Let the speed of current be x km/ hr 
Upsetram  = ( 6.5 -x) km/ hr
Downstram = ( 6.5 + x) km/ hr 
Distance = Speed x Time 

5 ( 6.5-x) = 2 ( 6.5+x) 
32.5 -5x =13 +2x 
7x = 19.5 
x =2.7857142 km/ hr 
ANSWER: 2.79 km/ hr

tekilochka [14]

Answer:

1.2 x 10⁴

Step-by-step explanation:

12,000 has 2 places of other numbers before a spam of zeroes.

Last digit is 2 so a decimal goes before 2

1.2

Count how many places the decimal moved: this number is your power of 10.

12000.  --> 1.2000

It moved 4 places.

12,000 = 1.2 x 10⁴

Gnoma [55]

Answer:

Equation: 20=4x or x=\frac{20}{4}

Solution: x=5

Step-by-step explanation:

The formula that is used to calculate the perimeter of  a square is:

P=4s

Where "s" is the side lenght the square.

Knowing that Xin used  20 yards of fencing to build the walls of a square chicken coop (in which the lenght in yards of each wall is represented with "x"), you can identify that:

P=20\\\\s=x

Then, you can susbtitute values into the formula P=4s:

20=4x

Finally, you must solve for "x" in order to find its value.

This is:

\frac{20}{4}=x\\\\x=5

Answer:

56°

Step-by-step explanation:

First, the measure of angle GHE is equal to DFH. This means that you can set 98-6x=63-x, which becomes 5x=35 so x=7. Substitute 7 for x and you'll get DFH =63-7, which is 56.
