Answer: Hello there!
We know that the model is 28 inches long, and the scale of the model is 1/48 with respect to the real plane.
Now we want to know how long is the actual plane.
If the scale of the model is 1/48, this means that 48 models are equal in length to the actual plane. Then the length of the actual plane is 48 times the length of the model, this is:
L = 48*28 inches = 1344 inches, we could change the units for others more suiting for a plane, using that 1 feet = 12 inches, then we could write the length in feet using dividing the length in inches by 12.
L =1344/12 = 112 feets.
The algebraic expression for "4 inches more than twice Julie’s height" is 2x + 4, where "x" represents Julie's height in inches.
To translate the phrase "4 inches more than twice Julie’s height" into an algebraic expression, we use the variable "x" to represent Julie’s height.
Represent Julie's height with the variable "x".
Twice Julie's height is 2 times "x", which can be expressed as 2x.
Add "4 inches more" to the twice Julie's height, resulting in 2x + 4.
The final algebraic expression is 2x + 4, which represents "4 inches more than twice Julie’s height" in terms of the variable "x."
For example, if Julie's height is 5 inches (x = 5), the expression evaluates to 2(5) + 4 = 14, meaning she is 14 inches tall in this context.
