So, the arrow is telling us that we're going from the small rectangle to the big rectangle.
The 3 and the 7.5 are on the same side of the rectangle, right? So, let's try this backwards.
To get to 3 from 7.5, what do we divide by? (Hint: (7.5)/(3) Divide.)
The scale factor is the answer of the division, which is 2.5. We multiply 3 by 2.5 to get to 7.5.

Answer:
X=9/2-3/2
Step-by-step explanation:
1.Move the variable
2x=9-3y
2.Divide both side
X=9/2-3/2
the question in English
Draw a rectangle having the base congruent to the nine sevenths of the height.
Let
b-------> the base of rectangle
h-------> the height of rectangle
we know that
b=(9/7)*h-------> this is the equation to obtain the base of the rectangle for a given height
examples
1) for h=7 units
b=(9/7)*7-------->b=9 units
the dimensions are 9 units x 7 units------> see the attached figure
2) for h=5 units
b=(9/7)*5-------->b=(45/7) units
the dimensions are (45/7) units x 5 units
The answer in Italian
Facciamo
b-------> base del rettangolo
h-------> altezza del rettangolo
Noi sappiamo che
b=(9/7)*h-------> questa è l'equazione per ottenere la base del rettangolo per una determinata altezza
esempi
1) per h=7 units
b=(9/7)*7-------->b=9 units
le dimensioni sono 9 units x 7 units----->
vedere la figura allegata
2) per h=5 units
b=(9/7)*5-------->b=(45/7) units
le dimensioni sono (45/7) units x 5 units
Rita = $150
Bob = $150 - $35 = $115 Bob has $115
Joe = $115 divided by 5 = $23 $23 x 4 = $92 Joe Has $92
Tim = Has $50 more then joe, $92 + $50 = $142 Tim has $142
