<span>erry starts rowing at 2 pm from the west end of the lake, and Tao starts rowing from the east end of the lake at 2:05 pm.
------
Terry DATA:
rate = 60 meter/min ; time = x min ; distance = r*t = 60x meters
-----
Tao DATA:
rate = 40 meter/min ; time = x-5 min ; distance = r*t = 40(x-5) meters
--------------------------
If they always row directly towards each other at what time will the two meet?
------
Equation:
dist + dist = 2000 meters
60x + 40(x-5) = 2000
20x = 1800
x = 90 minutes

Answer:
x > -2
Step-by-step explanation:
-3x + 12 < 18
Subtract the 12 from both sides and you'll get:
-3x < 6
Divide by -3
x > -2
You flip the sign when you mulitply by a negative number
Hopefully this helps, sorry if it doesn't
Answer:
$33.60
Step-by-step explanation:
multiply 40 by 0.20 = 8 subtract 8 from 40= 32 x 0.05 is 1.6 so its 33.6
after 1 year he will get : 800 + 800 x 3,5% = 800 x 1,035 = $828
after 2 years he will get : 828 x 1,035 = 800 x 1,035 x 1,035 = 800 x 1,035²
so
after n years he will get : 800 x 1,035ⁿ
3 and 3/4lb=20.25
what you should do is divide both sides by 3 and 3/4 but that isnt nice
convert 3 and 3/4 to improper
3 and 3/4=3+3/4=12/4+3/4=15/4
15/4lb=20.25
times 4/15 to both sides (15/4 times 4/15=60/60=1)
1lb=81/15
1lb=5.4
answer is
1lb=$5.40
