The cheetah is 7/6 the Perigen falcon is 10/3
Brilliant_brown [7]
The answer is 2  \frac{1}{6}.

Explanation:

In order to subtract the fractions, we must make them like fractions. To do this, the denominators must be the same by multiplying (only). Since the first fraction is \frac{10}{3}, 3 can be multiplied by 2 to get 6, which is the other fraction, we can multiply it. Whatever you do to the denominator you must do to the numerator. Now multiply 2 by the numerator (10) to get \frac{20}{6}. Now we can subtract the fractions \frac{20}{6} and \frac{7}{6} to get 13/6. Since this fraction is not in mixed fraction form yet, we must do that first.  goes into 13 twice, so the whole number is 2 and there is still 1 left, making the fraction \frac{1}{6}. Therefore, the difference is 2 \frac{1}{6}.

Find the equatio of the line tht contains the point (5,6) and is perpendicualr to the line 4x+2y=2
anzhelika [568]
--------------------------------------------------------------
Find Slope
--------------------------------------------------------------
4x + 2y = 2
2y= -4x + 2
y = -4/2 x + 2
y = -2x + 2

Slope = -2
Perpendicular slope = 1/2

--------------------------------------------------------------
Insert slope into the general equation y = mx + c
--------------------------------------------------------------
y = 1/2x + c

--------------------------------------------------------------
Find y-intercept 
--------------------------------------------------------------
y = 1/2x + c
at (5,6)
6 = 1/2 (5) + c
6 = 5/2 + c
c = 6 - 5/2 
c = 7/2

--------------------------------------------------------------
Insert y-intercept into y = 1/2 x + c
--------------------------------------------------------------
y = 1/2 x + 7/2
2y = x + 7

--------------------------------------------------------------
Answer: 2y = x + 7

A boat traveled 280 miles downstream and back. The trip downstream took 7 hours. The trip back took 14 hours. Find the speed of
Brrunno [24]
Let, the speed of boat = x 
Speed of current = y
So, x + y = 280/7
x + y = 40   ---- first equation

x - y = 280/14 
x - y = 20  
x = 20 + y

Substitute this value of x in first equation, 
20 + y + y = 40
2y = 40 - 20
y = 20/2
y = 10

Substitute this in first equation, 
x + 10 = 40
x = 30

In short, Speed of Boat = 30 mph, & speed of current = 10 mph

Hope this helps!
