Answer:
The ratio between won and lost is 
Step-by-step explanation:
<u><em>The question in English is</em></u>
A table tennis team won 21 games and lost 12 games, what is the ratio between won and lost?
Let
x ------> the number of games won
y -----> the number of games lost
we have


we know that
To find the ratio divide the number of games won by the number of games lost
so

substitute the values

Simplify

Answer:
the equation of the line is y = -3x - 6
Step-by-step explanation:
Note that since (0, -6) is the y-intercept, we can write the slope-intercept equation of the line as y = mx - 6. The other given point is (-2, 0) (which happens to be the x-intercept also). Starting with y = mx - 6, replace y with 0 and x with -2:
0 = m(-2) - 6. We now solve this for the slope, m: 0 = -2m - 6 becomes
2m = -6, or m = -3.
With m = -3 and b = -6, the equation of the line is y = -3x - 6
Given :
There are 23 red shirts and 16 white shirts they will be put onto shelves in piles of 8.
To Find :
How many shirts will not fit evenly into 8 piles.
Solution :
We need to find the number of shirts which will not fit evenly into 8 piles.
What we need is the remainder of 23 divided by 8.
23 = 8×2 + 7
So, their are 7 shirts which will not fit evenly.
Hence, this is the required solution.
