, Cooper will volunteer at the community food bank? (1 point)
Responses

h2 = 3.5
Start Fraction h over 2 End Fraction equals 3.5

3.5h = 14
3.5 h equals 14

h14 = 3.5
Start Fraction h over 14 End Fraction equals 3.5

h3.5 = 2

Answer 2

Vicky bought 312 pounds of oranges. Each pound costs $3.90. Which of the following equations represents the total cost, c , Vicky paid for the oranges and the amount of money she spent?(1 point)

Responses

c3.5=3.90; Vicky paid $13.65.
Start Fraction c over 3.5 End Fraction equals 3.90 ; Vicky paid $13.65.

3.90c=3.5; Vicky paid $0.90.
3.90 c equals 3.5 ; Vicky paid $0.90.

3.903.5=c; Vicky paid $13.65.
Start Fraction 3.90 over 3.5 End Fraction equals c ; Vicky paid $13.65.

c3.90=3.5; Vicky paid $1.11.

Question

A culture of a certain bacteria doubles every hour. At 9:00 a.m, there were already 120 bacteria. Which equation represents the number of bacteria, n, at 8:00 a.m? How many bacteria were there?(1 point)
Responses

2n=120; at 8:00 a.m., there were 60 bacteria.
2 n equals 120 ; at 8:00 a.m., there were 60 bacteria.

n2=120; at 8:00 a.m., there were 60 bacteria.
Start Fraction n over 2 End Fraction equals 120 ; at 8:00 a.m., there were 60 bacteria.

n2=120; at 8:00 a.m., there were 240 bacteria.
Start Fraction n over 2 End Fraction equals 120 ; at 8:00 a.m., there were 240 bacteria.

2n=120; at 8:00 a.m., there were 240 bacteria.
