(16/18)
(24/27)
You just times 8 and 9 by the same number, like:
(8•2/9•2)=(16/18)
(8•3/9•3)=(24/27)
You could do any number:
(8•100/9•100)=(800/900)
Let the rate of the current be x mph and rate of the boat in still water be y mph.
So the relative speed of the boat with the current ( downstream) = y + x and against the current (upstream) it = y - x.
Then , using speed = distance / time:-
y - x = 120/3 = 40
y + x = 120/2 = 60
Adding the 2 equations:-
2y = 100
y = 50
And substituting in the frst equation:-
50 - x = 40
x = 10
Answer:- Rate of boat in still water = 50 mph and rate of the current = 10 mph.

<em><u>10 subtracted from the quotient of a number and -3 is at least -1 is:</u></em>
<em><u>Solution:</u></em>
<em><u>Given statement is:</u></em>
10 subtracted from the quotient of a number and -3 is at least -1
Quotient means reuslt of dividing two numbers
Let the number be "x"
quotient of a number and -3 =
Therefore,
10 subtracted from is at least -1
at least means "less than or equal to"
<em><u>Which is translated into algebraic expression as:</u></em>
<em><u>Solve the above inequality</u></em>
When we multiply or divide by negative number. we have to flip the inequality sign
Thus the solution of inequality is found
Step-by-step explanation:
Longest side is between 36 and 18 feet
18 < L < 36
IF longest side were 36 feet, width =0
IF longest side were 18, then width = 18
to be longest L>W L>18. and L can't be as much as 36 to keep width >0
