Answer:
Step-by-step explanation:
We can simplify this equation down until we have x isolated.
If we add 17 to both sides:
Now we can divide both sides by 3:
So .
Hope this helped!
Answer:
4 and 5
Step-by-step explanation:
Let the numbers be x and y
If their sum is 9, hence;
x + y = 9 ....1
When reversed
10y+x = 2(10x+y)
10y+x = 20x + 2y
10y - 2y = 20x - x
8y = 19x
y = 10x/8 ...2
Substitute equation 2 into 1;
From 1;
x+y = 9
x +(10x/8) = 9
18x/8 = 9
18x = 72
x = 72/18
x = 4
Since x+y =9
y = 9-x
y =9-4
y = 5
Hence the numbers are 4 and 5

Answer:
Explanation:
There is a theorem in geometry that says:
In a circle, if two chords are equal in measure, then their corresponding minor arcs are equal in measure.
Those small tick marks on each of the chords means that they are equal in measure. So, following the theorem, the arcs are also equal in measure.
If they are equal and
arc AB = arc CB
arc AB = 24 feet
Then
arc CB = 24 feet
by substitution.
