1) 331 students went on a field trip. Six buses were filled and 7 students traveled in cars. How many students were in each bus?

2) Aliyah had $24 to spend on seven pencils. After buying them she had $10. How much did each pencil cost?

3. 6a + 5a = −11
4. −6n − 2n = 16
5.4x + 6+ 3 = 17
6.0 = −5n − 2n
7. 6r − 1 + 6r = 11
8. r + 11 + 8r = 29
9. −10 = −14v + 14v
10. −10p + 9 p = 12
11. (7 − 2) ÷ 5
12.5 + (16 + 2) ÷ 3
13.2 + 12 ÷ 2 + 1
14.−3 × 2 × 2(−3 − 1)
15. ((−16 − (−2 + 1)) × 2) ÷ 5

8

step-by-step explanation:

to find the amount of gift bags to use all the supplies, find the gcf or greatest common factor. this is the largest number which multiplies evenly into each term.

48 has factors: 1, 2, 3, 4, 6, 8, 12. 16, 24, 48

80 has factors: 1, 2, 4, 5, 8, 10, 16, 20, 40, 80

64 has factors: 1, 2, 4, 8, 8, 16, 32, 64

the highest number factor they all share in common is 8. this means there will be 8 bags with 6 pencils, 10 markers, and 8 stickers in each bag.

step-by-step explanation:

assume that you have 3 different side lengths.   apply the pythagorean theorem here:   square each of the two shortest sides; call them a and b, so that their squares are a² and b².   also square the longest side, calling the result c².

now, if a² + b² = c² is true, the triangle is a right triangle; otherwise it is not a right triangle.
