Answer:  3 students picked a vanilla cupcake.

Step-by-step explanation:

Hi, to answer this question we have to analyze the information given:

  • <em>Number of students that took a cupcake: 12 </em>
  • <em>Percentage of students that took a vanilla cupcake: 25% </em>

So, to obtain the number of students that picked a vanilla cupcake we simply have to multiply the number of students (12) by the percentage that took the vanilla ones. (25 %, in decimal form 25/100 =0.25)

Mathematically speaking:

12 x 0.25 = 3

3 students picked a vanilla cupcake.

Feel free to ask for more if needed or if you did not understand something.

2. Create a linear function that has a rate of change of 3 and a solution at (6, 12).
Ksivusya [100]

Answer:

y = 3x - 6

Step-by-step explanation:

A linear function has the following format:

y = ax + b

In which a is the slope(rate of change) and b is the y-intercept, that is, the value of y when x = 0.

Rate of change of 3

This means that a = 3

So

y = 3x + b

A solution at (6, 12).

This means that when x = 6, y = 12. So

y = 3x + b

12 = 3*6 + b

b = -6

The linear function is:

y = 3x - 6

1..) 2x +15 = 35 
Masja [62]

Answer:

1) x=10

2) x=3

Step-by-step explanation:

1)

2x+15=35

Subtract 15 from both sides

2x=20

Divide both sides by 2

x=10

2(10)+15=35

20+15=35

35=35

this shows that 10 is the right answer

2)

7x-3=18

Add 3 to both sides

7x=21

Divide both sides by 7

x=3

7(3)-3=18

21-3=18

18=18

this shows that 3 is the right answer

Hope this helps

All you have to do is multiply 1/5 x 3 for the three days Monday, Tuesday and Wednesday and that gets you 3/5 or as 1/5 of a km is 0.2 you have to multiply 0.2 x 3 and you get 0.6 which is equivalent to 3/5
