Answer:
42 = the number of hats Paula can knit from one yard of yarn
Step-by-step explanation:
The way this problem is written, the constant 42 is the multiplier of yards to get hats. That is, it has units of hats per yard, so represents the number of hats that can be knit from 1 yard of yarn.

<em>Comment on the problem</em>
It seems more likely that the proportion should be written as ...
y = 42h
or
h = y/42
Then the constant would be the number of yards of yarn required for each hat.
Answer:
no
Step-by-step explanation:
the punctuation was a little confusing, but heres what i think u meant
"A grocery store is giving a reusable bag to every person who donates more then than 5.00 to charity, Courtney donates 1.25, will she get a bag?"
for this answer we see that x is the amount of money someone donates, so x has to be greater then 5.00, so the mathematical expression would be shown like this
x > 5.00
if x is not greater then 5.00 (like if its equal or less) then the store will not give a new bag, in this case 1.25 is not an amount that x can be
4x+28=-4+8x. 4x-8x=-4-28. -4x=-32. x=8
First calculate the radius = 1/2 the diameter = [sqrt sqr160(4-0)^2 + (-14-(-2))^2] / 2
= (sqrt 160 ) / 2 so r^2 = 160 /4 = 40
center = midpoint of the diameter = (-14-2)/ 2 , (4+0)/2 = (-8, 2)
so required equation is (x + 8)^2 + (y - 2)^2 = 40
