Answer:
x=?
Step-by-step explanation:
12xn=20xp
The answer to this question is squaring of areas
the numbers inside the () are first number is x second number is y so it is (x,y)
so for y<x the second number needs to be smaller than the first number
so right away (3,3) is not the answer
and then y also has to be greater then 2x-3
so replace x with the fist numbers and see what you get.
(2x2)-3 = 4-3 = -1 since -1 is not greater than -1 the second answer (2,-1) is not right
3rd one (-1,-2) 2(-1)-3 = -2-3=-5
so -2 is greater than -5 and -2 is less than -1 so the 3rd one is the answer
Answer:
1 fancy 15 plain
Step-by-step explanation:
F + P = 16
15F +10P = 165
Miltiplu the 1st by -10:
-10F -10P = -160
15F + 10P = 165
Add both (10p is cancelled)
5F = 5
F =1
16-1 = 15 (15plain)
15 x10 =150
1x15 =15
150 +15 = 165
