48 + 32=80 s any thing that would equal 80 like 40+40 or 20x4
Answer:
First, let's address the general case.
When we have two points (a,b) and (c,d)
The distance between those points can be written as:
D = √( (a - c)^2 + (b - d)^2)
In this case, the points are:
(-2,4) and (2,4)
Then the distance is:
D = √( (-2 - 2)^2 + (4 - 4)^2) = √(-4)^2 = 4.
The equivalent expression to this is: |-2| + |2|
because:
I-2I = 2
I2I = 2
I-2I + I2I = 2 + 2 = 4.
D = 5
T16 = - 13 + 15(5)
= - 13 + 75
= 62
So the fraction would be 23/35 are boys. If you do the division (23 ÷ 35) the answer is around 0.657.
That converted into a percentage (×100) is 65.7%
Here is my answer. Hope it makes sense!
