Assuming that the numbers are right next to each other, we have
(x)*(x+1)=156, expanding into x^2+x=156 and then x^2+x-156=0. We can then use the quadratic formula to get x=(-1+-sqrt(1+624))/2=(-1+-25)/2= 12, -13. -13 wouldn't be a page number, so 12 must be one number, and 12+1 (13) is the other!
The answer is 700 meters
why?
1. km=1000.m so when you move the 1 to the right .1 you have to do the same woth 1000. which will be 100.0
the answer is 20
why?
1 quart=4 cup so change 1 to 5 which means *5 and the same with cups 4 to 20 which means *20
Answer:
245 pounds in 7 days
Step-by-step explanation:
35 pounds= 1 day for one person
35*7=245
-5y+6x=40
.75(3y-8x)=.75(46)
-5y+6x=40
2.25y-6x=34.5
-2.75y=5.5
Y=-2
———
3(-2)-8x=46
-6-8x=46
+6 +6
-8x=52
X=-6.5
(-6.5,-2) is the answer
