Use the Distance Formula to find the distance to the nearest tenth between A(-7, -4) and B(-2, 0).

goldenfox [79]

A(-7,-4) B(-2,0)
√[(x'-x)^2+(y'-y)^2]
√(-2-(-7)^2+(0-(-4)^2
√(5^2)+(4^2)
√25+16
√41

the distance is approximately 6.4 units

Answer:

Equation for 'x' is $\frac{1}{3}x=25$ .

There are <u>75</u> students in the football team.

Step-by-step explanation:

Let the number of students on the team be 'x'.

Given:

Number of players to have hair cut = 25

Number of players to have hair cut is one-third of the total students in the football team.

So, framing in equation form, we get:

$\frac{1}{3}x=25$

In order to solve this equation for 'x', we have to isolate 'x' on the left hand side.

So, we multiply both sides by 3. This gives,

$3\times \frac{x}{3}=25\times 3\\\\x=75$

Therefore, there are 75 students in the football team.
