Answer:1:10 (simplified from 4:40)
Step-by-step explanation:
4 pencils + 12 markers + 24 crayons = 40 total items
4 pencils : 40 items
1 pencil : 10 items

Answer:
a. 6
b. 12
c.
Step-by-step explanation:
a. Using two pairs of values given, (0, 12) and (1, 18)
Rate/slope =
Unit rate/slope (m) = 6
b. The starting value is the y-intercept (b). It is the value of of y when x = 0.
From the table, when x = 0, y = 12.
Therefore the starting value (b) would be 12.
c. The equation can be written in slope-intercept form, , where,
m = slope/rate = 6
b = starting value/intercept = 12.
Plug in the values into the equation
The equation would be:

This questions expects us to SOLVE for S, i.e. express the the value of S in terms of other variables, and simplify the answer, if necessary.
We need s to be the subject (on the left hand side), so we need to isolate s.
C=(1/3)m(s+b)
First step, cross multiply to rid of numerical fractions.
C/1=(m(s+b))/3 -> 3C=m(s+b)
If there is a multiplier that does not contain s, divide both side by the multiplier.
3C/m = (m/m)(s+b) -> 3C/m = s+b
We're nearly done. We need to isolate s, so subtract "extra" terms from the side containing s, i.e. subtract b from both sides:
3C/m - b = s + b -b -> 3C/m-b = s
We almost there, but customary practice is to put s on the left-hand side of the equal sign, so just swap sides:
3C/m-b = s -> s=3C/m - b
and that's the answer:
s=3C/m - b
Basically it’s r=c/2pi meaning it’d be r=62/2(3.14) which would give you r=9.87
