Answer:
The width of the foil = w = 2.5 inches
Step-by-step explanation:
We know that the Area of a rectangular piece:
Here:
Given that area of the rectangular piece of foil:
Area = A = 11 1/4 square inches
= 45/4 square inches
= 11.25 square inches
Length = l = 4 1/2 inches
= 9/2 inches
= 4.5 inches
Using the Area formula
inches
Thus, the width of the foil = w = 2.5 inches
Answer:
Step-by-step explanation:
three times the sum of a number and 4...
3(n + 4) would be ur expression
First of what does a equal?
Answer:
Infinitely many.
Step-by-step explanation:
y = 3x + 4
2y = 6x + 8
Basically you would fill in the variable for y into the second equation.
2 (3x + 4) = 6x + 8
Multiply 2 by the part in the parenthesis.
2 * 3x = 6x
2 * 4 = 8
Set up the equation and solve
6x + 8 = 6x + 8
Because the sides are the same, they cancel each other out. When two sides equal the same variable they have infinitely many solutions.
Idk what you mean by which is better i guess you mean cheaper, if it is then
50x.20= 10,
35x10= 3.5 so 3.5 is less.
