Dear Samanthamunevar
The one in the thousands is 100 times greater than the one in the tens
Hope this helps!
Area of chalkboard = 4 feet x 6 feet = 24 square feet.
Total cost = 24 square feet x $7.21 per square foot = $173.04
Answer: $173.04
This is slope-intercept form y=mx+b
when you substitute it, it becomes y=6x-3
X= 30/r is the answer because if you divide both sides by r you are left with x=30/r because you cant divide 30 by r
