Hello!

Angles CAD and EAB are congruent.

The reason why is that they are vertical angles. Their points meet and therefore they are congruent.

I hope this helps!

A truck can be rented from Company A for $80 a day plus $0.30 per mile. Company B charges $20 a day plus $0.50 per mile to r

mylen [45]

Write equations for both companies:

Company A = 80 + 0.30x

Company B = 20 + 0.50x

X = number of miles.

Set the equations to equal and solve for x:

80 + 0.30x = 20 + 0.50x

Subtract 0.30x from both sides:

80 = 20 + 0.20x

Subtract 20 from both sides:

60 = 0.20x

Divide both sides by 0.20:

x = 60 / 0.20

x = 300

The answer is 300 miles.

This is all it gave me 6 C 2 = a0

frozen [14]

Answer:

$\binom{6}{2} = a_{0}=15$

Step-by-step explanation:

$\binom{6}{2} = a_{0}$

$\binom{n}{r} =\frac{n!}{r!\times(n-r)!}$

It is representing a combination form where, n is number of items we have and r is the number of items we choose from n

Here, n = 6 , r = 2

$\binom{6}{2} =\frac{6!}{2!\times(6-2)!}$

= $=\frac{6!}{2!\times(4)!}$

$n!=n\times(n-1)\times(n-2)\times(n-3).....\times3\times2\times1$

$=\frac{6\times5\times4!}{2\times(4)!}$

$=\frac{6\times5}{2}$

$={3\times5}$

$={15}=a_0$

Thus, $\binom{6}{2} = a_{0}=15$
