6
:
3 • (a + 4)
————————————————— = 0
(a + 3) • (a - 3)
3•(a+4)
——————————— • (a+3)•(a-3) = 0 • (a+3)•(a-3)
(a+3)•(a-3)
a+4 = 0
Subtract 4 from both sides of the equation :
a = -4
Answer:
2 3/8
Step-by-step explanation:
If what you're saying it 3 1/8 - 3/4 then...
3 1/8 - 3/4
3 1/8 - 6/8
25/8 - 6/8
19/8
2 3/8
Answer:
Step-by-step explanation:
S = second; F = flying time.
Since it can flap its wings 30 times, each second, we have already found our answer. The relationship between flying time (Wing flaps) and seconds is 30. In other words, it beats it's wings 30 times each second. Which is what the question asks.
Now we just have to write the equation:
This is because the seconds are <u>dependent</u> on the flap of wings, so s would be the y value.
