First Way:
15(90-3)
=15(10*9-3)
=15*10*9-15*3
=150*9-45
=1,350-45
=1,305
-----------------
Second Way:
15(90-3)
=15(87)
=15(80+7)
=15(10*8+7)
=15*10*8+15*7
=150*8+(10+5)*7
=1,200+70+35
=1,200+105
=1,305
Answer:
Its B 5x-4y-3
Step-by-step explanation:
7x-3x+6+x-6y+2y-9
4x+6+x-6y+2y-9
5x+6-6y+2y-9
5x+6-4y-9
5x-4y-3
Answer:
As both these angles form a linear pair, they together will form 180°
So,
(2x + 45)° + x = 180°
=> 2x + 45 + x = 180°

Answer:
2 and 1
Step-by-step explanation:
5 could only go in 16 2 Times and 11 could only go in 17 1 time
We calculate this by multiplying the number of cookies by the number of boxes:
28*14=(20+8)*14=280+80+32=360+32=392 (that's how I like to count it, there are also other methods)
so she has 392 cookies in common.
