1. (29 + 19) ➗ 3

(48) ➗ 3

48➗ 3

There are 16 cards in each pile

Step-by-step explanation:

2. 14 3. 110 4. 71 5. 54 6. 16 7. 23

8. 75 9. 32 10. 22 11. 20 12. 48 13. 53

14. Spit 6 in half to get Melinda's length so the answer is 3

15. No the answer is not the same because you have to minus 18 to 8 (which is in the parenthesis) so the answer is 10. But the other way around you have to add 15 (which is in the parenthesis) plus 5.

I really hope I helped you

A school district transported a total of 409 students and teachers to a zoo in buses and vans.

valina [46]

Answer: There are 385 students and teachers who rode to the zoo in buses and 24 students and teachers who rode to the zoo in trains.

Step-by-step explanation:

Since we have given that

Total number of students and teachers = 409

Let the number of vans be x

Let the number of buses be x+5

Number of students and teachers each bus transported = 55

Number of students and teachers each van transported = 12

According to question,

$55(x+5)+12x=409\\\\55x+275+12x=409\\\\67x=409-275\\\\67x=134\\\\x=\frac{134}{67}\\\\x=2$

Total number of students and teachers who rode to the zoo in buses will be

$55(x+5)\\\\=55(2+5)\\\\=55\times 7\\\\=385$

Total number of students and teachers who rode to the zoo in vans will be

$12x\\\\=12\times 2=24$

Hence, there are 385 students and teachers who rode to the zoo in buses and 24 students and teachers who rode to the zoo in trains.
