To solve this, write an equation to model the situation and solve the equation.

The equation can be: 3(x-9)=27

Then solve the equation.

3x-27=18

3x=45

x=15

Aleksandr-060686 [28]

Answer:

4.2 units

most likely answer choice B

Step-by-step explanation:

(1, 2) and (4, 5)

To find the distance between two points, we use the distance formula:

d = \sqrt{(x_{2}-x_1)^2 + (y_2-y_1)^2 }

Let's plug in what we know.

d = \sqrt{(4 - 1)^2 + (5 - 2)^2 }

Evaluate the parentheses.

d = \sqrt{(3)^2 + (3)^2 }

Evaluate the exponents.

d = \sqrt{(9) + (9) }

Add.

d=\sqrt{18}

Evaluate the radical.

d = 4.24

Round to the nearest tenth.

d = 4.2 units

*note: The answer choice is 4.6. I'm not sure if that is a typo on someone's end, but the distance between these two points is exactly 4.24264068712 units.

Hope this helps!

Divide 794.1 by 7.61 Point round off your answer to two decimal places
dolphi86 [110]
<span>By dividing the two numbers we get 104.3495... Rounding this number to two decimal places means that we must keep just 2 digits after the "." symbol, and round the last one of them. In our case, 104.3495... becomes 104.35.</span>
