1944
s(n) = s(n-1)*s(n-2)
18 = 3 * 6
108 = 18 * 6
1944 = 108 * 18
Answer: For triangle: a line starting on the left corner going to the middle of the triangle. Hopefully that helps for the blank question
The answer is 70. You can obtain this by dividing the number by its percentage, and 56 is 80 percent of 70. I hope this helped, have a nice day! =)
Answer:
Step-by-step explanation:
The answer is <span>twelve sevenths (12/7)
</span>
x - the job<span>
t - time to do the job x
</span><span>Robin can mow a lawn in 3 hours: x/3 * t
</span><span>Brady can mow the same lawn in 4 hours: x/4 * t
</span><span>If they work together, the total work will
be the sum of their speeds:
</span>x = x/3 * t + x/4 * t = (x/3 + x/4)*t = (4x/12 + 3x/12) * t = 7x/12 * t
x = 7x/12 * t
Divide both sides by x:
x/x = 7x/12 * t/x
1 = 7/12 t
t = 1 : 7/12
t = 12/7
