7 + 5 + 2 = 14 because seven plus five is twelve, twelve plus two is fourteen.
Answer:
A is bigger
Step-by-step explanation:
lets say the certain number is 10 and if its 20% of Number A that would mean that number A is 50 and that would also mean that number B is 25 so since 50 is bigger then 25 that would mean number A is bigger
Answer:
134
Step-by-step explanation:
938÷7=134
3x - y + z = 5 . . . (1)
x + 3y + 3z = -6 . . . (2)
x + 4y - 2z = 12 . . . (3)
From (2), x = -6 - 3y - 3z . . . (4)
Substituting for x in (1) and (3) gives
3(-6 - 3y - 3z) - y + z = 5 => -18 - 9y - 9z - y + z = 5 => -10y - 8z = 23 . . (5)
-6 - 3y - 3z + 4y - 2z = 12 => y - 5z = 18 . . . (6)
(6) x 10 => 10y - 50z = 180 . . . (7)
(5) + (7) => -58z = 203
z = 203/-58 = -3.5
From (6), y - 5(-3.5) = 18 => y = 18 - 17.5 = 0.5
From (4), x = -6 - 3(0.5) - 3(-3.5) = -6 - 1.5 + 10.5 = 3
x = 3, y = 0.5, z = -3.5
V = Bh ⇒
h = V/B = 1122 / 93.5 = 12 inches.
