Each of the 7 busses that were used for the field trip contained the same number of students as well as 8 chaperones. write an expression for the total number of people going on the field trip. (let x represent the number of students on each bus).

7x+8

Step-by-step explanation:

7 buses containing x students each and 8 chaperones

5=812a+9+3

step 1: simplify both sides of the equation.

5=812a+9+3

5=(812a)+(9+3)(combine like terms)

5=812a+12

5=812a+12

step 2: flip the equation.

812a+12=5

step 3: subtract 12 from both sides.

812a+12−12=5−12

812a=−7

step 4: divide both sides by 812.

812a /812 = -7/812

a= -1/116

so the answer is

a=   -1/116

3 3 6, because in every triangle the longer side is always shorter than the sum of the other two
