored 29, because Craig scored 12 and Marla scored twice as craig, which was 24. After that we found out that she has 5 fewer than Nelson, witch would be plus 5.
i think the answers would be 
1.) 4 1/2 * 4 2/3= 9/2 * 14/3 then i canceled out 9 and 3 and 2 and 14 and got 3*7= 21 pounds
2.) 5 5/8 * 1 5/9= 45/8 * 14/9 then i canceled out 45 and 9 and got 5/8 * 14= 19/8
3.) 12*2-5 and if you want it solved its 12*2= 24 -5= 19
4.) 66/8 = 8.25 thats how much yvette earns and then you would just do 68.8/8=8.60 thats how much lizbeth earns 
5.) it would be 100 because 10*10 = 100 and 4*25=100 and no other smaller number could fit into it 
6.) 4 5/8 + 3 3/4 - 11 1/8
37/8 +15/4= 37/8+30/8=67/8
67/8-11 1/8= 67/8-89/8= 22/8 or 2 3/4
