Answer:
<h3>c = 2</h3>
Step-by-step explanation:
The value of the fraction 3c+2/4 one less than the value of the fraction 5c-1/3 is expressed as;
(3c+2)/4 = (5c-1)/3 - 1
We are to calculate the value of c as shown;
(3c+2)/4 = (5c-1)/3 - 1
(3c+2)/4 = [(5c-1) - 3]/3
(3c+2)/4 = 5c-4/3
Cross multiply;
3(3c+2) = 4(5c-4)
9c + 6 = 20c -16
9c - 20c = -16 -6
-11c = -22
c = 22/11
c = 2
Hence the value of c is 2
I still need that 10 points tho
r+b =12
r =2b (twice as many red as blue)
substitute r = 2b into r+b=12
2b + b = 12
3b =12
divide by 3
b=4
r = 2b
r=2(4)
r=8
There are 4 blue pencils and 8 red pencils

So, we have:



-- approximated
Y-2=-3/2(x-2)
first of all, the slope of the line is -3/2, and there's only one equation that has that as a choice for the slope. Then you can take the x and y coordinates given in that equation you want to check and see if the line goes through that point. from the equation, (point-slope form y-y=m(x-x)) I know that the line should pass through point (2, -2), and looking at the graph, that is correct.
