OK, so I think you divide 30 by 310 which would be... 1 R 10 or fraction one and one-third 1 1/3 Does this help?

Answer:

93 students

Step-by-step explanation:

We need to calculate the 30% of 310 students.

We can calculate with a direct rule of 3 . If the 100% is 310 students, how many students are the 30%?

x = 93

Answer:B

Step-by-step explanation:

Answer: x=1 ==> D

Step-by-step explanation:

Lets say y=180-43x

Hence, 2y=272x+2

y=180-43x

2y=360-86x

360-86x=272x+2

360=272x+88

272x=272

x=1 ==> D

Answer:

A is the answer of above question

In function notation, we write f(x) when x is the input or independent variable.

In this case, x is the independent variable and y is teh dependent variable (y =f(x)).

Then, the right way to write this equality in function notation is f(x)=3x²+2
