Answer:

Infinitely many solutions

Step-by-step explanation:

Step 1- Distribute into the parenthesis.

2x+12= 2(x+6)

2x+12= (2)x+(2)6

Step 2- Multiply

2x+12= 2x+12

Since they are equal, they are infinite.

Think of numbers that when they are divided by 10, the remainder is 9.
So numbers like: 19, 29, 39, 49, 59, 69, 79, 89, and 99.

Now numbers that when they are divided by 9, the remainder is 8.
So numbers like: 17, 26, 35, 44, 53, 62, 71, 80, 89, and 98.

Now the number that is alike from the two sets of numbers is n.
n=89

Double check your work.
Divide 89 by 10. Remainder of 9
Divide 89 by 9. Remainder of 8.

Hope this helps :)

Width of foil is $2\frac{1}{2}$ inches

Solution:

Given that area of the rectangle piece of foil is $11\frac{1}{4}$ square inches

Its length is $4\frac{1}{2}$ inches

To find: width of foil

The area of rectangle is given as:

To find the area of a rectangle, we multiply the length by the width

$\text{ area of rectangle}= length \times width$

Substituting the given values in above formula,

$11\frac{1}{4} = 4\frac{1}{2} \times width$

Let us solve above expression to find width

$\frac{4 \times 11 + 1}{4} = \frac{2 \times 4 + 1}{2} \times width\\\\\frac{45}{4} = \frac{9}{2} \times width\\\\width = \frac{45}{4} \times \frac{2}{9}\\\\width = \frac{5}{2} = 2\frac{1}{2}$

Therefore width of foil is $2\frac{1}{2}$ inches
