Answer:

Step-by-step explanation:

x = number of cars

12x = 3.50x + 34

12x - 3.50x = 34

8.5x = 34

x = 34/8.5

x = 4 <=====he would have to sell 4 cars

aleksandr82 [10.1K]

Answer:

41 units

Pythagorean's  theorem,

Hypotenuse² = base² + adjacent²

Diagonal² = length² + width²

Century Go...

6 bills in the deposit were $10 bills.

<u>Step-by-step explanation:</u>

The total number of bills he gave the teller = 24 bills

x + y = 24 ------------(1)

Let,

x be the number of $5 bills.

y be the number of $10 bills.

The total bank deposit made using $5 and $10 bills are $150.

<u>He deposits $5 bills and $10 bills. So, the equation can be framed as : </u>

5x + 10y = 150 --------(2)

The question is asked for how many $10 bills were in the deposit,

Here 'y' is the number of $10 bills.

<u>To solve for y value : </u>

The eq(1) must be multiplied by 5 and subtract eq(2) from eq(1),

 5x + 5y = 120

-(<u>5x + 10y = 150</u>)

 <u>-5y = -30      </u>

⇒ y = 30/5

⇒ y = 6

Therefore, there were 6 bills in the deposit that are $10 bills.
