Step-by-step explanation:
w1*h1*d1=w2*h2*d
15*8*20=10*6*d
2400=60d
d=2400/60
d=40
Answer:
y =8
Step-by-step explanation:
Answer:
14 = x
Step-by-step explanation:
-2 on both sides you get 7 = x/2, multiply both sides by 2 and you get 14 = x
-3(2r+7)=3
distribute -3
-6r-21=3
add 21 to both sides, this causes the 21 on the left to cancel itself out.
-6r=24
divide each side by -6, this causes the -6 on the left side to cancel itself out.
r=-4
it will take the duck 5.8 seconds to reach 29 feet of depth.
