Answer:
x=12
Step-by-step explanation:
14/21=16/(x+12)
cross multiply
14(x+12)=16(21)
14x+168=336
14x=336-168
14x=168
x=12 (so the side would be x+12=24)
You could also see that 14 is 2/3 of 21, so 16 has to be 2/3 of x+12. That means x+12 would have to equal 24. If you take the 12 away from 24, x=12.

Answer: 4.5
Step-by-step explanation:
S= ut + 1/2(at)
S= 10(1/2) + 1/2(-2x1/2)
S= 5 + 1/2(-1)
S= 5 + (-.5)
S= 4.5
Solution:
we are given that
Kathy stood on the middle rung of a ladder.
Since she climbed up 44 rungs, moved down 33 rungs...total up move of 44-33=11 rungs
Then climbed up 99 rungs. so a total of 11+99=110 rungs up.
Then she climbed up the remaining 33 rungs to the top of the ladder so total up move by 110+33=143 rungs
Since Kathy stood on the middle rung of a ladder so number of rungs=143x2=186
Now add the middle rungs.
Total number of rungs in the whole ladder=186+1=187
