A local car dealer is advertising a 2-year lease
MAVERICK [17]

Answer:

c = 150m+3000

Step-by-step explanation:

So if 150 is the monthly payment and c is the total cost you'd be looking for c and 150 would be multiplied by m for how ever many months is takes to pay it off. You would then just add on the 3000 dollar deposit since its just a one time payment to start out with.

Solve the formula for n. A=a+d(n-1) evaluate n when A=25, a=5, and d=13
ser-zykov [4K]

Answer:

Step-by-step explanation:

You;ll run into this formula a lot. Make sure you study it carefully.

A = 25

a = 5

d = 13

Find n

25 = 5 + 13*(n- 1)

20 = 13(n - 1)

This isn't going to work out. 20/13 does not give a whole number which it should.

Solve a, b, c, & d please & I will mark you as Brainliest.
laila [671]

Answer:

Step-by-step explanation:

a) -2x-3y=5\\-5x+3y=-40\\-7x=-35\\x=5, y=-5\\\\b)5x+6y=-14\\x-2y=10\\Considering\ equation\ 2,\\3(x-2y)=3(10)\\3x-6y=30\\Hence,\\5x+6y=-14\\3x-6y=30\\8x=16\\x=2, y=-4\\\\c) -3x+3y=21\\-x-5y=-17\\Considering\ equation\ 2,\\3(-x-5y)=3(-17)\\-3x-15y=-51\\Hence, subtracting\ both\ the\ equations\ we\ get,\\-3x+3y=21\\3x+15y=51\\18y=72\\y=4, x=-3

d) Let the cost of one group lesson be x and one private lesson be y

12x+2y=110\\10x+3y=125\\By\ multiplying\ the\ first\ equation\ with\ -1.5\ in\ this\ system\ we\ get,\\-1.5(12x+2y)=-1.5(110)\\-18x-3y=-165\\Hence,\ by\ adding\ both\ the\ equations\ we\ get,\\-18x-3y=-165\\10x+3y=125\\-8x=-40\\x=5,y=25
