On a team 5 girls and 2 boys scored a total of 41 points. The difference between the number of points scored by the 5 girls and
kolbaska11 [484]

Step-by-step explanation:

Let x be the number of points the 5 girls scored.

=> 41 - x is the number of points the 2 boys scored.

We have x + 29 = 41 - x or x - 29 = 41 - x.

=> 2x = 12 or 2x = 70

=> x = 6 or x = 35

We reject x = 6 as 6 is not a multiple of 5. (Each girl would have scored 1.2 points which is absurb)

So x = 35, each girl scored 35/5 = 7 points.

=> 41 - (35) = 6, each boy scored 6/2 = 3 points.

How do you multiply anything not specific? sorry
Contact [7]
If it says 3×8 its like saying 8+8+8=21.
It's just a faster way of adding.

Anything multiplied by 0 is 0.

Anything multiplied by 10 just add a 0 to the end of the number example 10×2=20.

Convert the recursive equation that is below into an explicit equation where a is the initial value and the time elapsed is 1 ye
aleksley [76]

Answer:

  f(n) = a+200(n -1)

Step-by-step explanation:

The constant difference between terms indicates the sequence is an arithmetic one. The explicit formula for an arithmetic sequence is ...

 an = a1 + d(n -1)

where a1 is the first term and d is the common difference.

Your first term is "a", and your common difference is 200, so the n-th term of the sequence is ...

  an = a + 200(n -1)

Written as a function of n, this is ...

  f(n) = a + 200(n -1)

_____

Based on the problem description, we cannot tell how n relates to time, so we have created an f(n) that gives the same result as the recursive definition of f(n).

What percent of 24 is 6
VMariaS [17]

To find what percent a part is of the whole, divide the part by the whole and multiply by 100.

percent = part/whole * 100%

percent = 6/24 * 100%

percent = 0.25 * 100%

percent = 25%

Answer: 25%
