Answer:
do we have to simplify it ??
Answer:
b=2
Step-by-step explanation:
Get rid of the parenthesis using distributive property:
6b+12+12b+6=54
Simplify
18b+18=54
subtract 18 from both sides
18b=36
divide by 18 on both sides
b=2
(x,y)
P = 50x + 80y
P=(0,5)
=50(0) + 80(5)
= 0 + 400
= 400
P=(1,12)
= 50(1) + 80(12)
= 50 + 960
= 1010
P=(4,10)
= 50(4) + 80(10)
= 2000 + 800
= 2800
Answer:
300 more times
Step-by-step explanation:
It is mentioned that a 12 years old blinks 150 times in 15 mins.
We know that 15 times 4 is 60 which results in 600 times in 60 minutes.
Again, an adult blinks 450 times in 30 minutes.
We know that 450 times 2 is 900
Next, subtract 600 from 900
equals to 300 times more
All you have to do is divided 43.54 divided by 3.5 which is 12.44 mph
