The equation would be:
3.50 + 0.15x
x represents each 'late day'
1 yard = 3 feet = 36 in
so 1 in = 1/36 yard, 1 ft = 1/3 yard.
The volume of the layer of the topsoil, is:
5 in * 23 ft * 17 ft = 5 *(1/36)*23*(1/3)*17*(1/3) yard cubed =
(5*23*17)/(36*3*3)= 1955/324=6.034 yard cubed.
The store only sells increments of 1/4 = 0.25 cubic yards.
we need 6.034/0.25=24.136
So we need to buy 25 (24 will not be enough) increments of 1/4 cubic yards.
Answer: 25 increments of 1/4 cubic yard, that is 25*0.25=6.25 cubic yards.
Answer:
Two ratios equivalent to 27:9
A) 3:1
B)9:3

Answer: The width must be 25 feet or larger.</h3>
=================================================
Explanation:
x = width of the playground
x is some number which we don't know. Its basically a placeholder of sorts.
Multiply the width x by the length 40 to get x*40 = 40x
The area of the playground as an algebraic expression is 40x
We want this expression to be 1000 or larger, so we write this inequality (40x is greater than or equal to 1000)
Divide both sides by 40 and we end up with....
So x can be equal to 25, or it can be larger than 25.
In short, x must be at least 25 feet
$2.55. 0.15×3=0.45. So then you would take off 45 cents of the original 3 dollars to get $2.55
