Answer: 9 * (5 - y)
Explanation:
Times: multiplication
Difference: subtraction
y: the unknown variable
Answer:
2 /10
Step-by-step explanation:
The portion of the book that weight 2 1/8
Total number of books = 10
Number of books that weight 2 1/8 = 2
Fraction of book that weigh 2 1/8 = number of books that weigh 2 1/8 / total number of books
Fraction = 2 / 10
Without any more information we can't find the actual numerical representation of the length and width but we can give an expression that will allow us to find them...
We let the width equal x, so the length is 3x. That would be the dimensions...
length = 3x
width = x
So to find perimeter the expression would be
2(3x) + 2(x) =
6x + 2x =
8x
For the area it would be
a= length × width
a = 3x × x
a = 3x^2
Answer:
2x < 5
2x/2 < 5/2
x < 5/2
x ∈ ( -∞, 5/2 )
