<span>99(100x)+31=89
=> 9900x + 31 =89
=> 9900x = 89 - 31=58
=> x = 58/9900
Hope it helps !!!</span>
Answer:
horizontal line is this _________
pretend its lying down
vertical line is standing up
# of students who wore red = 150
# of students who did not wear red = 250
Total #. of students = 150 + 250
= 400
Percentage of students who wore red =
(# of students who wore red/Total #) * 100 = (150/400) * 100 = 37.5
∴ No of students who wore red = 37.5%
Answer:
Sí, 2 • 10 = 20. Luego factoriza 10, que también es divisible entre 2 (2 • 5 = 10). Ambos factores son primos, por lo que puedes detenerte. La factorización prima de 20 es 2 • 2 • 5, la cual puedes escribir usando la notación exponencial como 22 • 5.

Step-by-step explanation:
<u><em>The picture of the question in the attached figure N 1</em></u>
we know that
The area of the walkway around the rectangular pool, is equal to the area of two trapezoids (#1 and #2), plus the area of two smaller rectangles (#3 and #4)
see the attached figure N 2 to better understand the problem
step 1
Find the area of the two trapezoids (#1 and #2)
![A=2[\frac{1}{2}(b_1+b_2)h]](https://tex.z-dn.net/?f=A%3D2%5B%5Cfrac%7B1%7D%7B2%7D%28b_1%2Bb_2%29h%5D)
simplify

we have

substitute

step 2
Find the area of the two smaller rectangles (#3 and #4)
![A=2[LW]](https://tex.z-dn.net/?f=A%3D2%5BLW%5D)
we have

substitute
![A=2[(4)(6)]=48\ yd^2](https://tex.z-dn.net/?f=A%3D2%5B%284%29%286%29%5D%3D48%5C%20yd%5E2)
step 3
Find the area of the walkway around the rectangular pool
