Equation: 30 + -2x = 30 + x

400 people were surveyed about their eye color. 8% of the people surveyed have green eyes. how many people had green eyes​
VashaNatasha [74]

Answer:

32

Step-by-step explanation:

The problem above can be solved by using the <em>multiplication operation</em>.

Given: 400 people

           8% of the people with green eyes

Let's solve:

Let x be<em><u> the number of people with green eyes.</u></em>

x = 400 x 8%

x = 400 x (0.08)

x = 32

So, the number of people surveyed with green eyes is 32. The rest of the surveyed people (368) have a different eye color.

The length of a rectangle is 3ft less than double the width, and the area of the rectangle is 14ft^2 find the dimensions of rect
german

Answer: 4\times 3.5\ ft^2

Step-by-step explanation:

Given

area of the rectangle is A=14\ ft^2

Suppose width is given by w

So, length is l=2w-3

The area of a rectangle is A=l\times w

putting values

\Rightarrow A=(2w-3)w\\\Rightarrow 14=2w^2-3w\\\Rightarrow 2w^2-3w-14=0\\\Rightarrow 2w^2-7w+4w-14=0\\\Rightarrow w(2w-7)+2(2w-7)=0\\\Rightarrow (2w-7)(w+2)=0\\\\\Rightarrow w=\dfrac{7}{2}\ ft

length is l=4\ ft
