Answer:
6
Step-by-step explanation:
3+x+x=15
3+2x=15
2x=15-3
2x=12
x=12/2
x=6
7.) (x, y) —> (1/2*x, 1/2*y)
Step-by-step explanation:
It is given that, an air conditioning system can circulate 320 cubic feet of air per minute. We need to find how many cubic yards of air can it circulate per minute?
1 yard = 3 foot
1 feet = (1/3) yard
320 feet = 106.66 yard

So, it will circulate 11.85 cubic yard of air per minute.
2*2=4 first you multiply
4-1=3 then subtract
3+3=6 now you add and that is your answer =6
You are correct
12.2^2 x 3.14 x 6.1 = 2850.9
