The width of the enlarged photo is 9 inches.
Given:
Original length = 2 inches
Original width = 1 inch
Extended length = 18 inches
Extended width = ?
2:1 = 18:x
2x = 1*18
2x = 18
2x/2 = 18/2
x = 9 * extended width.
to check:
2:1 = 18:9
2*9 = 1*18
18 = 18
Answer/Step-by-step explanation:
To solve the given expression, , the following steps as well as justification for each step is given below:
Step 1: state the given expression
(given)
Step 2: solve for x by subtracting 12.7 from each side of the equation.
Step 3: Apply the additive inverse rule and simplify (i.e the additive inverse of 12.7 is -12.7. when added, it gives us 0)
(additive inverse/simplification)
Step 4: additive identity rule (i.e. the 0 added to x = 0)
(identity property of addition)
The geometric mean would be 12
check the picture below.
recall that a flat-line is always 180°, and the sum of all interior angles in a triangle is 180°.
