This is the concept of financial arithemetic;
We are required to calculate the total cost of leasing a new luxury car.
Here we shall use the formula;
total cost=[deposit+title fee+licence]+(monthly payment*number of months)
deposit=$658
title fee=$105
license=$80
monthly payments=6000
number of months=60
thus;
total cost=[6000+105+80]+[658*60]
total cost=6185+39,480
total cost=$45,665

Slove all of it please 100 points
Katyanochek1 [597]

Answer:

Step-by-step explanation:

5x+y-7=0 isolate y

y=-5x+7 (m=-5,b=7)

9x+7y-14=0

7y=14-9x ( divide both sides by 7)

y=-9x/7 +14/7

y=-9/7 + 2  (m=-9/7, b=2)

x+y=1000

4x+3y=3600 ( multiply the first equation by 3 to eliminate y)

3x+3y=3000

4x+3y=3600 ( subtract the two equations)

3x+3y-(4x+3y)=3000-3600

3x+3y-4x-3y=-600

-x=-600

x=600 ( substitute x in the equation)

x+y=1000

600+y=1000

y=1000-600=400

check : x+y=1000 , (600+400)=1000

check : 4x+3y=3600 = (4(600)+3(400))=2400+1200=3600

how many tickets are sold :

adults x=600/4=150

kids (y)=400/3=133 tickets+1 dollars left

unless( x represent kids then x=200, y represent adult = 100)

The width of a rectangular garden is 99 feet, and its length is 1212 feet. Three of these expressions equal the perimeter of the
zalisa [80]
You have not provided the choices, therefore, I cannot provide you with a specific solution. However, I will explain this problem for you to understand an apply on the choices you have.

Now, the perimeter of the rectangle is the summation of lengths of its four sides.
We have:
length = 12 ft
width = 9 ft

Therefore:
perimeter = 12 + 9 + 12 + 9 = 42 ft
Or: perimeter = 2(12+9) = 2*21 = 42 ft
Or: perimeter = 2*12 + 2*9 = 24 + 18 = 42 ft

Any expression that does not lead to the above result would be wrong

Hope this helps :)
