Answer:

12.3 - 7.9x

Step-by-step explanation:

I added the numbers without variables first then I added the numbers with variables:

Answer:

x = 1.6

Step-by-step explanation:

Simplify the expression

8.9 – 1.4x + (–6.5x) + 3.4

8.9 - 1.4x + (-6.5x) + 3.4

collect like terms

8.9 + 3.4 - 1.4x - 6.5x

12.3 - 7.9 x = 0

take 7.9x to the left side

12.3 = 7.9x

divide both sides by 7.9

x = 12.3/7.9

x = 1.55696202532

x = 1.6

How to convert 3.248 repeating decimal with 48 repeating into a simplified fraction

Sonja [21]

Answer:

$x=\frac{536}{165}$

Step-by-step explanation:

Let X be the value of 3.2484848.... infinite times

Multiply by 100

$x=3.24848....\\100x = 324.8484.....$

Subtract to get

$100x-x = 324.8484...-3.248484....\\99x = 321.60\\x=\frac{321.6}{99} \\x=\frac{1072}{330} \\x=\frac{536}{165}$

Thus the number 3.248 repeating decimal with 48 repeating in fraction form is

$\frac{536}{165}$
