Answer:
There were 3 cars and 9 buses used for the field trip.
Step-by-step explanation:
Let the number of cars be x
and Number of buses be y.
Total number of vehicles used = 9
Hence,
Also
Each Car carries students = 4
Each Bus carries students = 35
Total Students = 222
Hence,
Now multiplying equation 1 by 4 we get;
Now Subtracting equation 3 from equation 2 we get;
-(4x+4y) =222-36\\4x+35y-4x-4y=186\\31y = 186\\y = \frac{186}{31} = 6](https://tex.z-dn.net/?f=4%28x%2By%29%3D%204%5Ctimes%209%20%5C%5C%5Btex%5D%284x%2B35y%29-%284x%2B4y%29%20%3D222-36%5C%5C4x%2B35y-4x-4y%3D186%5C%5C31y%20%3D%20186%5C%5Cy%20%3D%20%5Cfrac%7B186%7D%7B31%7D%20%3D%206)
Now y = 6
∴ x + y = 9 (Given)
x + 6 = 9
x = 9 - 6
x = 3
Hence, There were 3 cars and 9 buses used for the field trip.

Answer:
The given expression consists of 2 factors, and each factor contains 3 terms.
Step-by-step explanation:
Given the expression (a+b+c)(d+e+f)
Factors are parts of expression that are connected by multiplication. we are multiplying (a+b+c) and (d+e+f) so we said (a+b+c) and (d+e+f) are factors of the expression.
Hence, there are 2 factors in given expression.
A mathematical expression contains numbers, variables and operators joined by addition, subtraction, multiplication, and division. The parts of the expression that are connected with addition and subtraction are known as terms.
In each factor (a+b+c) and (d+e+f) three terms are connected by addition. Hence, there are 3 terms in both the factors.
