How to convert a repeating decimal to a fraction when only 1 digit is repeating?

1 answer:

5 0

Example 0.777777

x = 0.77
10(x = 0.77) ----(10 because it is repeating by the tenth digit. if repeating by 2 digits like 0.2828, you'll multiply by 100)

10x = 7.77
-(x = 0.77)
9x = 7.00

Answer:

c) 3x - 45 = 10

Step-by-step explanation:

$\frac{1}{5}x-3=\frac{2}{3}\\\\\frac{1}{5}x-\frac{3*5}{1*5}=\frac{2}{3}\\\\\frac{x-15}{5}=\frac{2}{3}\\$

Cross multiply,

3*(x - 15) = 2*5

3*x - 3*15 = 10

Congruent distance is a term used for distance with equal measurements. EA and EB are congruent; FA and FB are also congruent

I've added as an attachment, the image of the complete question.

From the attached image of the circles, we have the following observations

Points A and B are at the centers of both circles
Point E is at the exact point of intersection of both circles
Point F is also at the exact point of intersection of both circles (opposite point E).

These observations mean that:
