Step 1: simplify
[3.4 ( 6 x + 2 ) +3] + 4 p -3 x
Pemdas!
6x+2=8x
3.4+3=6.4
6.4+8x=14.4
14.4x+4p=18.4xp+3= 21.4xpx
x=8
p=18.4
Other x = 21.4
You can write this in a proportion way: 6/55 = x/44.
Multiply both sides by 11 to get rid of the 55 and 44: 6/5 = x/4
Now, multiply both sides by 20: 5x = 24. x = 4.8
Therefore, he can run 4.8 miles in 44 minutes.
Answer:
B) 13
Step-by-step explanation:
Average age means to calculate mean:
Mean = (Sum of all numbers)/(Number of numbers)
Mean = (14 + 14.5 + 12 + 11.5 + 15 + 13 + 10.5 + 13.5)/8
Mean = (104)/8
Mean = 13
