Solve 3x+4(x-8)-x=3/5(10x+15)
konstantin123 [22]

Answer:

Step-by-step explanation:

3x + 4(x - 8) - x = 3/5 (10x + 15)

3x + 4x - 32 - x = 3(2x + 3)

6x - 32 = 6x + 9

This is what I did. I'm not sure that this problem has a solution

Annual rent $ 7,380
jeyben [28]

Answer:

Part A:

Rent = $7380

Mortgage payments = $9800

Insurance = $145

Taxes, insurance, maintenance = 1780+1050 = $2830

Loss of Interest on security deposit = (650*6%) = $39

Interest lost on down payment and closing cost = (4,500*6%) = $270

Growth in equity = $225

Annual appreciation = $1700

Tax savings for mortgage interest = (9,575*28%) = $2,681

Tax savings for property taxes = (1,780*28%) = $498

Total rental cost = 7,380+145+39=7,564 dollars

Total buying costs = 9,800+2,830+270-225-1,700-2,681-498=7,796 dollars

Part B:

You should consider rent because the cost of renting is less than the cost of buying.

What’s the correct answer for this?
otez555 [7]

Answer:

0.7 + 0.4 - 0.2 = 0.9

Step-by-step explanation:

Let's denote the probabilities as following:

The probability that the show had animals is

P(A) = 0.7

The probability that the show aired more than 10 times is

P(B) = 0.4

The probability that the show had animals and aired more than 10 times is

P(A⋂B) = 0.2

The probability that a randomly selected show had animals or aired more than 10 times is P(A⋃B)

The correct form of  addition rule to determine the probability that a randomly selected show had animals or aired more than 10 times is:

P(A⋃B) = P(A) + P(B) - P(A⋂B) = 0.7 + 0.4 - 0.2 = 0.9

=> Option B is correct

Hope this helps!

A certain plant grows 134 inches every week. How long will it take the plant to grow 714 inches?
Bond [772]

The information we know:

1 week = 134 inches

x = 714

What I did was, I divided 714 by 134 to find the amount of weeks:

714/134 = 5.3

So, from the equation, basically, in 6 weeks (actually 5.3 weeks) the plant will grow 714 inches long
