Answer:
4
Step-by-step explanation:
1. Divide total number of students by number of students per car (use remainder rather than decimal)
13/4 = 3, remainder 1
In this case, round up because no student can be left behind. 4 cars will be used.
Answer:
0.41
Step-by-step explanation:
0.82 = 0.2 x 0.41

= ( 0.2 x 0.41 ) / 0.2
= 0.41
Answer:
C. 21
Step-by-step explanation:

Answer:
a₁ = -5, d = 7, a₂ = 2, a₃ = 9, a₄ = 16
equation of sequence: 
Step-by-step explanation:
a₁ + a₂ + a₃ = 6
a₁ + a₁ + d + a₁ + 2d = 6
3a₁ + 3d = 6
a₁ + d= 2 ⇒ a₁ = 2 - d
a₄ = 16
a₁ + 3d = 16
2 - r + 3d = 16
2d = 14
d = 7
a₁ = 2-7 = -5
a₁ = -5, d = 7 ⇒ a₂ = -5+7 = 2, a₃ = 2+7 = 9, a₄ = 9+7 = 16
equation of arithmetic sequence:
