At a company meeting, there were 996 people in attendance. 25% of them were managers. How many managers were in the meeting?

nalin [4]

They are asking for managers so 996 of them are there, 25% are managers

Change the percent to a decimal (divide the percent number by 100)

You get 0.25

So multiply 996 by 0.25

You get 249

So there are <u>249 managers at the meeting</u>

Y=3x+62x+4y=−4 What is the value of y in the system?

Marrrta [24]

Answer:

y = 0

Step-by-step explanation:

We assume you want to find y such that ...

y = 3x +6
2x +4y = -4

Dividing the second equation by 2, we can write an expression for x.

x +2y = -2

x = -2y -2

Substituting this into the first equation gives ...

y = 3(-2y -2) +6

y = -6y -6 +6 . . . eliminate parentheses

7y = 0 . . . . . . . . . add 6y

y = 0 . . . . . . . . . . divide by 7

The value of y in the system of equations is 0.
