Mathematics
1 answer:
erma4kov [3.2K]3 years ago
8 0

Answer:

56

Step-by-step explanation:

Simplifying

x + 7x = 56 + 8

Combine like terms: x + 7x = 8x

8x = 56 + 8

Combine like terms: 56 + 8 = 64

8x = 64

Solving

8x = 64

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Divide each side by '8'.

x = 8

Simplifying

x = 8

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.
