The oldest cousin should be 10. If their ages are consecutive even whole numbers, then the younger cousins should be 2 & 4. 2+4=6+10=16
Did you mean 9 - 20 will if u did it equals up to -11
12 1/3 x 4.5 = 55 1/2 feet
-200 + 55 1/2 = -144 1/2
the diver is at -144 1/2 feet
3x-4= - 10
add both side 4 so its a addition property
3x=- 6
now divide both side 3 so it is a <span>division property.
so x=-2</span>
