first you take 1134 times 5 and get 5670(joe bob and Billy together) then 337 times 5 gets you 1885 which is bobs number hope I helped:)
S1 = speed of boat 1
<span> t1 = time to do 1400 meters (boat 1) </span>
S1*t1 = 1400
<span><span>S2 </span>= speed of boat 2 </span>
1400 + S2*t1 = X
t2 = time to do X + 600 (boat 2)
S1*t2 = X + 600
S2*t2 = 2X - 600
S1 = 1400/t1
S2 = (X-1400)/t1
<span>T = t2/t1 </span>
1400*T = X + 600
X*T - 1400*T = 2X - 600
X = 3600 meters
<span> River is 3600 meters wide</span>
Answer:
-3=x
Step-by-step explanation:
First you must add the X's on each side which gives you: 1x-2= -x - 4 - 4
Next you must add the first number 4 to the - 2 on the other side.
Then you do the exact same thing with the other number 4.
After that you get 1x+6=-x, then you subtract the 1 x with the -x to get 6= -2x.
Finally divide both sides by 2 and your final answer is -3 = x
Answer:
18π or 56.5 (1 d.p) feet squared
Step-by-step explanation:
As the formula for the area of a semi circle is πr²/2 as the area of a circle is πr² so the area would be 18π or 56.5 (1 d.p)
