Say x = 0.77--
Then 10x = 7.7--
Then 10x - x = 7 => 9x=7 => x=7/9

Say x = 2.3-
10x = 23.3-
10x-x = 9x = 21 => x = 21/9

last one is a bit tougher because it has alternating digits

Say x = 1.013--
100x = 101.313--
100x-x = 99x = 100.3 = x = 1003/990

I multiplied the final fraction with 10 to get integers.

A diameter is a chord. <br> True or false and why?
Lena [83]

Answer:

true.

A chord that passes through the center of a circle is called a diameter and is the longest chord.

Step-by-step explanation:

A diameter satisfies the definition of a chord, however, a chord is not necessarily a diameter. This is because every diameter passes through the center of a circle, but some chords do not pass through the center. Thus, it can be stated, every diameter is a chord, but not every chord is a diameter.

i hope this helps you.      :)

What are the letters
marin [14]
E = 7
F = 8
G = 1

First find a number that multiplies by 4 to make a number ending in 2. The options are either 3 or 8.
Try the full multiplication with both 3 and 8 and see which one works. 
Using 3 works up until you try and work out E as E would have to be a two digit number for it to work so therefore the answer to F must be 8. 

Hope this helped.
