Hi,
To find the value of the number we have to first find the value of the single percantage of this number. We can do so by dividing 35 with 20.
The value of single percantage would be 1.75.
Mathematically: 1% = 1.75
Now to get the value of 50% we simply multiply the value of 1% with 50.
So 50% of unknown number is 87.5 that would be the ANSWER (D).
Hope this helps.
If you posses and other questions related to the answer leave a comment and I will reply.

Answer:
Average rate of change = 2
Step-by-step explanation:
We need to find the average rate of change of f(x) over the interval [-4,-1], so first we need to find the end points at x=-4 and x=-1.
From graph we see that y=-3 when x=-4, So the point is (-4,-3)
From graph we see that y=3 when x=-1, So the point is (-1,3)
Now we can plug these points into average rate of change formula:
where (a,f(a)) and (b,f(b)) are the given points.
Hence final answer is 2.
Answer:
A
Step-by-step explanation:
x^2 + x - 12
12 = 4*3,
We have -12 so 4 or 3 should be negative.
+ x , coefficient = +1 , so we have +4 - 3 = +1
(x+4)(x-3)
We can check:
(x+4)(x-3) = x^2 + 4x - 3x -12 = x^2 + x - 12
