uranmaximum [27]

Answer:

Step-by-step explanation:

$\bold{METHOD\ 1:}\\\\p\%=\dfrac{p}{100}\\\\30\%=\dfrac{30}{100}=0.3\\\\30\%\ of\ 8\ cups\to0.3\cdot8\ cups=2.4\ cups$

$\bold{METHOD\ 2:}\\\\\begin{array}{ccc}100\%&-&8\ cups\\\\30\%&-&x\end{array}\qquad\text{cross multilpy}\\\\100x=(30)(8)\\\\100x=240\qquad\text{divide both sides by 100}\\\\\dfrac{100x}{100}=\dfrac{240}{100}\\\\x=2.4$

The length of a rectangular poster is 9 more inches than two times its width. The area of the poster is 161 square inches. Solve

irinina [24]

Answer:

<u>Width = 7 inches</u>

<u>Length = 23 inches</u>

Step-by-step explanation:

Let :

length = 2x + 9
width = x

Equating to area :

(2x + 9)(x) = 161
2x² + 9x = 161
2x² + 9x - 161 = 0
2x² - 14x + 23x - 161 = 0
2x(x - 7) + 23(x - 7) = 0
x - 7 = 0
x = 7

Dimensions are :

<u>Width = 7 inches</u>
Length = 2(7) + 9
<u>Length = 23 inches</u>
