Answer:
Slope: -3/4
y-intercept: (0,-5)
Step-by-step explanation:
Graph the line using the slope and y-intercept, or two points.
Step-by-step explanation:
b=a-80
c=b-61
c=a-141
a+b+c=3a-221=430
3a=651
a=217 & b =137 & c=76
6 students were in class because the 5 represents on how many groups you need to have
Answer:
(5c-d)/a = b
Step-by-step explanation:
First you would bring the d to the right side of the equation
ab=5c -d
Then, you will divide the right side of the equation by a to find the value of b
(5c-d)/a =b
Hope this helps!!!
