There are 225 women in the race.
Step-by-step explanation:
Total people in the race = 234
Let,
x represents the number of women in race.
y represents the number of men in race.

x=25y Eqn 2
Putting x=25y in Eqn 1
Dividing both sides by 26
Putting y=9 in Eqn 2
There are 225 women in the race.

Answer:In expression x-2 coefficient of x is equal to one.
Let a be "a" x's coefficient.
If we put "a" to Your equation, it should be looks like:
ax-2
We know that there is only one x, so expression ax have to be equal x
Now we get
From this equation we know that coefficient x "a" is equal to 1.
Answer:
Due to having 24 divisors.
Step-by-step explanation:
360 has many factors which might be the reason it was chosen for the number of degrees in a full turn. There are total 24 divisors of 360 number which make it the highest factors among all numbers. All circles are divided into 360 even parts so that the Sun would move through 1 part each day. Each of these parts was describes 1 degree and this division give us the idea that a circle contains 360 degrees so we can say that this is the reason that 360 is chosen in degrees.
