Question:

Brian, Chris, and Damien took a math test that had 20 questions. The number of questions Brian got right is 14 more than 1/4 the number of questions Chris got right. Damien correctly answered 2 less than 5/4 the number of questions Chris answered correctly. If Brian and Damien have the same score, which statement is true?

A) Brian and Damien both answered 2 fewer questions correctly than Chris did.

B) Brian and Damien both answered 4 more questions correctly than Chris did.

C) Brian and Damien both answered 2 more questions correctly than Chris did.

D) Brian and Damien both answered 4 fewer questions correctly than Chris did.

Answer:

Option C

Brian and Damien both answered 2 more questions correctly than Chris did

Solution:

Let "x" be the number of correct answers of Brian

Let "y" be the number of correct answers of Chris

Let "z" be the number of correct answers of Damien

The number of questions Brian got right is 14 more than 1/4 the number of questions Chris got right

$x = 14 + \frac{1}{4}y\\$ ---------- eqn 1

Damien correctly answered 2 less than 5/4 the number of questions Chris answered correctly

$z = \frac{5}{4}y - 2$ ---------- eqn 2

Brian and Damien have the same score

x = z -------- eqn 3

Therefore,

$14 + \frac{1}{4}y = \frac{5}{4}y - 2\\\\\frac{5}{4}y - \frac{1}{4}y = 14+2\\\\y = 16$

Substitute y = 16 in eqn 1

$x = 14 + \frac{16}{4}\\\\x = 14 + 4\\\\x = 18$

Therefore, by eqn 3,

z = 18

Thus we get,

Number of correct answers of Brian = 18

Number of correct answers of chris = 16

Number of correct answers of Damien = 18

Therefore, correct statement is:

Brian and Damien both answered 2 more questions correctly than Chris did

How would i solve this (-4,2); m=1/2

Setler [38]

Answer:

I'm pretty sure you have to do slope intercept form so it would be like this.

Y= mx+b

M is 1/2 and the X is given in the ordered pairs. Y is also given but it counts as the intercept so it is actually the 'B' of the equation. YOu just have to fill it in.

Y= 1/2(-4) + 2
