1/7 I believe is the right answer
Given the equqation
W = 2H + 13
where
W is the weight in lb
H is the height in inches
If the height of a person is 5 ft 6 in, we must first convert it to inches. So,
H = 5(12) + 6
H = 66 in
The body weight then is,
W = 2(66) + 13
W = 145 lbs
It's distribution
8(y+9)
8y + 72
I found that Joe has 28 red pepper plants and 8 green pepper plants.
to find this, I first set up a proportion:
7/2 = (20+x)/x
then you cross multiply giving you:
7x = 40 + 2x
Subtract 2x from both sides:
5x = 40
solve for x:
x = 8 (which is the amount of green pepper plants)
to find how many red pepper plants he has, plug in x for (20 + x) giving you 28 red pepper plants
Hope I helped :)
