Answer: 22 houses.


Step-by-step explanation:

1. You can calculate the number of houses sold last month as following:

70houses*\frac{2}{5}=28houses

2. You can calculate the number of the remaining houses sold this month as following:

28houses*\frac{5}{7}=20houses

3. Then, the number of houses are left to be sold is:

70houses-28houses-20houses=22houses

3500 x 0.025 = 87.5

She paid 87.5$ dollars for the use of money

due date is after 6 months so

3500 times 6 = 21000

21000 times 0.025 = 525

She paid 525$ dollars on the due date

Jim is M years old. His daughter is 21 years yonger than him. How old is Jim's daughter. Express your answer in terms of M.
Gre4nikov [31]

Answer: M - 21


Step-by-step explanation:

Since his daughter is 21 years younger than he is (M) all you have to do is take his age and subtract 21 (how many years older he is) to get her age.


At first this might seem difficult because you don't know what M is equal to but in the context of this question you don't need to know M.

If you're ever stuck just give an imaginary number to M such as 50.

If you take 50 and subtract 21 you get 29, this makes sense because his daughter is of course younger than him.

You can also use this tatic to solve problems like x+3=x/2 (or something like that) just to check and make sure that the two equations do equal each other.

If y=4 when x=12, find y when x=-24
goldfiish [28.3K]

The value of y is -8 if the x  -24 and y varies directly with x, and If y = 4 when x = 12.

<h3>What is a proportional relationship?</h3>

It is defined as the relationship between two variables when the first variable increases, the second variable also increases according to the constant factor.

The question is incomplete.

The complete question is:

If y varies directly with x, and If y = 4 when x = 12, how do you find y when x = -24?

y ∝ x  (given)

y = kx

k is the constant of proportionality.

4 = 12k  (y = 4, and x = 12)

k = 1/3

y = x/3

Plug x = -24

y = -24/3

y = -8

Thus, the value of y is -8 if the x  -24 and y varies directly with x, and If y = 4 when x = 12.
