Answer:
16 apples, 20 pears
Step-by-step explanation:
36+4=40
So 40/2= 20 or an even amount of both apples and pears
20-4= 16 ~Original amount of apples
36-16=20 ~Amount of pears
Please take a photo of this problem... it looks very hard when it is written in the way you did.

Answer:
72
Step-by-step explanation:
The triangles are said to be similar. (ΔNPQ ~ ΔRSQ) That means corresponding sides have the same ratio:
NP/RS = NQ/RQ = PQ/SQ = 24/32 = 21/28 = 3/4
This ratio, or scale factor, also applies to the perimeters of the two triangles.
perimeter NPQ / perimeter RSQ = 3/4
Using the given expressions for the perimeters, we have ...
(7x +2)/(10x -4) = 3/4
We can solve this equation in the usual way to find the value of x. Then we can use that value to find the perimeter of ΔNPQ.
4(7x +2) = 3(10x -4) . . . . . multiply both sides by 4(10x -4)
28x +8 = 30x -12 . . . . . eliminate parentheses
20 = 2x . . . . . . . . . . . add 12-28x to both sides
10 = x . . . . . . . . . . . divide both sides by 10
The perimeter of ΔNPQ is ...
7x +2 = 7(10) +2 = 72
The perimeter of triangle NPQ is 72 units.
Product is the result of multiplying the numbers, so the <span>product of 8/15, 6/5,1/3 means that we have to multiply the three numbers, like this:
let's make them into one fraction:
