Answer:

220

Step-by-step explanation:

Given that the freshman class has 160 students.

Each freshman must write three reports from a list of 12 novels that the teacher has assigned them to read

Here order does not matter.  Hence combinations can be used.

No of available options  = 12

No to be selected =3

Possible number of ways = ways of selecting 3 from 12 where order does not matter

= 12C3\\=\frac{12(11)(10)}{6} \\=220

Option B is right answer.

Solve the formula Ax+By = C for A.
jok3333 [9.3K]

Answer:

A = \frac{C - By}{x}

Step-by-step explanation:

Given

Ax + By = C

Required

Solve for A

The question implies that we make A the subject of the formula.

Start by subtracting By from both sides of the equation by x

Ax + By - By= C - By

Ax = C - By

Divide both sides by x

\frac{Ax}{x} = \frac{C - By}{x}

A = \frac{C - By}{x}

<em>Solved</em>

In equilateral △ABC, y = ?
Nina [5.8K]
Well since it’s equilateral then we know that x+3x+2x=180/3=6
So 6x=6 x=6
Angle ACB is gonna be 60 degrees (bc it’s equilateral)
So we can do 3x+2x+60+y=180
So we have 3+2+60+y=180
So y will equal 115
