Ron asked 18 classmates wether they prefer granola bars over muffins. he used a calculator to compare the number of classmates who said yes to the total number he surveyed. the calculator showed the result as 0.66666667. part awrite this number as a fraction part bhow many students prefer granola bars over muffins? don't answer if you are not sure. : )

Part A =

Part B = 12

Step-by-step explanation:

Given : Total number of classmate surveyed = 18

Proportion of people said yes ,they prefer granola bars over muffins = 0.66666667

Since 6 is repeating after decimal , so we can write this value as

Let     (1)

Multiply 10 on both sides , we get

      (2)

Subtract (1) from (2), we get

Divide 9 on both sides , we get

Thus , the required fraction in Part A =

The number of students prefer granola bars over muffins will be :-

Hence, 12 students prefer granola bars over muffins.

Thus , the required answer for Part b = 12

x = -4

step-by-step explanation:

- 20 - 4(x + 3) = 4x

=> -20 - 4x - 12 = 4x

=> - 32 -4x = 4x

=> -32 = 4x + 4x

=> - 32 = 8x

=> -32/8 = x

=> -4 = x
