Lets simplify this problem. 15-10=5, so 1x=5 , 2x=10 and x = the number of days, so 2 days.
note: f=fruit
y=yoghurt
2:3
f : y
f/y=2/3
=> 3*f=2*y
f=(2*y)/3
we know that f+y=185g
(2*y)/3+y=185g
(2*y+3*y)/3=185g
5*y/3=185
y=(185*3)/5
y=111g
=>the mass of the yoghurt is 111 g
Answer:
1600
Step-by-step explanation:
1600 x 0.05 = 80
or
80 / .05 = 1600

U have selected the correct answer..... Option 3rd is the correct
Answer:
- boat: 6 mph
- current: 2 mph
Step-by-step explanation:
The relationship between time, speed, and distance is ...
speed = distance/time
For boat speed b and current speed c, the speed downstream is ...
b +c = (16 mi)/(2 h) = 8 mi/h
The speed upstream is ...
b -c = (16 mi)/(4 h) = 4 mi/h
Adding the two equations eliminates the c term:
2b = 12 mi/h
b = 6 mi/h . . . . . divide by 2
Solving the second equation for c, we get ...
c = b -4 mi/h = 6 mi/h -4 mi/h = 2 mi/h
The speed of the boat in still water is 6 mi/h; the current is 2 mi/h.
