Answer: n=5.666667

Step 1: Simplify both sides of the equation.

0.3(n−5)=0.4−0.2

(0.3)(n)+(0.3)(−5)=0.4+−0.2(Distribute)

0.3n+−1.5=0.4+−0.2

0.3n−1.5=(0.4+−0.2)(Combine Like Terms)

0.3n−1.5=0.2

Step 2: Add 1.5 to both sides.

0.3n−1.5+1.5=0.2+1.5

0.3n=1.7

Step 3: Divide both sides by 0.3.

0.3n/0.3 = 1.7/0.3

n=5.666667

PLEASE HELP ME. :( :(

Y = mx + b

4 = m(248) + b
6 = m(372) + b
subtract the two equations to get
-2 = m(-124) + 0
m = 1/62

Then plug in m into one of the equations to find b
4 = (1/62)(248) + b
4 = 4 + b
b = 0

So the equation is
y = (1/62)x + 0
or
y = (1/62)x
or
y = x/62

edit: I totally didn't use point slope. It should be
y + 0 = (1/62)(x + 0)
or y = (1/62)x

(since b is 0, that means she started driving directly at home)

13 lbs shared between 3 batches . . .

13/3 = 4 1/3 lbs each

The two whole numbers would be 4 and 5
