Answer:
=x+22
-by-step explanation:
Let's simplify step-by-step.
3(x+4)+2(5−x)
Distribute:
=(3)(x)+(3)(4)+(2)(5)+(2)(−x)
=3x+12+10+−2x
Combine Like Terms:
=3x+12+10+−2x
=(3x+−2x)+(12+10)
=x+22

Answer:
Mean speed = 41.3 mph
Step-by-step explanation:
Given that,
The speeds of an automobiles are given below:
20, 35, 42, 52, 65, 49, 24, 37, 23, 41, 50, 58
We need to find the mean speed of the cars.
Mean = sum of observations/ no. of observation
So, the mean speed of the cars is equal to 41.3 mph.
Well first just multiply the things in the parenthesis by 3 and get -15c + 12d and then subtract 15 from 11 (because of the c) and get -4c +12d
24 students / 2 = 12 pairs
12-9 = 3 more pairs need magnets
3 * 3 = 9 more magnets
