A large community college has professors and lecturers. The total number of faculty members is 136. The school reported that they have 6 professors for every 11 lecturers. How many professors does the community college employ?

Answers

answer : 125
explain: none

Answer:

48 professors

Step-by-step explanation:

First, add 11 + 6 = 17

Here is what I did after that,

136 / 17 = 8

I divided 136 by 17 because for every 11 lecturers there are 6 professors, and to get the total amount of how many times there are 6 professors and 11 lecturers.

After that, you would multiply 8 * 6, since there are 6 professors.

So, the answer that I got would be 48.

MARK BRAINLIEST AND 12 POINTS

Answers

Answer:

17

125

Step-by-step explanation:

exterior angle is equal to sum of interior opposite angle. so

( 2x + 6 ) + ( 5x ) = ( 8x - 11 )

7x + 6 = 8x - 11

x = 17

exterior angle = ( 8 * 17 ) - 11 = 125

Your answer would be 17 and 125

Hello I can help you what is the math question you ask so I can help you get an A

Answer:  these are in "slope-intercept form"  y = mx + b

m is the slope.  b is the y-intercept

Start with the y- intercept, the "constant" on the right side of the equation. Plot a point there on the y-axis. Then use the slope to plot another point or two to find our where to draw the line. If there is no number for m, it is an implied 1. That means from your first point, go up 1 then 1 to the right to plot the next point

Step-by-step explanation:

When the slope is a fraction, use the denominator to find out how far to go to the right.

If the slope is negative, move down first then to the right to plot the next point.

The answer it’s 16 because when you supract 25 by 9 it’s will give you 16 and the p =q so q also 16
The correct answer is C) substitution property of equality.
