Step-by-step explanation:
x = the number of goals of the top scorer.
y = the number of goals of the second top scorer.
z = the number of goals of the third top scorer.
x + y + z = 98
x = y + 8
y = z + 15
using the third in the second equation we get
x = z + 15 + 8 = z + 23
and now using this and the third equation in the first equation gives us
z + 23 + z + 15 + z = 98
3z + 38 = 98
3z = 60
z = 20
y = z + 15 = 20 + 15 = 35
x = y + 8 = 35 + 8 = 43
the player with the most goals scored 43 goals.
To write the function correctly, it is important to assign variables correctly and understand the situation of the problem clearly. For this, we let y the number of people and x as the number of songs played.
At x = 0 y = 567
at x = 1 y = 567 - 567(1/3)
at x = 2 y = 567 - 567(1/3)(1/3)
at x = 3 y = 567 - 567(1/3)(1/3)(1/3)
Therefore, the number of people left after x songs would be represented by the equation:
y = 567 - 567(1/3)x
y = 567 ( 1- x/3 )
Answer:
40 girls
Step-by-step explanation:
First you set up a proportion. 4 over 5 is equal to 32 over x
Use the baseball bat method (look up baseball bat method proportions and go to images if you dont know this is just how i learned it)
bb bat method gives you
32x5= 160
160/4= 40
Answer:
About 121 words per minute or WPM.
Step-by-step explanation:
A reader can read 850 WPM. If an average reader can read 1/7 of that, you divide 850 by 7 to get your answer.
850/7 = 121.42....
Then you can round to the nearest tenth to 121.
Complementary angles --- they add up to 90 degrees
