The equation for the perimeter of a rectangle:
P = 2L + 2W
We’re given P and L and asked to find W:
15x + 17y = 2(7/2x + 7y) + 2W
15x + 17y = 7x + 14y + 2W
2W = 8x + 3y
W = 4x + 3/2y
Answer is A.
<span>Hey there, Lets solve this step by step.
</span>
<span>"Two times the quantity of a number minus 12”
</span><span>Two times the quantity = 2 * n
</span>
<span>number minus 12 = n - 12
</span>
Therefore
2n-12
4×10-1
40-1
39 is your answer
Prior to adding 75, the original data has a mean of 41/6 =6.833 & a median of 8
After adding the 75, the mean becomes 116/7 = 16.571 & the median = 9
So the median increased slightly (from 8 to 9) & the mean increased more quickly (from 6.833 to 16.571)
So it's C :The median increases less than the mean increases.
