Answer: 5/2
Step-by-step explanation:
Cross multiply
18 = 8x - 2
20 = 8x
20/8 reduces to 5/2
So, let's see, Amber made 3 penalty shots off 4, now, 3 out of 4 is 75% or 3/4. So she's 75% of the time effective.
Lindsay has made 4 out of 6 penalty shots, 4/6 or 2/3, that's about 66% effectiveness.
Li has made 2 out of 3 penalty shots, that's 2/3, that's about the same 66% effectiveness.
so, which fraction is highest 3/4, or 2/3 or 2/3? neverminding the percentages, let's multiply all by the LCD, let's see from 4, and 3, and 3, the LCD is 12.
so, let's multiply all of them by 12, to get rid of the denominator, to see which is highest.

notice, Amber has the higher effectiveness rate, to make it through in the penalty kick.
Answer:
Step-by-step explanation:
The two sides add up to 12. If the third "side" of the triangle is 12, then 5 and 7 will lie horizontally on 12.
So the maximum value must be less than 12. What's the smallest x could be?
well 5 + something must be > than 7. If they are not larger than 7, then 5 and something will lie on 7 just as it did before. So how big is something?
5 + y > 7
5 - 5 + y > 7 - 5
y > 2
So the range is 2 < x < 12
How else could you write this?
2 < x
x < 12 is one way.
According to the figure, x+z must be 180°, so the answer is <span>x=86, y=75, z=95 , because 86 +95 = 181, it is near 180°
