Answer:
Part a)
Part b)
Step-by-step explanation:
we know that
The scale is
That means
2.4 cm in the model represent 1 foot in the real
Part a) we know that
The restaurant is 20 feet tall
Find the height of the model
Multiply the actual height of the restaurant by the scale 2.4
A bottle cap is 1.2 cm tall
To find out the number of bottle caps divide the height of the model by 1.2
Part b) we know that
A popsicle stick is 15.2 cm tall
To find out the number of popsicle sticks divide the height of the model by 15.2
Convert to mixed number
A Prime Number can be divided evenly only by 1 or itself.
And it must be a whole number greater than 1.
Answer: (x+4) (x-3) (x+3)
Solving Steps:

Understand how I got it or should I explain where I got my numbers?
Answer:
y=17/3
Step-by-step explanation:
So you should make one -3y positive to cancel them out.
So multiply 2x-3y=43 by -1 and you get
-2x+3y=43
4x-3y=83
now +3y -3y cancel each other out
4x-2x=83-43
2x=50
x=25
Now enter 25 into the equation as x to find y
4(25)-3y=83
100-3y=83
100-83=3y
3y=17
y=17/3
