Answer:
B) addition property
Step-by-step explanation:
thinking that 3x - 30 - 0 should equal 0.
3x - 30 - 0 = 0
to get rid of numbers on side with variables, we have to add them to both sides (to make it 0 in side with variable.)
3x - 30 - 0 = 0
+30 +0 = +30 +0
3x = 30 <- step 4
To find the difference, we need to subtract the height of the fish from the height of the bird. If we use sea level as 0, then the bird flies at 1,281 feet, and the fish swims at -282 feet.
1,281 - (-282) = <span>1,281 + 282 = 1,563 feet
There is a </span><span>1,563 feet difference between the height of the bird and the depth of the fish</span>
Both formulas equal to y, so they are equivalent to one another.
3x-5 = -3x+4
+5. +5
3x = -3x+9
+3x. +3x
6x = 9
/6. /6
x = 1.5
3(1.5)-5 = y
4.5-5
y = -0.5
B because absolute value means the distance of a point on a number line from 0. So the absolute value of -6 is 6 and you add that to 4
Are you asking how much money was added? Because if you are then you would just subtract and get 25
