If 1 cm represents 300,000 cm
Then 4.3cm = (4.3)(3000,000cm) = 1,290,000cm = 12.km
15 - 13.375 = .75x
1.625 = .75x divide both sides by .75
2.16 = x
He can carry 2 bottles
2 + 2/5 = 2.4
sqrt(2.4) = about 1.5492
-48 / -24 = 48 / 24 = 2
Let Brad's age = x then Corey's = 2x
And we know that
x + 2x = 54 simplify
3x = 54 divide both sides by 3
x = 18 this is Brad's age
2x = 2(18) = 36 this is Corey's age
(New Length) x (New Width) = (New Area) ..... so......
8(1.20) x 8(1.25) = 96 cm^2
4392 - 93 = 4299 above sea level
The amount of the tax is :
24 X .08 = $1.92
So.....adding this to $24 we get the total cost of $25.92
So.....he has enough to buy the gift
I haven't used this method, but it looks good........here's a link that explains how to do it......

-5 > 4
-8 > 7
Both are incorrect..........4 is to the right of -5 on the number line......thus...it's greater than -5
The same reason holds for 7 and -8
