Answer:

Step-by-step explanation:

Let x be the number of buses and y be the number of vans.

We know that there are 5 more buses than vans, therefore, we can set up:

$x=y+5$

Since a bus transports 55 people and a van transports 12 people, therefore, we can set up:

$55x+12y = 409\\$

Now lets solve the above two equations together by substitution

$55(y+5)+12y = 409\\\\55y+275+12y=409\\\\67y+275=409\\\\67y=409-275\\\\67y=134\\\\y=2,x=2+5=7$

Total number of students and teachers who rode to the zoo in buses $=55*7=385$

Total number of students and teachers who rode to the zoo in vans $=12*2=24$

<span>Congruence between two triangles means six items, all three sides and all three angles, are congruent. Thus the statement ABC DEF has a very precise meaning. It succinctly summarizes the six statements (assume lines atop these segments): ABDE, BCEF, ACDF, AD, BE, and CF. It is very important to maintain the vertices in the proper order. Not doing so is a common mistake.</span>

Put it in an equation;
it is given that 36 is the price after the 40% discount, so;
36=X*40%
X here is the original price
