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.

Sphinxa [80]

Answer:

25,26,27, and 28

Step-by-step explanation:

Write consecutive integers as x,x+1,x+2,x+3,x+4, and so forth.

x+x+1+x+2+x+3

3) Subtract 6 from both sides:

4x=100

4) Divide both sides by 4:

x=25

5) Plug in 25 for x for all 4 integers:

25
