6. a group of 280 elementary school students and 40 adults are going on a field trip.

they are planning to use two different types of buses to get to the destination. the

first type of bus holds 50 people and the second type of bus holds 56 people,

andre says that 3 of the first type of bus and 3 of the second type of bus will hold all

of the students and adults going on the field trip. is andre correct? explain your

reasoning

No because the buses are short 2 seats.

Step-by-step explanation:

280 students + 40 adults = 320 people

Bus type A holds 50 people

Bus type B holds 56 people

3 x 50 = 150 seats available for type A

3 x 56 = 168 seats available for type B

3a + 3b = c

3(50) + 3(56) = c

150 + 168 = 318

The buses seat 318 people and cannot accommodate 320 people.

the amount you'd have after the work is $1.55

step-by-step explanation:

you subtract 95% from $31.

the solution is the point

step-by-step explanation:

we have

> equation a

> equation b

adds equation a and equation b

substitute the value of x in equation b to find the value of y

the solution is the point
