Step-by-step explanation:
If you that this would be 10:5 you would be half correct
Solution:
No. of boys in glee club:No.of girl in glee club
10:5
(divided by the table of on both sides)
2:1
This is how I'd solve it:
bench = x x+3x=600
table = 3x 4x=600
x=150
The bench costs <u>$150</u> and the table costs <u>$450</u>; combined, they cost $600, so it's correct. I hope this helps you!
Answer: 19 cm
<u>Step-by-step explanation:</u>
![A_{trapezoid}=\frac{b_{1}+b_{2}}{2}*h](https://tex.z-dn.net/?f=A_%7Btrapezoid%7D%3D%5Cfrac%7Bb_%7B1%7D%2Bb_%7B2%7D%7D%7B2%7D%2Ah)
99 = ![\frac{(x+4 + x+9}{2}*(x - 4)](https://tex.z-dn.net/?f=%5Cfrac%7B%28x%2B4%20%2B%20x%2B9%7D%7B2%7D%2A%28x%20-%204%29)
99 = ![\frac{(2x + 13}{2}*(x - 4)](https://tex.z-dn.net/?f=%5Cfrac%7B%282x%20%2B%2013%7D%7B2%7D%2A%28x%20-%204%29)
198 = (2x + 13)(x - 4)
198 = 2x² + 5x - 52
0 = 2x² + 5x - 250
0 = 2x²- 20x + 25x - 250
0 = 2x(x - 10) + 25( x - 10)
0 = (2x + 25)(x - 10)
0 = 2x + 25 or 0 = x - 10
= x or x = 10
Since length cannot be negative,
can be disregarded
Larger base: x + 9 = 10 + 9 = 19
