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
Answer: 10
Step-by-step explanation:
The interquartile range is the whole box but not the whiskers, so lowest number to highest number you take these two and subtract thus the answer is 10
20 - 30 = 10
60x24=1,440
103,680/1,440=72 beats per minute
an average human heart beats 72 to 80 beats per minute
x+2y=98
x=3y-22
3y-22+2y=98
5y=120
y=24
24 x 3 = 72-22=50
24*2 =48+50=98
the answer is c 50 and 24
