28^2+45^2=53^2
Answer:
53 km
The slope - intercept form: y = m x + b
43 = 2 m + b ⇒ b = 43 - 2 m
36 = 4 m + b
------------------------
36 = 4 m + 43 - 2 m
36 - 43 = 4 m - 2 m
- 7 = 2 m
m = - 7 : 2
m = - 3.5
b = 43 - 2 · ( - 3.5 ) = 43 + 7 = 50
Answer:
Yulian`s situation is represented by the equation:
y = - 3.5 x + 50
Answer:
obtuse scalene since 6 square plus 5 square is 36+25= 61, and 8 squared is 64, so 61<64, and if the legs are less than the hypotenuse, it would be an obtuse triangle. all the side are also unequal so it's a scalene.
8/10*8/21
= 64/210
= 32/105
Answer:
There is a solution. Here's how:
Step-by-step explanation:
So, you work out the problem, and you lay it out here:
5-4+7+1=5-4+7x+1.
First, you start by subtracting 5 from both sides, which cancels both of the 5s. Here's your equation now:
-4+7+1=-4+7x+1
Next, you add 4 to both sides, which makes you identify the identity.
Here's your equation now:
7+1=7x+1
Now, you subtract 1 from both sides.
Here's your equation now:
7=7x
Finally, divide both sides by 7, while identifying the identity.
x=1.
