1/2 or 0.5 x 3/4 or 0.75 = 0.375 or 3/8
the rest I dont' understand what you wrote, is it a subtraction or a negative?
<span>To find the length of the punt, we equate the expression to zero i.e. f(x) = 0 ,Given, f(x) is the height (in feet) and x is the horizontal distance (in feet) from the point at which the ball is punted. or (-16/1225)x^2 + (7/5)x + 2.5 = 0. On solving for x we get, x = 108 ft.</span>
Answer:
Make an eqaution from here.
Let’s make evening 2 “x”
So the first evening has 9 less then the secon evening so…
x-9
Of course theres the second evening (x).
X-9+x
Then the third evening has 4 times as much as the second meeting so…
x-9+x+4x
And when solved, it has to equal 105.
So solve from here.
Combine like terms.
6x-9=105
Isolate
6x=114
x= 19
First evening is 9 less then 19, so 10.
The second evening was 19 calls.
The third evening was 4 times the second evening so, 19*4= 76
1st night = 10
2nd night= 19 calls
Thrid night= 76 calls
