There was 3 erasers in each pack because 2 times 3 is 6 plus 2 equals 8. so there are 3 in each pack.
The unit rate is 2/3 because in the line y=2/3x, 2/3 is the slope (y=mx+b). The slope of the line is pretty much the definition of a unit rate because the unit rate is a constant addition or subtraction over and over. In addition, it is a straight line(y=mx+b) and the values are going up at a constant rate of 2/3.
Answer:
17
Step-by-step explanation:
f(5)=3*5+2 where X is equal to 5
X+(x+1)+(x+2)+(x+3)+(x+4)+(x+5)=393
6x+15=393
6x=393-15
6x=378
x=63
third one is 63+2=65
We can use the equation 45m < 481
we can replace m to see where it caps.
and the cap is 10.
we can replace m to check our work
45(10) < 481
450 < 481
if you add another student, it would go over the limit.
hope this helps :D
