: Twice a number is 220 less than six times the number. What is the number?
The Coastline of California is 46 miles longet than twice the leght of louisiana's coastline. It is also 443 miles longer than Louisiana's coastline. Find the lengths of the coastlines of california and louisiana.
An empty bucket is put under two faucets. If one faucet is turned on alone the bucket fills in 6 minutes. If the other faucet is turned on alone, the bucket fills in 4 minutes. If both are turned on, how many seconds will it take to fill the bucket This question is from textbook Pre-Algebra
You can put this solution on YOUR website! 2X=6X-220
2X-6X=220
-4X=220
X=220/-4
X=-55 ANSWER.
PROOF
2*-55=6*-55+220
-110=-330+220
-110=-110
-------------------------------------------
C=2L+46
C=443+L NOW SUBSTITUTE (443+L) FOR C IN THE FIRST EQUATION & SOLVE FOR L
443+L=2L+46
L-2L=46-443
-L=-397
L=397 ANSWER FOR THE LOUISIANA COASTLINE.
C=2*397+46
C=794+46
C=840 ANSWER FOR THE CALIFORNIA COASTLINE.

4*6/(4+6)
24/10=2.4 MINUTES TO FILL THE BUCKET USING BOTH FAUCETS.
