Rt-2n=y -- add 2n
Rt=y+2n -- divide by R
t=(y+2n)/R
The scale factor of the model of the airplane is 1 feet : 15 feet.
<h3>What is the scale factor?</h3>
A scale drawing is a reduced form in terms of dimensions of an original image / building / object. The scale drawing is usually reduced at a constant dimension using the scale factor.
Scale factor = original dimensions / dimensions of the scale drawing
90 / 6 = 15
1 : 15

Ur answer will be C… basically u make the equation equal to zero and then use the quadratic formula to find ur answers…. x = -3 and 9
Equivalent expressions are expressions of equal values
The equivalent expressions are 4x+ (y - 8y) + (2z-5z) +6 and 6x-3x-6x + (2y - 10y) + (4 - 8) + (z - 88z)
<h3>How to determine the equivalent expressions</h3>
The first expression has been solved.
So, we have the following expressions
4x−7y−5z+6 and -3x−8y−4−87z
<u>4x−7y−5z+6</u>
We have:
4x-7y-5z+6
Rewrite as:
4x+ (y - 8y) + (2z-5z) +6
<u>-3x−8y−4−87z</u>
We have:
-3x−8y−4−87z
Rewrite as:
3x-6x + (2y - 10y) + (4 - 8) + (z - 88z)
Hence, the equivalent expressions are 4x+ (y - 8y) + (2z-5z) +6 and 6x-3x-6x + (2y - 10y) + (4 - 8) + (z - 88z)

Answer: (2p + 1.5d) + (5*(2)) = T
Step-by-step explanation: (2p + 1.5d) + (5*(2)) = T
Since there are no costs, i'll make up my own uwu;
Matinee = $5
Popcorn = $2
Drink = $1.5
T = total
(2p + 1.5d) + (5*(2)) = T
2p ($2 for each bag of popcorn - p represents popcorn)
1.5d ($1.5 for each drink, - d represents drinks)
5*2 ( 5 * 2 because we are already given the amount of matinee tickets they buy.
